I keep seeing commercials for these body scans. The commercial starts with a lady climbing a mountain of cigarettes and goes on to say that after you quit get a body scan. It makes sense that you would want to catch lung cancer early but I also know better than to put too much stock into a commercial. Has anyone gotten a scan like this? If so, how long after your quit did you get one? I plan on asking my doctor when I go in to see him soon but was wondering if any of you had opinions on them.
