There are several macroscopic (naked eye) features suggesting that a mole in the skin is likely to be a malignant melanoma rather than a benign melanocytic nevus. 1. change in size – any adult nevus > 6 mm is suspect (for reference a lead pencil diameter is 7 mm) and anything changing to > 10mm is more likely to be malignant than benign. 2. Below are the warnings and signs of cancerous moles and having a melanoma. the existing mole changes in color. a sign of skin cancer is detected when you notice your mole or wart is having different colors, like from brown to light brown or tan or black, actually combination of all. the existing mole changes in size and shape.
Ditto if you see a small notch or protrusion along the edge of a mole. c = color: moles featuring two to three different shades of brown should be looked at a bit suspiciously. moles colored blue. The first melanoma signs and symptoms often are: a change in an existing mole. the development of a new pigmented or unusual looking growth on the skin. melanoma doesn't always begin as a mole. it also can happen on otherwise healthy skin. melanomas symptoms can happen anywhere on the body. Melanoma, also referred to as malignant melanoma, is a potentially very serious skin cancer in which there is an uncontrolled growth of melanocytes ( pigment cells). normal melanocytes are found in the basal layer of the epidermis (outer layer of skin). melanocytes produce a protein called melanin, which protects skin cells by absorbing. About 30% of melanomas begin in existing moles, but the rest start in normal skin. this makes it especially important to pay attention to changes in your skin because the majority of melanomas don't start as moles. however, how many moles you have may help predict your skin’s risk for developing melanoma.
