What percentage of melanoma are nodular?

How quickly does nodular melanoma spread?

How long can nodular melanoma go undiagnosed?

The duration of lesions before diagnosis is relatively short, ranging from a few months to 2 years [4]. Nodular melanoma often presents as an expanding darkly pigmented cutaneous nodular lesion, usually found on the sun-exposed areas of the skin, with far fewer such lesions occurring in covered areas.

How do you tell if you have nodular melanoma?

  1. Larger size than most moles – >6 mm and often a centimetre or more in diameter at diagnosis.
  2. Dome-shaped, often symmetrical firm lump.
  3. Single colour or variable pigmentation – most often black, red or skin coloured.
  4. Smooth, rough, crusted or warty surface.

Are nodular melanomas itchy?

Some melanomas itch. The “E” in the ABCDE rule of melanoma is for “Evolving,” which means that something about the mole changes. New itching or tenderness falls under “Evolving.” So does a change in the size, shape, color or elevation of the mole. A melanoma may also begin to bleed or crust over.

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma.
