When I first read the word mesothelioma, I thought it was a medicine brand. Didn’t know it’s a form of cancer:
Mesothelioma is a form of cancer that is almost always caused by exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body’s internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart, the pericardium (a sac that surrounds the heart) or tunica vaginalis.
I guess, nowadays, we should know different forms of cancer and make ourselves aware of the signs and symptoms.
