MALIGNANT MELANOMA
(SKIN CANCER)
Among skin diseases, melanoma is the most frequent cause of death, and the incidence has increased about 4% per year since 1973. National incidence rates were12.5 per 100,000 in 1994. The lifetime risk of developing this cancer is estimated to be 1:75 by the end of the century. (9) Vanderburgh county rates were 7.76 in 1994. The 5-year relative survival rate for malignant melanoma is 88% nationally. The relative rate of survival is not known for Vanderburgh County, however the observed survival rate is 72.2. The observed rate reflects no consideration for normal life expectancy and is therefore a higher mortality than the relative rate. Melanoma affects a relatively young patient population; the median age at diagnosis is 45 years.
