What is lung cancer?
Lung cancer is abnormal cell growth in one or both of a person’s lungs. The lungs are made up of different cells types. This results in there being different types of lung cancer. Most of these types can be grouped into the more common non-small cell lung cancer, or NSCLC, and the less common small cell lung cancer, or SCLC. Lung cancer is often diagnosed by a biopsy through the skin into the tumour, or through a procedure known as a bronchoscopy. This is when a flexible tube is inserted into a person’s lungs and a tissue sample taken. This sample is looked at under a microscope for signs of cancer.
