Lung
Cancers

Lung cancer can either arise directly from lung tissue or as a result of metastasis from another part of the body. There are two main types of primary tumour described as either small-cell or non-small-cell lung carcinomas. The major risk factor for cancer is smoking. Once a cancer is identified it is staged using scans such as a CT scan and a sample of tissue from a biopsy is taken. Cancers may be treated surgically by removing the tumour, the use of radiotherapy, chemotherapy or a combination, or with the aim of symptom control. Lung cancer screening is being recommended in the United States for high-risk populations.
