Pleural Mesothelioma

Receiving a pleural mesothelioma diagnosis can be a frightening and confusing time for families. Learn the need-to-know information that will help you treat and cope with this rare cancer.

Malignant pleural mesothelioma is a rare, aggressive cancer that develops in the thin layer of tissue surrounding the lungs known as the pleura. The disease is caused primarily by the inhalation of microscopic asbestos fibers. Once these fibers are inhaled, they can become lodged in the lining around the lungs. The fibers accumulate in the body, and cause cellular and genetic damage that can ultimately lead to cancer.

It's the most common of the four types of mesothelioma, accounting for about 75 percent of all cases diagnosed annually in the U.S. More than 2,000 people are diagnosed with this pleural cancer each year.

A majority of these cases are traced to occupational exposure to asbestos, which put factory workers, shipyard workers, mechanics and construction workers at the highest risk. Keep in mind, it can take anywhere from 10 to 50 years after exposure for the cancer to develop.
