Skin cancer is the most common type of cancer in Canada. About 1 in 3 cancers diagnosed in Ontario are skin cancer.
Most types of skin cancer are caused by too much Ultraviolet (UV) radiation from the sun or other sources, like tanning beds.
A tan is your skin's response to the damage to skin cells by UV rays. There's no such thing as a safe tan. Protecting the skin from UV rays can prevent most cases of skin cancer.
