It’s estimated that smoking is responsible for 30% of all cancer deaths in Canada and is related to more than 85% of lung cancer cases.
The more you smoke and the longer you smoke, the more you increase your risk of developing lung cancer. In fact, any smoking at all may cause lung damage over time.
Quitting isn't easy but it's worth it. Within 10 years of quitting, an ex-smoker’s overall risk of dying from lung cancer is cut in half. And your risk of these cancers goes down – mouth, throat, larynx, esophagus, bladder, kidney, pancreas and cervix.
