early detection of skin cancer saves lives
asymmetry. one side of the mole doesn’t match the other side.
border. the edges of the mole are ragged or blurred.
colour. the colour of the mole is not the same, with different shades of brown or black — red, white and blue can also appear.
diameter. the mole is larger than six millimetres (1/4 inch) — about the size of a pencil eraser, or you notice growth.
evolution. a change in the size, shape, or colour, or symptoms, like itching tenderness, or bleeding.
most skin cancers that are found and removed early are almost always curable — treatment for melanoma can also be highly successful.
increased diagnosis of melanoma — but no longer a ‘death sentence’
a recent population-based
study in frontiers in medicine found that the incidence of melanoma is rising, with canadians living in southern and coastal parts of the country have a greater risk of developing the cancer.
study author dr. ivan litvinov, assistant professor in the department of medicine at mcgill university,
told ctv news that melanoma is more common than all other cancers combined. out of 80,000 skin cancer diagnoses per year in canada, 8,000 are melanomas.
“every hour and six minutes, someone is being diagnosed with melanoma,” he said
the research team found that in the early 2000s melanoma accounted for 12 cases per 100,000 per year — today, the national average is 20.75 cases per 100,000. the team also discovered that melanoma affects men and women differently, occurring on the head and trunk of the body for men, and mostly on the legs and arms for women.
“we do know that when people are exposed to sun, there’s a natural release of endorphins and sun-seekers are really addicted to this,” litvinov told ctv. “in today’s world, that really translates into a higher number of skin cancer, melanomas, photo aging, wrinkles of the skin. we actually want people to go out and enjoy the outdoors to the full, full potential. just don’t get a tan.”
