Do you really need another reason to stop smoking? If you're a male smoker closing in on retirement, check out a study published in JAMA last week concluding that smoking increases all-cause, prostate cancer specific, and cardiovascular mortality. One has to have quit for at least 10 years for those mortality figures to drop back to baseline non-smokers' levels.
Just how strong is the data? Well, the authors followed 5,366 men from the Health Professionals Follow Up Study who'd been diagnosed w/prostate cancer. This prospective observational study included those diagnosed between 1986 & 2006 so the statistics are reasonable and random chance is very unlikely to account for these findings.
The bottom line for you & me? Don't smoke! And if you do, now's the day to quit. If you need help, ask your family doc. Good luck! And don't give up!
