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.

Treatment

Treatment for small cell lung cancer varies depending on the stage of the cancer, how far it has spread, and overall health. It often involves chemotherapy, immunotherapy, and radiotherapy.

Prognosis and response to treatment

Prognosis describes the likely outcome of the disease and response to treatment covers how treatment is affecting the cancer and the person receiving it.

Side effects

Side effects from treatment for small cell lung cancer vary depending on the type of treatment. Many are short-lived, and your healthcare team can help you manage them.

Remission and relapse

Remission and relapse describe how small cell lung cancer behaves after treatment. NED means the cancer is no longer detectable, and relapse refers to the cancer returning or progressing.

Caregiving and support

Being a caregiver to someone with lung cancer involves supporting them with everyday activities. Caregivers can access support to look after their own health and wellbeing.
