Lung Cancer
Lung cancer, also known as lung carcinoma, is the uncontrolled growth of abnormal cells in one or both lungs. It most often occurs in people who smoke. As lung cancer grows, abnormal cells can form tumours and interfere with the functioning of the lung, which provides oxygen to the body via blood. Nowadays, it is increasingly being seen that non smokers come to my OPD after being diagnosed as lung cancer. The possible explanation can be second hand smoke, and pollution plays a major part in it. As lung cancer grows, abnormal cells can form tumours and interfere with the functioning of the lung, which provides oxygen to the body via blood.
