Why is Mesothelioma So Deadly?

Mesothelioma, cancer of the mesothelium, is caused by exposure to asbestos. The disease can take decades to appear or to develop to the point that it is detectable. Once it forms, it takes time for the disease to be diagnosed and then treated. So why, exactly, is it so deadly?

One of the biggest problems with the disease is that it takes what seems like forever, to those who have been exposed to asbestos, to show up in tests. The disease usually takes around 20 years to develop but has been known to wait around 40 years to develop. What this means is that a person who knows he or she has been exposed to asbestos can wait a long time before a test shows anything either abnormal or serious.


This long period of inactivity means that individuals who do not know that they have been exposed to asbestos may ignore early signs and symptoms of the disease and explain them away as bronchitis or something else that will go away with time. This means that by the time they go see a doctor because they feel awful and can't breathe very well, the disease has progressed to the later stages.

Like all cancer, there is something very important in treatment about catching the disease early and getting treatment started as soon as possible. When a cancer is detected early and then treated early, the chances that it will be cured and the person's life saved go up drastically. The later cancer is detected in a person, the lower, usually, his or her chances of survival are.

Part of this is due to cancer's very aggressive nature. The unregulated growth of cancerous cells can quickly take over. Worse, in cancers located near major blood supplies or other fluid systems within the body, these cells can break away from the pack and end up halfway across the body and start a new colony.

Because most mesothelioma patients wait to see a doctor until they are having serious problems, they put themselves at risk and lower the chances that there is any hope for treatment. By the time most people go to see the doctor, the cancer has gotten to the point that it is inoperable. Chemotherapy and radiation can only do so much to kill cancer

Lung Cancer Warning Signs - Early Detection of Lung Cancer Can Save Your Life

Early detection of lung cancer warning signs - or any other types of illnesses - is crucial in helping to find a cure for the disease. Indeed, the earlier one is able to find out about the disease, the better chances they have for combating the illness.

Lung cancer warning signs are similar to recognizing the symptoms of the disease. Hence, having enough knowledge of other conditions associated with this illness would be helpful.

Below is a list of lung cancer warning signs you should be keeping a close eye on:


• Persistent Coughing
• Presence of blood or mucus when coughing
• Loss of appetite resulting to weight loss
• Feeling of shortness of breath
• Pneumonia, bronchitis, or other respiratory-related illness
• Constant pain in the chest, back, or neck
• Uncharacteristic fever

You need to pay close attention to any changes in your body though, since most of the symptoms are not evident until they have reached the advanced stage.
Once you have determined these symptoms, there are essential steps and further information you need to know.

Spread of Lung Cancer

Lung cancer is caused by the presence of cancer cells. These abnormal cells continue to divide on their own without following a particular order or pattern. Because of this nature in the cells, they have the potential to destroy the neighboring tissues of the body.

In fact, they can also develop into a malignant tumor which can invade your bloodstream and cripple the lymphatic system. The process known as metastasizing is responsible for the spread of cancer cells such that the initial cancer tumor can cause the growth of new tumors in various parts of the body.
In terms of determining the rate at which these cancer cells spread, it largely depends on the type of cells. But on average, tumor growth can happen in a span of a few months.

When To Consult A Doctor

As soon as you notice any of the symptoms listed above, it is best to meet with your doctor immediately. This will allow them to make diagnosis or assess your condition. Furthermore, the earlier you act on any lung cancer warning signs or symptoms, the more capable you are at preventing it from getting worse.

Immediate consultation with your doctor will enable them to further investigate the reason for such symptoms to exclude other health conditions.
Below is a list of what is recognized as late-stage lung cancer symptoms. One needs to work together with their physician to avoid reaching this stage:

• Inexplainable feeling of fatigue
• Reduced appetite
• Aches in your joints,bones, or constant headaches
• Bone fractures that are not brought about by injury
• Swelling on your face or neck
• Abnormalities in your neurologic conditions

Tests for Lung Cancer

Once you have seen with your doctor, the following tests are conducted to diagnose you:

1) Chest x-ray: This is mostly done for patients with complaints on excessive coughing and shortness of breath.
2) CAT Scan: This method of scanning in such areas as chest, head, abdomen, or pelvis helps assess the size of a tumor or evaluate how farther it has spread.
3) Bronchoscopy: In this method, your physician creates a direct visualization of your airways after numbing medications or sedations are administered.
4) PET Scan: This tool is used for assessing the tumor, which also utilize a chemical known as radionuclide. As soon as your first lung cancer warning signs become evident, it is best to undergo this test to help prevent the rapid growth of tumors.

Mesothelioma Cancer Stages Explained (part 2)

Sorry for the late posting...here next articles about mesothelioma cancer stages explained...

The Causes

Mesothelioma cancer is caused by exposure to asbestos fibers or dust. Workers in the asbestos industry are prime targets for attracting this deadly disease. Asbestos fibers enter the body, either by breathing in the tiny asbestos fibers or by swallowing them. The fibers cause healthy cells to mutate into cancer. Since the body is unable to dispel these fibers, the lungs become inflamed (asbestosis). This condition worsens and eventually becomes malignant. Asbestos exposure is thought to be responsible for roughly 75% of all cases of lung lining cancer.

Symptoms

Mesothelioma is a very difficult cancer to detect in early stages. The early symptoms tend to be generic and even nonexistent in some cases, and it can take as much as 15 to 50 years after exposure to develop. The first symptom is often constant chest pain, followed by coughing, lung damage, and shortness of breath. Patients who have peritoneal mesothelioma (a less common form of mesothelioma) generally experience abdominal pain, loss of appetite, nausea, and abdominal swelling, often in addition to the symptoms of pleural mesothelioma. They may also develop bowel obstruction or further breathing obstruction.


Stages and Diagnosis of Mesothelioma

There are three staging systems used to determine treatment for mesothelioma: Butchart System, TNM System, and the Brigham System

Butchart Staging System

The Butchart System is the oldest system and the most common. This system concentrates upon determining the extent of primary tumor mass and divides mesothelioma into four stages.

Stage I of the Butchart System consists of the presence of mesothelioma in the lining of the right or left lung and may also involve the diaphragm on the same side. Stage II includes the progression of mesothelioma into the chest wall, esophagus, or lung lining on bother sides. There may also be lymph nodes in the chest. The onset of Stage III begins when the mesothelioma surpasses the diaphragm into the lining of the abdominal cavity or peritoneum. In this stage the cancer may also affect the lymph nodes extending beyond those in the chest. Doctors identify Stage IV, the final stage, when evidence of the spread of cancer to other organs (metastasis) is confirmed.

TNM System

Stage I of the TNM System involves the lining of the right or left lung, pericardium, or diaphragm on the same side. At this stage, lymph nodes are not involved. Stage II begins when mesothelioma spreads from the lining of the lung on one side to a lymph node on the same side. At this stage, the cancer may also spread to the lung, pericardium, or diaphragm on the same side. Stage III begins when mesothelioma is present in the chest wall, muscle, ribs, heart, esophagus, or other organs in the chest on the same side as the primary tumor. In the final stage, Stage IV, the mesothelioma has travelled into the lymph nodes in the chest on the side opposite the primary tumor, into the lung opposite the primary tumor, or directly into the organs in the abdominal cavity or neck. Metastasis is the final result in this stage.

Brigham System

The Brigham System determines the resectability (the ability to surgically remove) the mesothelioma mass. In Stage I the tumor is resectable, while lymph nodes remain unaffected. In Stage II the tumor remains respectable but the mesothelioma affects the lymph nodes. In Stage III the tumor becomes unresectable. It has penetrated through the diaphragm, or peritoneum. Stage III can occur with or without lymph involvement and extends into the chest wall and heart. Stage IV occurs when doctors discover metastatic disease involving distant organs.

After doctors identify the stage of a patient's malignant mesothelioma, the patient and doctor consider the various treatment options available. Mesothelioma treatment programs are contingent upon many factors, including the stage of the cancer, the location of the cancer, the spread of mesothelioma cancer, the characteristics of the cancer cells under a microscope and the patient's age and concerns.

Mesothelioma Alternative Therapy - What Are Your Options?

Quite a number of patients afflicted with asbestos related diseases such as asbestosis and mesothelioma now-a days use different types of complimentary and alternative therapies in addition to conventional therapies like surgery and drugs.
These alternative therapies are used by patients coping with asbestos related disease as a form of pain management, to improve general health, and also to provide symptomatic relief.

Although these treatments do not offer a cure, they certainly help you to live more comfortable lives by providing relief from pain and stress.
The most commonly used alternative therapies include the following:


1}Acupuncture
This is one of the commonest forms of available alternative therapies today, and there are a lot of insurance companies offering coverage for this type of treatment. Acupuncture involves the insertion of extremely fine needles into pressure points at clearly defined locations in the skin to improve the balance and flow of factors called the Yin, Yang, Qi and Blood in traditional Chinese medicine.
This form of treatment provides relief from chronic pain, inflammation, anxiety and stress and it is one of the most commonly used alternative medicines in the treatment of asbestos related diseases.

2}Aromatherapy
This form of alternative therapy involves the use of fragrances to improve physical and psychological well being. The fragrances are applied in liquids called essential oils, which are distilled and highly concentrated plant based oils. Aromatherapists use these fragrances combined in the oils to provide pain relief and to improve the general well being of the patient.
Aromatherapy is often combined with massage , you receive a massage with carrier oils that have been mixed with small amounts of essential oil fragrances.

3}Massage
Massage therapy has been shown to provide a number of important health benefits. It improves blood and lymphatic flow and it is used to improve blood circulation. It also improves muscle tension.
Massage also stimulates nervous and digestive systems, relieve chronic pain and improve skin function. Many patients find this type of therapy useful in reducing anxiety and stress as well as reducing chronic pain.

4}Meditation
Meditation is a well known way of relieving stress, anxiety and depression. Meditation is now also used to manage pain and other symptoms of diseases. Many cancer patients add meditation to their treatment schedules to help to reduce pain, stress and anxiety. Certain studies have shown that meditation may be able to reduce tumor growth and improve your prognosis.

5} Supplements
Dietary supplements include vitamins, minerals, herbs, and amino acids. Vitamins, minerals, and amino acids are all needed by the body to carry out essential life functions, and supplements can help provide necessary chemicals when diet alone cannot. Many herbs can help treat diseases and conditions, as well as provide symptomatic relief. For example, flaxseed, ginseng, and garlic are all known to reduce blood pressure.
When it comes to supplements, it's very important to let your physician know the kind of supplements you are taking, as they can affect how well your prescription medications work. Some supplements can even have dangerous interactive effects when taken in conjunction with certain prescription medications.

6} TENS Therapy
Transcutaneous Electrical Nerve Stimulation - commonly known as TENS therapy - is somewhat similar to acupuncture, in that this treatment stimulates certain defined body locations. However, while acupuncture uses fine needles, TENS therapy stimulates body points with the use of electrodes that deliver very mild electrical shocks.
Unlike many other types of complementary and alternative therapy, TENS has actually been approved by the FDA. While this doesn't automatically mean that TENS can provide a cure when it is used, it does mean that the treatment has been determined to be safe according to FDA regulations, and also means that TENS therapy is covered by insurance.

7} Yoga
The origins of yoga lie in India, where this ancient art is practiced more for spiritual reasons than for health-related reasons. Outside of India, yoga has become a popular form of exercise that is physically and psychologically calming and strengthening. Learning simple yoga techniques can help improve general health by toning and strengthening muscles, improving flexibility, and improving general health and one's state of mind.

8} Pet Therapy
Also known as animal-assisted therapy or animal-assisted activities, this type of therapy aims to improve the general health and well-being of patients by allowing them to interact with a variety of animals. The wonderful effects of animal interaction has long been known - the simple act of stroking a cat or dog can improve the mood, lift the spirits, and even provide some physical benefits (such as the temporary lowering of blood pressure). Pet therapy techniques can be used for a wide variety of medical conditions. For example, a physical therapist working with a person recovering from a stroke might bring a dog to a therapy session and have the patient brush the dog to help improve their motor skills.

Causes of Mesothelioma - An Insight Into the Likely Causes of Mesothelioma

Mesothelioma is a very aggressive and rare cancer that is difficult to diagnose and that is also highly resistant to treatment. Around 2000-3000 new cases of malignant mesothelioma are seen every year in the US, and these figures are expected to rise over the next decade.

What causes mesothelioma?

There is extensive and undeniable medical evidence that mesothelioma is caused by exposure to asbestos fibers. There is no other known cause.

Asbestos is a naturally occurring fibrous material that was widely used in industrial, commercial and domestic products throughout the 20th century. It was particularly popular because of its durability, fire resistant and insulating properties. It was used in several thousand different manufactured asbestos products.
These included construction materials, household appliances and brake linings, the use was so widespread that millions of Americans were unknowingly exposed to the toxic material, which now leads to the development of mesothelioma amongst million of Americans.


Most of the companies that manufactured these asbestos contaminated products were aware of the danger of asbestos, but still preferred to put millions at risk to make huge profits.

However today, as more cases are being diagnosed and they are seeking for legal compensation, these companies are being ordered to pay compensations to patients affected by asbestos.

How does asbestos cause mesothelioma?

Internal organs and body cavities are lined by a thin tissue called mesothelium. This lining lines the lungs {pleura} and it also lines the heart sac {pericardium} and abdominal cavity {peritoneum}.
This mesothelial tissue offers protection and support for the internal organs and body cavities. It also provides lubrication to help organ function properly and be in good health.

Mesothelioma affects this lining of various organs and body cavities, mostly the pleura, pericardium, and peritoneum. Occasionally and rarely, the cancer may affect the lining of the testicles, called the tunica vaginalis.

Although the actual mechanism by which asbestos causes cancer is not known, there are about four different theories to explain this:

1-Asbestos causes irritation and inflammation of mesothelial cells, which results in irreversible scarring, cellular damage, and eventually cancer

2- Asbestos fibers enter cells and disrupt the function of cellular structures that are essential for normal cell division, causing cellular changes that lead to cancer.

3-Asbestos causes the production of free radicals. These molecules damage DNA, and cause cells to mutate and become cancerous.

4-The presence of asbestos causes cells to produce oncoproteins. These molecules cause mesothelial cells to ignore normal cellular division restraints, and this can lead to the development of cancer.

The common underlying pathophysiology in each of these theories is that asbestos cause's cellular damage mainly by causing the cells of the mesothelium to divide and multiply without restraint causing the formation of tumors. This uncontrolled division causes impairment of the normal function of the body organs and tissues.

Does Mesothelioma have other causes?
Although research and medical evidence has not been able to directly prove any other cause of mesothelioma other than asbestos exposure, it is known however that smoking can aggravate a less serious asbestos related disease, such as asbestosis, and prompt formation of tumors and the onset of the cancer.

Also asbestos exposure and smoking have a synergistic effect that increases the risk of developing lung cancer by as much as 84 times or more. Thus people that have been exposed to asbestos for a prolonged period of time are advised to not to smoke.

Mesothelioma Cancer Stages Explained (part 1)

Mesothelioma cancer is a type of cancer that attacks the lungs and chest cavity. Also known as asbestos lung cancer, it forms deadly tumors where mesothelial cancer cells form a protective lining over the lungs, heart, and abdominal organs. It is a type of lung cancer that takes many years to develop and produce symptoms. Roughly 3,000 cases per year (mostly men over the age of 40) are reported. It is estimated that number will grow to about 300,000 cases before 2030.

Types of Mesothelioma Asbestos Cancer
Epithelial mesothelioma is a rare and fatal form of cancer affecting the membrane lining of the chest cavity, heart, lungs, and abdominal cavity. There are three forms of epithelial mesothelioma: the most common is Pleural Mesothelioma, the second most common, Peritoneal Mesothelioma (accounting for only a quarter of the cases), and the rarest form, pericardial mesothelioma.


Pleural mesothelioma, the most common type of this disease involves the pleura, a thin membrane located between the lungs and the chest cavity. The pleura provide a lubricated surface so that the lungs do not rub and chafe against the chest walls. There are two types of pleural mesothelioma the first being 'diffuse and malignant'. This type is cancerous and is generally fatal within a year of diagnosis. The second type is 'localized and benign' and is generally non-life threatening. It can usually be removed through surgery.

Lung Lining cancer is not to be confused with lung cancer. In lung lining cancer, the effected area of the body is called the mesothelium, a thin membrane that covers many of the internal organs of the body. The mesothelium of the lungs is called the pleura. Lung Lining cancer is also sometimes called mesothelioma after the area in which it occurs.

This thin membrane is comprised of two layers - one that surrounds the organ and another that forms an exterior sac around the first layer. Between the layers of the mesothelium is a fluid that allows vital organs to glide easily against objects that come in contact with them.

Localized pleural mesothelioma is not always caused by asbestos exposure. However, if it has spread to other parts of the body, for instance the lymph nodes, lungs, chest wall, or abdominal organs, then it is considered malignant and is more often than not the result of asbestos exposure.

Peritoneal mesothelioma appears as a tumor in the peritoneum membrane of the abdomen. This type of mesothelioma is very rare, comprising less than a fourth of all known cases of the disease. There are no effective treatments for this condition, and most patients live less than a year after diagnosis.

Mesentery cancer is likened to peritoneal cancer (mesothelioma). This cancer primarily affects the sections of the peritoneum that attach different organs to the wall of the abdominal cavity, (i.e. mesogastrium for the stomach, mesojejunum for the jejunum). Mesentery cancer includes all abdominal peritoneal extensions. Tumors rarely originate in the actual mesentery, though it is a frequent route for the spread of mesothelioma through the abdominal cavity.

Pericardial mesothelioma is the rarest form of mesothelioma, affecting the membrane around the heart (called the pericardium or pericardial sac). In this disease, solid masses and effusion (fluid) develop around the pericardium. Not all effusions are strictly related to mesothelioma.

Exposure to airborne asbestos particles increases one's risk of developing malignant mesothelioma

Mesothelioma diagnosis of malignant mesothelioma has a peak incidence 35-45 years after asbestos exposure. Malignant mesothelioma is a rare type of cancer in which malignant cells are found in the sac lining the chest or abdomen. Most people with malignant mesothelioma have on worked on jobs where they breathed asbestos.
It can also occur in children; however, these cases are not thought to be associated with asbestos exposure.

Most people who develop mesothelioma get worked on jobs where they inhaled asbestos particles, or have been exposed to asbestos dust and fiber in other ways, such as by washing the clothes of a family member who worked with asbestos, or by home renovation using asbestos cement products.


Treatment options a mesothelioma diagnosis for the management of malignant mesothelioma includes surgery, chemotherapy, radiation, and multimodality treatment. Surgery in victims with disease confined to the pleural space is reasonable.
Extrapleural pneumonectomy is a more extensive procedure and has a higher mortality rate. Recently, the mortality rate has been lowered to 3.8%. It involves dissection of the parietal pleura; division of the pulmonary vessels; and en bloc resection of the lung, pleura, pericardium, and diaphragm followed by reconstruction. It provides the greatest local control because it removes the entire pleural sac along with the lung parenchyma.

The 2 surgical procedures used are pleurectomy with decortication and extrapleural pneumonectomy.

Surgical resection has been relied upon because radiation and chemotherapy get hold of been ineffective unequivocal treatments. There are now a number of cancer treatment options open to mesothelioma patients. Extrapleural pneumonectomy for selected victims with very early stage disease may expand recurrence-free survival, but the impact it has on overall survival is unknown at this time.

Mesothelioma diagnosis can be intimidating and can scare a lot of people, but mesothelioma diagnosis may give you a fighting chance if can be diagnose early. So do yourself a favor if you think that what you are suffering from and had worked in an asbestos related workplace.

The purpose of such investigations in mesothelioma diagnosis is to confirm and to determine the type of mesothelioma, to 'stage' the disease (measure how severe it is), and so to assess whether the disease is operable.

Information You Need to Know on the Rare Form of Cancer Mesothelioma

Mesothelioma is a rare form of cancer where the malignant cells are found in the mesothelium. The mesothelium is a protective sac that covers most of the body's internal organs. The most common way people develop this is through inhaling asbestos particles at a job where this is possible. Mesothelioma asbestos is something you certainly need to be wary of if you suspect this being a possibility at your job.

The disease occurs when the cells of the mesothelium become abnormal and divide without control or order. The cells can then invade and damage nearby tissues and organs. These cancer cells can also spread from the original place to other parts of the body which is a huge concern with this form of cancer. It typically begins as pleura mesothelioma as this is where it originates from.


Mesothelioma rates have certainly increased over the past 20 years, but fortunately it is still a fairly rare form of cancer. On average there are about 2,000 new cases diagnosed in the United States each year. You will find that this is more common in men than with women and the risk certainly increases with age.
While there are various mesothelioma symptoms to be aware of, they may not occur until 30 to 50 years after exposure to asbestos. This can make it increasingly difficult to stop before it is too late. However, some of the symptoms to watch for include shortness of breath and pain in the chest because of the accumulation of fluid in the pleura.

Other symptoms to be aware of for peritoneal mesothelioma include weight loss and abdominal pain and swelling. The reason for this is because of a buildup of fluid in the abdomen. You may also want to watch out for bowel obstruction, blood clotting, and fever.

After learning about this mesothelioma information, you are probably curious as to treatment methods. There are a few ways different mesothelioma treatment methods you can pursue. It really depends on the location of the cancer, the stage of the disease, and the patient's age and overall health.

Mesothelioma - Most Commonly Asked Questions

Mesothelioma is an uncommon cancer that affects primarily the mesothelium which is a protective sac covering most of the body's internal organs. Exposure to asbestos particles at the place of work has been strongly linked to the development of mesothelioma in most of the victims.

Some of the most frequently asked questions on mesothelioma are:

1- Is there any ongoing research to discover new treatments for mesothelioma?
Yes, there are new treatments that are being studied. The National Cancer Institute {NCI} is sponsoring clinical trials {research with people} which are designed to find new modes of treatment and also to discover better ways of using currently used treatments.
Most of these treatments are still undergoing clinical trials by doctors to find out whether the treatments are safe for patients and whether they are effective against the disease before they can be recommended for general use.
Mesothelioma victims can offer themselves for participation in these clinical trials as a treatment option. Information about clinical trials is available from the Cancer Information Service{CIS} at 1-800-4-Cancer.

2- How can Mesothelioma be treated?
The treatment of mesothelioma depends on, the location of the cancer,stage of the disease, and patients age and general health.
Treatment options include
a} Chemotherapy,
b} Radiotherapy,
c} Surgery.

These forms of treatment are sometimes combined.
- Chemotherapy: This involves the use of anticancer drugs to selectively destroy and kill the cancer cells in the body. Most of the anticancer drugs are administered intravenously. Ongoing research into possibility of direct administration of anticancer drugs into the chest or abdomen is currently being studied.
- Radiotherapy: This involves the use of high energy rays {radiation} to kill the cancer cells and debulk {shrink} tumors. The radiation is directed only at the affected area of the body to kill the cancer cells.
Radiation can be from an external machine placed outside the body {external radiation},or it could be form an internal source where the material releasing the radiation is placed inside the area of the body affected by cancer cells. It is placed with the use of thin plastic tubes.
- Surgery: This is a very common mode of treatment in treating mesothelioma. The surgeon may remove part of the lining of the chest and abdomen and some of the surrounding tissue. Sometimes an operation called pneumonectomy is done during which a whole lung is removed. Other forms of surgery involves the removal of part of the diaphragm, this is the muscular sheet separating the chest cavity from the abdominal cavity.

Mesothelioma Diagnosis - What You Need To Know

If the chest x-ray is suggestive of malignant mesothelioma, it is likely that further investigations will be ordered, especially if compensation may be sought. These investigations may include additional imaging studies, blood tests, bone scans, and lung-function tests, as well as more invasive procedures such as thoracentesis, thoracoscopy, pleuroscopy or a lung biopsy. This is a typical mesothelioma diagnosis.

Mesothelioma diagnosis can be done through chest x-ray. The typical abnormalities seen on chest x-ray in patients with malignant mesohtelioma are pleural effusion (a collection of fluid in the space between the 2 layers of the pleura), or it is called pleural thickening.

Unlike lung cancer, there is no association between mesothelioma and smoking Malignancies involving mesothelial cells in these spread cavities are known as malignant mesothelioma, which may be localized or diffuse. Mesothelioma is the word used to describe a cancerous tumor that involves the mesothelial cells of an organ, often the lungs, heart, or abdominal organs.

Mesothelioma diagnosis in this disease, malignant cells develop in the mesothelium, a protective lining that covers transcendently of the spread's internal organs. Greatest malignant mesothelioma set up complex karyotypes, with extensive aneuploidy and rearrangement of tons chromosomes.

Symptoms of mesothelioma may not appear until 20 to 50 years after exposure to asbestos. Mesothelioma diagnosis is often difficult, because the symptoms are similar to those of a number of other conditions. A history of exposure to asbestos may increase clinical suspicion for mesothelioma.
A physical examination is performed, followed by chest X-ray and often lung function tests. The X-ray may reveal pleural thickening commonly seen after asbestos exposure if mesothelioma diagnosis is done.

If the cancer has length beyond the mesothelium to other parts of the size, symptoms may include pain, trouble swallowing, or swelling of the neck or engage.
Symptoms of peritoneal mesothelioma include weight loss and cachexia, abdominal swelling and suffering due to ascites (a buildup of fluid in the abdominal cavity).
