What are the Risk Factors for Smoking?

The biggest risk factor for lung cancer is smoking cigarettes. According to the experts, when you inhale cigarette smoke, you intake carcinogens directly into your lungs. It causes tissue changes there that eventually result in cancer.

Exposure to Secondhand Smoke

Second-hand smoke or passive smoke is the one that you inhale from the environment. Even if you do not smoke, if you are in a place where other people smoke, it can cause changes in your lungs, leading to lung cancer.

Radiation Therapy

If you undergo radiation therapy for any other condition, you may develop lung cancer. It can happen because radiation can damage your cells. However, your healthcare provider will make a decision based on the risk versus benefit ratio.

Exposure to Radon Gas

Radon gas is produced upon the breakdown of uranium in soil, rock, and water naturally. It eventually becomes the part of the air we breathe. Therefore a long-term radon exposure can lead to lung cancer.

Exposure to the Carcinogens

If you work at a place where you get daily exposure to the carcinogens, such as asbestos, nickel, arsenic, and chromium, the risk of lung cancer increases for you. Moreover, if you are a smoker too, the risk doubles up for you.

Family History

Having a family history of lung cancer can put you at risk of it. If your mother, father, or sibling have had it, the risk for you increases.

Quit smoking as soon as possible. If you are unable to do that, you can seek professional help.
Avoid exposure to secondhand smoke.
Follow all the precautions if you work in an area where there are carcinogens.
