Every year, almost 2 Million people get diagnosed with lung cancer. Lung cancer is the leading cause of cancer deaths worldwide. Smoking causes the highest risk of lung cancer. Although some lung cancers occur in people who have never smoked as well. In fact, the risk of lung cancer is said to increase with the length of time and the number of cigarettes you have smoked.
What are the common symptoms of lung cancer?
Lung cancer may be present, even without any symptoms in the very early stages. Some of the signs and symptoms of lung cancer include:
What are the types of lung cancer?
Lung cancer is divided into two types based on how the cells in the tumor appear under the microscope. This includes Small cell lung cancer and Non-small cell lung cancer. Small cell lung cancers are less common and occur almost exclusively in heavy smokers. Most of the other types of lung cancer are grouped under non-small cell lung cancers. These include variants like squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.
How does smoking cause lung cancer?
Smoking damages the cells that line the inner side of the lungs. Cigarette smoke is full of cancer-causing agents and can alter the structure of these cells. At first, your body is able to repair the damage, but as the exposure progresses, the cells that line the lung become affected beyond repair. Over time, this leads to the formation of lung cancer.
Exposure to secondhand smoke can also do similar damage to your lungs. Previous radiation therapy, exposure to radon gas or asbestos, etc. are also considered to increase the risk of developing lung cancer.
