Melanoma skin cancer






Doctors sometimes use the term lesion to describe a finding on the skin. This means an area of skin that looks different from the surrounding area.
The following 2 examples contain 2 pictures. The first picture in each example is taken from a distance. The second picture from each example is a close up of the melanoma.

Symptoms include changes to a mole, freckle or normal patch of skin. Doctors use a checklist of signs to look out for. But it helps to know what your skin normally looks like.
You may be referred to a specialist if you have symptoms that could be due to melanoma skin cancer. This might be an urgent suspected cancer referral.
The risk of developing melanoma skin cancer depends on many things including how much ultraviolet radiation you get from the sun and your skin type.
Melanoma skin cancer starts in skin cells called melanocytes. You can get it anywhere on your skin including in a mole, on your palms, the soles of your feet and under your nails.
The stage of a melanoma skin cancer tells you how deeply it has grown down into the skin. It also tells you if it has spread elsewhere in your body and how far.
