The Silent Killer: An Introduction to Mesothelioma
Mesothelioma is a rare and deadly form of cancer that affects the lining of the lungs, heart, or abdomen. It is caused by the inhalation or ingestion of asbestos fibers, which become lodged in the lining of these organs and cause inflammation and scarring that eventually lead to cancer. Despite being a relatively rare disease, mesothelioma is incredibly deadly, with most patients surviving only a few months after diagnosis.
While treatments for mesothelioma have improved in recent years, early detection is key to improving survival rates. Unfortunately, many people who are exposed to asbestos don’t develop symptoms until decades later, making it difficult to catch the disease in its early stages.
In this article, we’ll discuss what causes mesothelioma and what you can do to protect yourself from this silent killer.
What is Asbestos and How Does it Cause Mesothelioma?
Asbestos is a naturally occurring mineral that was widely used in the construction industry from the 1940s through the 1970s. It is heat resistant, durable, and can be woven into fabrics, making it an ideal material for insulation, roofing, and other building materials.
Unfortunately, when asbestos fibers are inhaled or ingested, they can become lodged in the lining of the lungs, heart, or abdomen. Over time, these fibers can cause inflammation and scarring that eventually lead to cancer.
There are three types of mesothelioma, each named for the part of the body where the cancer develops:
| Type | Description |
|---|---|
| Pleural Mesothelioma | Occurs in the lining of the lungs and is the most common form of mesothelioma, accounting for approximately 75% of cases. |
| Peritoneal Mesothelioma | Occurs in the lining of the abdomen and accounts for approximately 20% of mesothelioma cases. |
| Pericardial Mesothelioma | Occurs in the lining of the heart and is the rarest form of mesothelioma, accounting for less than 5% of cases. |
Who is at Risk for Mesothelioma?
The primary risk factor for mesothelioma is exposure to asbestos. Those who work in the construction or manufacturing industries, particularly those who work with insulation, roofing, and other building materials, are at the highest risk of developing mesothelioma.
It is estimated that between 2,500 and 3,000 cases of mesothelioma are diagnosed in the United States each year. While the use of asbestos has declined in recent years, it is still present in many older buildings and poses a risk to those who work in these buildings or who live in homes built before the 1980s.
Other risk factors for mesothelioma include age (most cases are diagnosed in people over the age of 65), gender (men are more likely to develop the disease than women), and a family history of mesothelioma.
What are the Symptoms of Mesothelioma?
The symptoms of mesothelioma are often vague and non-specific, which can make it difficult to diagnose the disease in its early stages. Common symptoms of mesothelioma include:
- Chest pain
- Shortness of breath
- Coughing
- Fatigue
- Weight loss
- Abdominal pain and swelling (in cases of peritoneal mesothelioma)
- Irritation or pain in the eyes or skin (in cases of pericardial mesothelioma)
If you are experiencing any of these symptoms, particularly if you have a history of asbestos exposure, it is important to see a doctor right away.
How is Mesothelioma Diagnosed?
Diagnosing mesothelioma can be difficult, as the symptoms are often similar to those of other, more common diseases. Your doctor will likely start by taking a detailed medical history and performing a physical exam. They may also order one or more of the following tests:
- X-rays or CT scans to look for abnormalities in the lungs or abdomen
- A PET scan to determine if the cancer has spread to other parts of the body
- A biopsy, in which a small sample of tissue is taken from the affected area and examined under a microscope
What is the Prognosis for Mesothelioma?
The prognosis for mesothelioma is generally poor, particularly for those who are diagnosed in the later stages of the disease. However, early detection and treatment can improve outcomes. The five-year survival rate for mesothelioma is approximately 10%, but this varies depending on the type and stage of the cancer.
There are a variety of treatments available for mesothelioma, including surgery, radiation therapy, and chemotherapy. Your doctor will work with you to determine the best course of treatment based on the type and stage of the cancer, as well as your overall health and other factors.
How Can I Protect Myself from Mesothelioma?
The best way to protect yourself from mesothelioma is to avoid exposure to asbestos. If you work in an industry where you may be exposed to asbestos, be sure to follow all safety precautions and wear protective equipment as required. If you live in an older home or building, be aware of the signs of asbestos and have it removed by a licensed professional if necessary.
Frequently Asked Questions
Q: Is mesothelioma hereditary?
A: While there is no evidence that mesothelioma is hereditary, there is a slightly increased risk of developing the disease if you have a family history of it.
Q: How long does it take for mesothelioma to develop?
A: Mesothelioma can take anywhere from 20 to 50 years to develop after exposure to asbestos.
Q: Is there a cure for mesothelioma?
A: While there is no known cure for mesothelioma, there are treatments available that can help improve outcomes and extend survival.
Q: Can you get mesothelioma from secondhand exposure to asbestos?
A: Yes, it is possible to develop mesothelioma from secondhand exposure to asbestos. This can occur if you live with someone who works with asbestos or if you are exposed to asbestos fibers brought home on someone’s clothing or shoes.
Q: How is mesothelioma treated?
A: Treatment options for mesothelioma include surgery, radiation therapy, and chemotherapy. Your doctor will work with you to determine the best course of treatment based on the type and stage of the cancer, as well as your overall health and other factors.
Q: Does smoking increase the risk of mesothelioma?
A: While smoking is not a direct cause of mesothelioma, it can increase the risk of developing lung cancer, which can cause symptoms similar to mesothelioma.
Q: What is the difference between mesothelioma and lung cancer?
A: Mesothelioma is a cancer that affects the lining of the lungs or other organs, while lung cancer is a cancer that originates in the lungs themselves.
Q: Can mesothelioma be detected early?
A: Mesothelioma can be difficult to detect in its early stages, but regular check-ups and screenings can help identify the disease sooner.
Q: How long does mesothelioma take to develop?
A: Mesothelioma can take anywhere from 20 to 50 years to develop after exposure to asbestos.
Q: How common is mesothelioma?
A: It is estimated that between 2,500 and 3,000 cases of mesothelioma are diagnosed in the United States each year.
Q: Is mesothelioma only caused by asbestos?
A: While asbestos is the primary cause of mesothelioma, it is possible to develop the disease from exposure to other minerals, such as erionite and zeolite.
Q: Can mesothelioma be prevented?
A: The best way to prevent mesothelioma is to avoid exposure to asbestos. If you work in an industry where you may be exposed to asbestos, be sure to follow all safety precautions and wear protective equipment as required. If you live in an older home or building, be aware of the signs of asbestos and have it removed by a licensed professional if necessary.
Q: What are the chances of surviving mesothelioma?
A: The five-
year survival rate for mesothelioma is approximately 10%, but this varies depending on the type and stage of the cancer.
Q: What are the long-term effects of mesothelioma?
A: The long-term effects of mesothelioma can include chronic pain, fatigue, and difficulty breathing. However, the specific effects will depend on the type and stage of the cancer, as well as the course of treatment.
Q: Can mesothelioma be treated with alternative therapies?
A: While there is no evidence to support the use of alternative therapies for mesothelioma, some patients may choose to use alternative therapies in conjunction with traditional treatments.
