Diagnose Mesothelioma: Early Detection is Key


Welcome to our guide to diagnosing mesothelioma, a rare and aggressive cancer caused by asbestos exposure. Mesothelioma can be incredibly difficult to diagnose, as its symptoms often mimic those of other, less serious conditions. However, early detection is crucial for effective treatment and improved prognosis. In this article, we will explore the diagnostic process for mesothelioma, the tools and tests used to identify the disease, and what to expect after receiving a diagnosis.

What is Mesothelioma?

Mesothelioma is a type of cancer that develops in the protective lining of organs, most commonly the lungs, abdomen, or heart. The primary cause of mesothelioma is exposure to asbestos, a naturally occurring mineral that was widely used in construction, manufacturing, and other industries until the 1970s.

When asbestos fibers are inhaled or ingested, they can become lodged in the lining of the lungs or abdomen, causing inflammation and scarring over time. This can eventually lead to the development of mesothelioma, which can take decades to manifest.

It is estimated that around 3,000 new cases of mesothelioma are diagnosed in the United States each year, with men over the age of 65 being most at risk.

What are the Symptoms of Mesothelioma?

As mentioned above, mesothelioma symptoms can be vague and easily mistaken for other conditions. Some common symptoms include:

Symptom Description
Shortness of breath Difficulty breathing or catching your breath
Chest pain Pain in the chest or rib cage
Coughing Persistent cough or coughing up blood
Abdominal pain Pain or swelling in the abdomen
Unexplained weight loss Sudden weight loss without a clear cause

If you are experiencing any of these symptoms, especially if you have a history of asbestos exposure, it is important to see a doctor as soon as possible.

How is Mesothelioma Diagnosed?

Diagnosing mesothelioma can be a complex and multi-step process, often involving a range of tests and imaging studies. Here are some common diagnostic tools used to identify mesothelioma:

Medical History and Physical Exam

Your doctor will start by taking your medical history, including any known exposure to asbestos, and performing a physical exam.


X-rays can help detect abnormalities in the lungs or chest cavity, such as fluid buildup or thickening of the lining.

CT Scans

CT scans use multiple X-rays to create detailed images of the inside of the body, which can help identify tumors or other abnormalities.

MRI Scans

MRI scans use magnetic fields and radio waves to create images of the body’s soft tissues, including organs and blood vessels. This can provide a clearer picture of the extent and location of any tumors or growths.

PET Scans

PET scans use a radioactive tracer to highlight areas of the body with high metabolic activity, such as cancer cells. This can help identify the spread of mesothelioma to other parts of the body.


A biopsy involves taking a small tissue sample for examination under a microscope. This is the most definitive way to diagnose mesothelioma, as it allows doctors to examine the cells themselves and determine the type and stage of the cancer.


What is the Prognosis for Mesothelioma?

The prognosis for mesothelioma is generally poor, with most patients surviving less than two years after diagnosis. However, early detection and aggressive treatment can improve the chances of survival.

What are the Treatment Options for Mesothelioma?

Treatment for mesothelioma typically involves a combination of surgery, radiation therapy, and chemotherapy. The specific approach will depend on the type and stage of the cancer, as well as the patient’s overall health.

Can Mesothelioma be Prevented?

The only way to prevent mesothelioma is to avoid exposure to asbestos. This may involve taking precautions in certain occupations or industries, or by avoiding buildings or products that may contain asbestos.

What Should I Do if I Have Been Exposed to Asbestos?

If you believe you have been exposed to asbestos, it is important to notify your doctor and undergo regular monitoring for signs of mesothelioma or other asbestos-related diseases.

How Long Does Mesothelioma Take to Develop?

Mesothelioma can take anywhere from 10 to 50 years to develop, with most diagnoses occurring 20-40 years after exposure to asbestos.

Is Mesothelioma Always Caused by Asbestos Exposure?

While asbestos exposure is the primary cause of mesothelioma, other factors such as radiation exposure or genetic predisposition may also play a role.

Can Mesothelioma Spread to Other Parts of the Body?

Yes, mesothelioma can spread to other organs and tissues in the body, including the lymph nodes, liver, and bones.

What is the Most Common Form of Mesothelioma?

The most common form of mesothelioma is pleural mesothelioma, which affects the lining of the lungs.

What are Some Risk Factors for Mesothelioma?

Some common risk factors for mesothelioma include exposure to asbestos, age (most cases are diagnosed in people over 65), and gender (men are more likely to develop mesothelioma than women).

Can Mesothelioma be Inherited?

No, mesothelioma is not an inherited condition. However, certain genetic mutations may increase the risk of developing mesothelioma after exposure to asbestos.

What Should I Expect During Mesothelioma Treatment?

Mesothelioma treatment can be intensive and may involve multiple rounds of surgery, radiation, and chemotherapy. Your healthcare team will work with you to develop a personalized treatment plan that takes into account your overall health and preferences.

What Support is Available for Mesothelioma Patients and their Families?

Many resources are available for mesothelioma patients and their families, including support groups, counseling services, and financial assistance programs. Your healthcare team can help connect you with these resources.

What is the Cost of Mesothelioma Treatment?

The cost of mesothelioma treatment can vary widely depending on the type and stage of the cancer, as well as the specific treatments recommended. Insurance coverage and financial assistance programs may be available to offset some of these costs.

How Can I Stay Healthy After Mesothelioma Treatment?

After completing mesothelioma treatment, it is important to maintain a healthy lifestyle and continue monitoring for signs of recurrence. This may involve regular check-ups with your doctor, as well as making healthy choices regarding diet, exercise, and stress management.


In conclusion, diagnosing mesothelioma can be a challenging and complex process, but early detection is crucial for effective treatment and improved prognosis. If you are experiencing symptoms of mesothelioma, particularly if you have a history of asbestos exposure, it is important to seek medical attention as soon as possible.

While mesothelioma can be a devastating diagnosis, there are treatment options available, as well as resources and support for patients and their families. By staying informed and proactive about your health, you can take an active role in managing this condition and living a fulfilling life.
