The total number of melanomas detected at Peninsula Skin Cancer Centre in 2019 was 369. This includes melanomas detected at Mornington and Frankston. Fortunately 98% of these melanomas were considered thin, less than 1mm deep, which means a wide excision is all that is required to treat that primary melanoma. All of these melanoma patients will require close surveillance for the next few years as they have an increased risk for another primary melanoma. The best surveillance method for high risk patients is mole mapping.
