What is Mesothelioma?
Mesothelioma is a type of cancer that affects the mesothelial cells, which are found in the lining of the lungs, abdomen, and other organs. These cells produce a lubricating fluid that helps the organs move smoothly against each other. When these cells become cancerous, they begin to multiply uncontrollably, forming tumors that can spread throughout the body.
The most common cause of mesothelioma is exposure to asbestos, a naturally occurring mineral that was widely used in building materials, insulation, and other products until the 1980s. When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelial cells, causing inflammation and damage that can lead to mesothelioma.
Mesothelioma is a rare disease, with only about 3,000 cases diagnosed in the United States each year. It can take decades for symptoms to appear after exposure to asbestos, so many people who are diagnosed with mesothelioma are in their 60s, 70s, or older.
How Does Mesothelioma Develop?
Mesothelioma develops over a long period of time, usually 20 to 50 years after exposure to asbestos. When asbestos fibers are inhaled or ingested, they can become trapped in the mesothelial cells, causing chronic irritation and inflammation. Over time, this can lead to genetic mutations that cause the cells to become cancerous.
Once mesothelioma develops, it can spread quickly throughout the body. The tumors can invade nearby tissues and organs, making it difficult to remove them surgically. Because mesothelioma is often diagnosed late in its development, it can be difficult to treat effectively.
There are several factors that can affect the development of mesothelioma, including the length and intensity of asbestos exposure, the type of asbestos fibers that were inhaled or ingested, and individual genetic factors.
What Happens to the Cells in Mesothelioma?
Mesothelioma affects the mesothelial cells, which are found in the lining of the lungs, abdomen, and other organs. When these cells become cancerous, they begin to multiply uncontrollably, forming tumors that can spread throughout the body.
As mesothelioma develops, the cancerous cells can invade nearby tissues and organs, causing damage and inflammation. The tumors can also release fluid, which can build up in the affected area and cause additional symptoms.
There are four main types of mesothelioma, depending on where the tumors develop in the body:
| Type of Mesothelioma | Location in the Body |
|---|---|
| Pleural mesothelioma | Lungs and chest cavity |
| Peritoneal mesothelioma | Abdomen |
| Pericardial mesothelioma | Heart |
| Testicular mesothelioma | Testes |
The type of mesothelioma a person has can affect their symptoms, prognosis, and treatment options.
Let’s take a closer look at what happens to the cells in each type of mesothelioma.
Pleural Mesothelioma
Pleural mesothelioma is the most common type of mesothelioma, accounting for about 75% of all cases. It develops in the lining of the lungs and chest cavity, and can cause the following symptoms:
- Chest pain or discomfort
- Shortness of breath
- Chronic coughing
- Unexplained weight loss
- Fatigue
As pleural mesothelioma develops, the cancerous cells can invade the lung tissue, causing it to become stiff and less able to expand and contract properly. The tumors can also press against the chest wall, causing pain and discomfort. As fluid builds up in the chest cavity, it can put pressure on the lungs, making it even harder to breathe.
Peritoneal Mesothelioma
Peritoneal mesothelioma develops in the lining of the abdomen, and is the second most common type of mesothelioma, accounting for about 20% of all cases. It can cause the following symptoms:
- Abdominal pain or swelling
- Nausea or vomiting
- Unexplained weight loss
- Bowel changes
As peritoneal mesothelioma develops, the cancerous cells can invade the organs in the abdomen, causing them to become enlarged and inflamed. The tumors can press against the abdominal wall, causing pain and discomfort. As fluid builds up in the abdomen, it can cause swelling and distention.
Pericardial Mesothelioma
Pericardial mesothelioma develops in the lining of the heart, and is a rare and aggressive form of the disease. It can cause the following symptoms:
- Chest pain or discomfort
- Shortness of breath
- Persistent coughing
- Irregular heartbeat
As pericardial mesothelioma develops, the cancerous cells can invade the heart tissue, causing it to become inflamed and less able to function properly. The tumors can also press against the heart, causing chest pain and discomfort. As fluid builds up in the chest cavity, it can put pressure on the heart, making it even harder to function.
Testicular Mesothelioma
Testicular mesothelioma develops in the lining of the testes, and is the rarest form of mesothelioma, accounting for less than 1% of all cases. It can cause the following symptoms:
- Swelling or lumps in the testicles
- Pain or discomfort in the testicles
As testicular mesothelioma develops, the cancerous cells can invade the testicular tissue, causing it to become enlarged and inflamed. The tumors can also press against the scrotum, causing pain and discomfort.
