NY Times – Cutting Your Lung Cancer Risk

If you stop smoking, does your increased cancer risk eventually return to zero? Can eating carrots protect against lung cancer? Should a recovering cancer patient test for radon, and are there other risks to be aware of in the home? Is there an estrogen-lung cancer link? These are among the questions readers recently posed by readers of the Consults blog. Dr. Derek Raghavan, director of the Taussig Cancer Institute at the Cleveland Clinic, responds.

Stopping Smoking? Foods to Fight Cancer?

Q.In college, someone told me that they’d heard that if you smoked in your younger days, and gave it up by the time you turn 30, all of the damage incurred earlier could reverse itself. Is there any truth in this?

Also, I read somewhere that consuming carrots was beneficial for protection against lung cancer. Is there any truth in this? If not, are there any foods that might help?
