What is the Difference Between Mesothelioma and Small Cell Lung Cancer?

As we all know, cancer is a term used for the uncontrolled growth of abnormal cells in the body. Although cancer can occur at any part of the body, lung cancer is one of the most common types of cancer worldwide. Among lung cancers, there are two specific types, namely mesothelioma and small-cell lung cancer. Although both types of cancers are associated with lungs, there are some significant differences between them. In this article, we will discuss what mesothelioma and small cell lung cancer are, and what the difference is between them.

What is Mesothelioma?

Mesothelioma is a rare form of cancer that develops in the thin layer of tissue that covers the majority of the internal organs of the body. Although it can occur in various parts of the body, it commonly affects the lining of the lungs, abdomen, and heart. It is caused by exposure to asbestos, a group of naturally occurring minerals found in rocks and soil. When asbestos is disturbed or damaged, tiny fibers are released into the air, and when inhaled, they can become trapped in the lungs, leading to the development of mesothelioma over time.

Symptoms of Mesothelioma

As mesothelioma is a rare form of cancer, it is often diagnosed in its advanced stages when treatment options are limited. Some common symptoms of mesothelioma include:

Common Symptoms of Mesothelioma
Fatigue
Chest pain
Shortness of breath
Persistent coughing
Unexplained weight loss

As these symptoms are not specific to mesothelioma, it is often misdiagnosed as other lung conditions. Therefore, a proper diagnosis is essential to determine the type of cancer and its stage.

What is Small Cell Lung Cancer?

Small cell lung cancer is a type of lung cancer that is commonly associated with smoking. It is referred to as small cell carcinoma as the cells of this type of cancer are small in size and have the ability to spread quickly to other parts of the body. It accounts for approximately 10 to 15 percent of all lung cancer cases and is usually detected in the advanced stages.

Symptoms of Small Cell Lung Cancer

Some common symptoms of small cell lung cancer include:

Common Symptoms of Small Cell Lung Cancer
Chest pain
Coughing up blood
Shortness of breath
Unexplained weight loss
Hoarseness
Loss of appetite

As these symptoms are also not specific to small cell lung cancer, it is often misdiagnosed as other lung conditions. Therefore, a proper diagnosis is essential to determine the type of cancer and its stage.

The Difference Between Mesothelioma and Small Cell Lung Cancer

Although both mesothelioma and small cell lung cancer are associated with the lungs, there are some significant differences between the two types of cancer.

Causes

As mentioned earlier, mesothelioma is caused by exposure to asbestos, whereas small cell lung cancer is commonly associated with smoking. Exposure to radon gas, air pollution, and other harmful chemicals can also increase the risk of developing small cell lung cancer.

Symptoms

Both mesothelioma and small cell lung cancer share some common symptoms, such as chest pain, shortness of breath, and unexplained weight loss. However, small cell lung cancer is more likely to cause coughing up blood and hoarseness, whereas mesothelioma is more likely to cause abdominal pain and swelling.

Treatment

Depending on the stage of cancer and overall health, treatment options for mesothelioma and small cell lung cancer can vary. Mesothelioma is usually treated with surgery, chemotherapy, and radiation therapy, while small cell lung cancer is often treated with chemotherapy and radiation therapy. Immunotherapy, targeted therapy, and clinical trials may also be recommended for both types of cancer.

Prognosis

The prognosis for both mesothelioma and small cell lung cancer can be poor, especially if the cancer is detected in its advanced stages. However, mesothelioma usually has a worse prognosis than small cell lung cancer, as it is often diagnosed at a later stage and is more aggressive.

FAQs

1. Is mesothelioma only caused by asbestos?

Yes, mesothelioma is almost always caused by exposure to asbestos.

2. Can only smokers get small cell lung cancer?

No, although smoking is the most common cause of small cell lung cancer, non-smokers can also develop this type of cancer.

3. Can mesothelioma be cured?

There is no cure for mesothelioma, but treatment can help manage symptoms and prolong life.

4. How is small cell lung cancer usually treated?

Small cell lung cancer is usually treated with chemotherapy and radiation therapy.

5. What is the survival rate for mesothelioma?

The survival rate for mesothelioma depends on several factors, such as stage of cancer, age, and overall health. However, the average survival rate is approximately 12 to 21 months.

6. What is the most common symptom of small cell lung cancer?

The most common symptom of small cell lung cancer is chest pain.

7. Can both mesothelioma and small cell lung cancer be caused by smoking?

No, mesothelioma is almost always caused by exposure to asbestos, whereas small cell lung cancer is commonly associated with smoking.

Conclusion

Mesothelioma and small cell lung cancer are two types of lung cancer that are often misdiagnosed due to their similar symptoms. Although both types of cancer are associated with lungs, the causes, symptoms, treatment, and prognosis differ significantly. Therefore, it is essential to seek proper medical attention to determine the type of cancer and its stage. Early detection and treatment can increase the chances of survival and help manage symptoms.
