Living with Small cell lung carcinoma

A fast-growing type of lung cancer, most often found in older adults with long-term tobacco exposure.

Understanding Small cell lung carcinoma

Small cell lung carcinoma (SCLC) is a type of lung cancer that is highly aggressive and spreads quickly to other parts of the body.

It accounts for 10 to 15 percent of lung cancer cases. It usually appears as a large mass in the center of the chest. It can also cause problems with the nervous and endocrine (hormone) systems. It is most common in older people with a history of long-term tobacco exposure.
