Only 35% of melanoma excisions comply with guidelines
Most melanomas are overtreated or undertreated in terms of excision, with only one-third excised according to surgical margin guidelines, a NSW study suggests.
A review of 1700 histologically confirmed melanomas excised by more than 1000 doctors, including GPs, found that 45% were overtreated — particularly in situ and thin (0-1.5mm Breslow) invasive melanomas.
