Lung cancer in Canada
Lung cancer develops in the cells of the lungs. Changes in these cells may lead to benign tumours (non-cancerous), but when cells no longer behave normally, they may cause malignant tumours (cancer). Cancer starting in the lung cells is known as primary lung cancer. Cancers that start in other parts of the body can spread to the lungs (lung metastasis), but they are not treated in the same way as primary lung cancers.
