Skin cancer is the most commonly diagnosed cancer in Ontario, being responsible for one third of all new cases of cancer. There is substantial evidence that exposure to ultraviolet radiation (UV rays) from the sun causes skin cancer. Artificial tanning equipment is also a source of UV rays and evidence supports it creates increased risk of skin cancer. Some people may be at greater risk for skin cancer because of personal risk factors (fair skin, hair and eyes; history of sunburns as a child, spend long periods of time out of doors), but everyone needs to take precautions when it comes to the sun.
