Staging of Melanoma

Following a diagnosis of melanoma, your doctor will determine its current stage. Staging is a system of classifying the severity of the disease. It is very a important factor in optimally treating your melanoma.

Stage 1
Tumors that are 0-2.0 mm without ulceration or 0-1.0 with ulceration. Surgical excision is highly effective (90% cure rate for lesions < 1 mm).
