This tutorial walks you through everything you need to know about mesothelioma. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.
We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.
The tissue that lines your lungs, stomach, heart, and other organs is called mesothelium. Mesothelioma, also known as malignant mesothelioma, is cancer of that tissue. It usually starts in the lungs, but can also start in the abdomen or other organs.
Malignant mesothelioma is rare but serious. Most people who get it have worked or lived in places where they inhaled or swallowed asbestos particles. After being exposed to asbestos, it usually takes a long time for the disease to form.
Symptoms include:
Trouble breathing
Cough
Pain under the rib cage
Pain, swelling, or lumps in the abdomen
Weight loss for no known reason
Blood clots
Constipation
Fatigue
Sometimes it is hard to tell the difference between malignant mesothelioma and lung cancer. To find out if you have mesothelioma, your health care provider will likely use a physical exam, imaging tests, and a biopsy.
Malignant mesothelioma is often found when it is advanced. This makes it harder to treat. Treatment options may include:
Surgery
Radiation therapy
Chemotherapy
Immunotherapy
Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells
