What is Epithelioid Mesothelioma: Understanding the Most Common Form of Mesothelioma

Rate this post


When it comes to mesothelioma, a rare and aggressive form of cancer, understanding the specific types is crucial for effective diagnosis and treatment. One of the most common types is epithelioid mesothelioma. In this article, we will delve into the intricacies of this disease, from its definition to its symptoms, diagnosis, and available treatment options.

Understanding Epithelioid Mesothelioma

Epithelioid mesothelioma is a subtype of mesothelioma that develops in the mesothelial cells lining the internal organs, primarily the lungs. It accounts for approximately 70% of all mesothelioma cases and is often associated with asbestos exposure. These cancerous cells can infiltrate the surrounding tissues and spread to other parts of the body.

Symptoms and Diagnosis

Detecting epithelioid mesothelioma in its early stages can significantly improve the chances of successful treatment. However, due to the non-specific nature of its symptoms, diagnosis can be challenging. Some common symptoms include persistent cough, shortness of breath, chest pain, fatigue, and unexplained weight loss.

To diagnose epithelioid mesothelioma, doctors may employ various techniques, including imaging tests such as X-rays, CT scans, and MRI scans. Additionally, a biopsy, which involves the extraction of a tissue sample for laboratory examination, is often necessary to confirm the presence of epithelioid mesothelioma.

Treatment Options

Once a diagnosis is confirmed, determining the most appropriate treatment plan for epithelioid mesothelioma becomes crucial. The choice of treatment depends on several factors, including the stage of the cancer, the patient’s overall health, and their personal preferences.

Treatment options for epithelioid mesothelioma may include surgery, chemotherapy, radiation therapy, and targeted therapy. Surgery aims to remove the tumor and affected tissues, while chemotherapy and radiation therapy target and destroy cancer cells. Targeted therapy, on the other hand, utilizes drugs that specifically target genetic mutations or abnormalities present in cancer cells.

Frequently Asked Questions about Epithelioid Mesothelioma

Q: What is the main cause of epithelioid mesothelioma?

Epithelioid mesothelioma is most commonly caused by exposure to asbestos, a mineral once widely used in construction, shipbuilding, and manufacturing industries. Inhalation of asbestos fibers can lead to the development of mesothelioma over time.

Q: Is epithelioid mesothelioma curable?

While there is currently no known cure for epithelioid mesothelioma, early detection and aggressive treatment can significantly improve a patient’s prognosis and quality of life.

Q: Can I develop epithelioid mesothelioma without asbestos exposure?

Although the majority of epithelioid mesothelioma cases are linked to asbestos exposure, there have been rare instances where individuals who were not exposed to asbestos developed the disease. However, such cases are extremely uncommon.

Q: Are there any alternative treatments for epithelioid mesothelioma?

While alternative treatments may be explored, it is crucial to consult with a qualified medical professional. They can provide guidance on complementary therapies that can be used alongside conventional treatments to manage symptoms and improve overall well-being.


In conclusion, epithelioid mesothelioma is the most common form of mesothelioma, primarily affecting the lungs. Its symptoms can be challenging to diagnose accurately, and early detection is key to improving treatment outcomes. With various treatment options available, tailored approaches can be designed to fit each patient’s specific needs. If you suspect you may have epithelioid mesothelioma or have been exposed to asbestos, it is important to seek medical advice promptly. By staying informed and proactive, we can contribute to better outcomes for those affected by this disease.
