Small cell lung cancer

This is caused by small round cells that form fleshy lumps, usually in the larger airways and is very rare in non-smokers. This type of lung cancer cell divides and grows very quickly and has often spread to the lymph nodes and/or other organs in the body by the time it is diagnosed.

It is known to be more responsive to chemotherapy and radiotherapy than non-small cell lung cancers and may reoccur. You will attend regular check-ups after treatment is complete to ensure any reoccurrence is spotted quickly.

Other types of lung cancer

The diagnosis and treatment of lung cancer can be complicated.
