Things About Lung Cancer Doctors Wish You Knew
Your risk is dose-dependent
The more you smoke (or did in the past), the greater the risk of lung cancer. “Although quitting is the best way to decrease the risk of being diagnosed with lung cancer, it does not make the risks go away,” Dr. Sands says. Fifty percent of those diagnosed with lung cancer are former smokers, he says. But this doesn’t mean you shouldn’t bother quitting. “The risk decreases the longer the person has refrained from smoking,” he says. According to Harvard Medical School, a former smoker’s lung cancer risk is cut by 50 percent in ten years, but is still elevated after 15 years.
