Most people are aware that the ultraviolet radiation from the sun causes the greatest risk for developing skin cancer. Less widely known however, is that tobacco use can triple your risk of developing squamous cell carcinoma, especially in women.
Exactly how tobacco smoke leads to skin cancer remains unclear. It's possible that one or more of the 4,000 chemicals found in cigarette smoke may act as a skin carcinogen (cancer-causing agent), either by direct contact with smoke (which may damage the DNA in skin cells) or by being absorbed by the lungs into the bloodstream.
Regardless, skin cancer spreads quickly and can cause permanent disfigurement. This is one more good reason for people to stop smoking or never to start. But, don't just take my word for it.
