What is small cell lung cancer?

Small cell lung cancer (SCLC) usually starts in cells in the lungs that are involved in air and blood flow, and it can spread faster than other types of lung cancer. Smoking, or exposure to tobacco smoke, is the most common cause.

Symptoms

Symptoms of small cell lung cancer can develop quickly and can affect different parts of the body, not just the lungs.

Diagnosis

Diagnosing small cell lung cancer involves imaging tests, biopsies, and laboratory tests. These tests look for abnormalities, check whether there are cancer cells in the lungs and airways, and determine if the cancer has spread.

Staging

Staging describes how far small cell lung cancer has spread and helps guide treatment decisions. Doctors often use limited and extensive stages, and sometimes a more detailed system, to describe the cancer in greater depth.
