Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. Normal lung tissue consists of cells programmed to reproduce and develop into healthy, well formed lungs. In lung cancer, abnormal cells reproduce rapidly and disrupt natural programming. Tumours then form and block healthy lung tissues, making it difficult for the lung to function properly.
There are two general types of lung cancer – small cell lung cancer and non-small cell lung cancer. Lung cancer can also spread to lymph nodes or other tissues in the chest, including the other lung, and other organs such as the bones, brain and liver.
These symptoms may be caused by a number of problems and may not indicate the presence of cancer, but if any of the above symptoms persists or is bothering you, do consult your doctor for advice.
Population screening for lung cancer is currently not recommended.
Treatment options for lung cancer range from surgery, radiation therapy to chemotherapy.
