What is small cell lung cancer?
Clinical oncologist, Neil Bayman, explains what lung cancer is, the main types, risk factors, stages and common treatments available to you.
Lung cancer is the third most common cancer in the UK. About 47,000 people are diagnosed with it each year. Cancer that starts in the lung is called primary lung cancer.
There are two main types of primary lung cancer:
- non-small cell lung cancer (NSCLC)
- small cell lung cancer (SCLC).
Small cell lung cancer (SCLC) gets its name from how the cancer looks under a microscope. It makes up about 1 in 7 lung cancers (about 15%).

Causes of small cell lung cancer
Smoking tobacco is the cause of most lung cancers and the biggest risk factor. This includes smoking cigarettes, cigars and pipes. People who do not smoke can still develop lung cancer, but their risk is much lower.
If someone stops smoking, their risk of developing lung cancer gets lower over time. After about 15 years it is almost the same as a non-smoker.
Lung cancer is also more common in older people.
We have more information about the risk factors of lung cancer.

Diagnosis of small cell lung cancer
People may be diagnosed with small cell lung cancer after seeing their GP about their symptoms. If your GP thinks your symptoms could be caused by lung cancer, they will arrange tests to help make a diagnosis. These can include:
If these tests show anything abnormal, your GP will refer you to a chest specialist within 2 weeks. Sometimes they will do this before getting the result of the chest x-ray.
At the hospital, the specialist will explain any other tests you need. These may include:
-
PET-CT scan
-
Biopsy
Waiting for tests results can be a difficult time, we have more information that can help.

You may have the following tests:
-
Mediastinoscopy
-
Thoracoscopy

The language we use
We want everyone affected by cancer to feel our information is written for them.
We want our information to be as clear as possible. To do this, we try to:
- use plain English
- explain medical words
- use short sentences
- use illustrations to explain text
- structure the information clearly
- make sure important points are clear.
We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected.
