A Global Perspective The incidence of both non-melanoma and melanoma skin cancers has been increasing over recent decades Between two to three million non-melanoma skin cancers and 132,000 melanoma skin cancers occur globally each year One in every three cancers diagnosed is a skin cancer Sun Smart Saskatchewan 50 May 2011

Survival Rates for Melanoma The five-year survival rate represents persons who are living five years after diagnosis, whether disease-free, in remission or under treatment American Cancer Society estimates: o 5-year localized survival rate melanoma: 99% o 5-year distant spread survival rate melanoma: 16% o 5-year overall survival rate melanoma: 91% Estimated five-year relative survival rate in Canada is 90% o 87% for men & 93% for women Sun Smart Saskatchewan 53 May 2011

Summary Both sexes combined, the age-standardized incidence rate of melanoma is lower in Saskatchewan than the Canadian population over the time period of 1998 to 2005 SK males: the trend has been lower than the Canadian male population; however, rates are now increasing SK females: the trend has been higher than the Canadian female population; however, rates are now decreasing Age-standardized incidence rates of melanoma and non-melanoma (BCC, SCC) skin cancers are higher in males than females Sun Smart Saskatchewan 54 May 2011

Sun Smart Saskatchewan Established in June 2009 Vision – aware and engaged communities throughout Saskatchewan actively preventing skin cancer Create awareness of the risk for skin cancer from ultraviolet radiation exposure Encourage other organizations, groups and individuals to increase skin cancer prevention efforts Sun Smart Saskatchewan 55 May 2011
