How common is mesothelioma?

Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. About 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.

There are three common forms of mesothelioma:

1. Pleural Mesothelioma is the most common form of Mesothelioma. It starts in the chest cavity (after breathing the particles) before spreading to other areas.

2. Peritoneal Mesothelioma starts in the abdomen (after swallowing the particles) and accounts for about 10-20% of Mesothelioma patients.

3. Pericardial Mesothelioma is the rarest form of Mesothelioma. It starts in the cavity that surrounds the heart.
