Exposure to sunlight can increase your risk of developing one or more of the three types of skin cancer. Keep an eye on skin lesions – and check with your doctor if you detect any change in them.

Take action:
Contact your doctor if a lesion: changes colour from light to dark or white to pale pink; changes shape and size; develops irregular, swollen ridges; peels, heals and peels again; forms an ulcer in the centre and doesn’t heal; or suddenly reappears. Note that most cancer lesions are not associated with bleeding, scab formation or pain.
