I recently quit smoking. I hadn't smoked for long, just a few months. Does the risk of getting lung cancer decrease after you quit smoking?

The single best way to prevent lung cancer is not to smoke. If you smoke, quit for good as soon as possible. Not long after you quit, your risk of lung cancer begins to drop. After 10 years of not smoking, the risk of lung cancer is about 50% lower compared to continued smokers and continues to decrease with time.

stop smoking however, I dont believe you are ever not at risk. my mother smoked for 30 years quit 19 years ago. has stage one lung cancer. upper lobe removed size of a orange. doing fine does not need chemo. but 19 years later give me a break. if you smoke you should keep a very good record of your health and notice any changes going on.

there are also some people who dies out of lung cancer and has never smoked in her life! how will you explain that? this means that lung cancer is not provoked by smoking! but smoking can act as a catalyst in processing the cancer and make it much more dangerous to the health!
