Prostate cancer patients who smoke are more likely to have tumors return, spread to other parts of the body, and become fatal than nonsmokers, a new study suggests.
Researchers examined data from previous studies with a total of 22,549 men with prostate cancer that hadn’t spread to other parts of the body. The cancers were treated with either surgery or radiation.
Overall, nearly one in five were current smokers. The rest were either former smokers or had never smoked.
