Mesothelioma Cancer: Early Recognition of Symptoms is Key to Successful Treatment

Symptoms of mesothelioma take many years to become apparent. In other words it has a long latency period. This makes it difficult to diagnose and treat. The person may repeatedly visit the doctor with the symptoms but more often considered as respiratory infections. The non-specific symptoms make it hard for even experienced doctors to make a quick and conclusive diagnosis with mesothelioma patients. Even people exposed to asbestos start showing the manifestation late in their life. By the time, mesothelioma is diagnosed, it is already widespread. However, the awareness of mesothelioma has made people detect it in early stages.

Manifestation of mesothelioma largely depends upon the location size and nature of the tumor. Sign and symptoms also depend upon whether the tumor is benign or malignant. Benign type of mesothelioma usually does not manifest itself. On the other hand, malignant type of mesothelioma has severe symptoms. It is mostly due to the pressure exerted on surrounding soft tissues. The malignancy may invade surrounding tissues or may result in pericardial or pleural effusion. Invasion of the chest wall may lead to chest pain.

The early symptoms to watch out for are:


    Hemoptysis or Blood in the sputum
    A cough or a change in cough pattern
    Dysphagia or Difficulty in swallowing
    Hoarseness
    Shortness of breath
    Pain in the chest or abdomen
    Significant Weight loss.

Among all types of mesothelioma, the pleural form is the most prevalent form. As a result the pleural symptoms are the most common manifestations of mesothelioma. When in early stages, the symptoms are more or less like pneumonia and hence often misdiagnosed. However these symptoms along with history of asbestos exposure should ring alarms for mesothelioma. Physicians should be well aware of it as usually they are the first to get in contact with the patient.

Pleural mesothelioma

Dyspnoea or shortness of breath along with chest pain is common manifestation of pleural mesothelioma. Pleural effusion caused by collection of fluid between the two linings of lungs and chest cavity may give rise to persistent cough. On chest radiography a build-up of fluid or pleural effusion may be evident indicating viral pneumonia.
The less common symptoms of pleural mesothelioma are:

    Chest pain
    Pain in the lower back
    Difficulty breathing
    Coughing
    Weight loss
    Fever
    Muscle weakness and sensory loss
    Swelling of the face and arms
    Hoarseness of voice
    Coughing up blood


A majority of patients do not show any sign and symptoms until late.

Peritoneal mesothelioma

It involves structures like abdomen, stomach cavity, liver, spleen or the bowel. The origin of peritoneal mesothelioma is usually abdomen, from where it spreads to adjoining organs. The symptoms of peritoneal mesothelioma are:

    Pain or swelling in the abdomen due to a build-up of fluid
    Nausea
    Weight loss
    Bowel obstruction
    Anemia or swelling of the feet
    Abdominal bloating due to fluid accumulation in the abdominal cavity
    Swelling of the feet
    Fever
    Impaired bowel function


The symptoms are a consequence of pressure exerted by the growing mass. This growing tumor can also cause breathing problems, and chest pain in addition to these symptoms. These symptoms result from tumors that lean against the abdominal wall. Mesothelioma in peritoneum, owing to its space occupying tendency may give rise to bowel obstruction, anemia, fever and problems with blood clotting.

Pericardial mesothelioma

Pericardial mesothelioma is a very uncommon form affecting the pericardium. Pericardium is the cavity between the linings of the heart. The tumor that grows in the tissue surrounding heart tends to spread from there. Pericardial mesothelioma sufferers may experience chest pain, shortness of breath, persistent coughing and palpitations. Involvement of the membrane around the heart (pericardium) may cause heart rhythm disturbances.

The symptoms for all types of mesothelioma become more acute and obvious with the progression of the disease. In spite of it, it can be mistaken as other disease condition. The only differentiating feature is the history of exposure of asbestos. Therefore, it is critical to investigate one's exposure to asbestos. Symptoms like pain in the lower back or at the side of the chest, shortness of breath, trouble swallowing, cough, fever, sweating, fatigue and weight loss may be very common, but the doctor should elucidate the history of asbestos exposure to rule out the presence of tumor.

What Are The Four Stages of Mesothelioma Cancer?

One rare form of cancer is called Mesothelioma, a malignant tumor in the mesothelial tissues of the lungs and the abdomen, arising from the inhalation of asbestos. Its rarity is one of the reasons why a lot of people are not aware of this kind of fatal disease. In fact, many people die of Mesothelioma undiagnosed. Although there is now a growing awareness of the hazards of asbestos to health, still many have not heard of Mesothelioma and thus, have not understood its nature, cause, signs and treatment. Even some physicians find it hard to detect Mesothelioma because its symptoms are akin to other diseases like lung cancer and pneumonia. Furthermore, it takes decades for a patient who was exposed to asbestos to develop Mesothelioma -- fifty years, at most.

Being unaware of Mesothelioma poses higher risks since it deters diagnosis and treatment. A person undergoing treatment must know the different stages of the cancer or the extent of the disease. Chances of recovering from Mesothelioma and the kind of treatment depend on the stage of the illness. There are basically two staging systems used for Pleural Mesothelioma (lungs): TNM system and Brighan system. These staging systems are also used in other kinds of cancers; however, the first is commonly used. There is no established method in determining the stage of the Peritoneal Mesothelioma cancer (abdominal) so the TNM system is used.

There are three variables in the TNM system: tumor, lymph nodes and metastasis. In the earliest stage of Mesothelioma, stage I, the malignant Mesothelioma cells start to grow and multiply only one layer of the pleura. The pleura is the membrane that encloses the lungs and lines the wall of the chest cavity. However, there are some instances wherein the pericardium (membrane that covers the heart) and diaphragm cover are already affected. In this case, the cancer patient is still in stage I Mesothelioma.

In the second stage, the two layers of the pleura are already affected by Mesothelioma. Take note, however, that in this stage, only one side of the body is affected. Normally, the pleura produces only small amount of lubricating fluid that allows easy expanding and contracting of the lungs. The excess fluid is absorbed by the blood and the lymph vessels so there's a balance between the amount of fluid produced and removed. During the second stage Mesothelioma, fluid starts to build up between the membrane of the lungs and the membrane of the chest wall, resulting to pleural effusion. The increase in the volume of fluid produced causes shortness of breath and chest pain. Other Mesothelioma cancer patients experience dry and persistent cough. Diagnosis of the pleural effusion is achieved through a chest x-ray.

Stage III Mesothelioma means that the malignant cells have already spread to the chest wall, esophagus and the lymph nodes on one part of the chest. The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn't respond well to medication, the cancer may advance to the fourth stage. The fourth stage Mesothelioma is formidable since at this stage the Mesothelioma cells have penetrated into the bloodstream and other organs in the body like the liver, the bones and the brain. The lymph nodes on the other side of the chest may also be affected by Mesothelioma in stage IV.

Brighan staging system, on the other hand, determines whether the Mesothelioma can be surgically removed or not and whether the lymph nodes are affected or not. In stage I Mesothelioma, the lymph nodes are not yet affected and the patient can still recover through surgery. In stage II, surgery can still be executed but some lymph nodes have already been infiltrated by the cancer cells. In stage III, the heart and chest wall are already affected; thus, surgery is no longer advisable. The lymph nodes in this stage, however, may or may not be affected. In the final stage, stage IV Mesothelioma, cancer cells have already gone to the bloodstream and other parts of the body like the heart, brain, bone and liver. In most cases, a patient who has reached stage IV Mesothelioma only has four to twenty-four months to live.
