Melanoma is a cancer of the skin or mucous that can take different forms. The cancer can occur suddenly on a skin that was previously normal, or more rarely in a preexisting mole. Therefore, it is very important to consult a dermatologist as quickly as possible if you have a mole that undergoes a change in its:
- surface texture
- feeling (becomes painful or sensitive)
In addition, tell your dermatologist about any abnormal change in your skin. Like any cancer, melanoma must be detected and treated early for a better prognosis. Earlier the tumor is diagnosed, more chance you have to survive.
In early melanoma, you can observe a change in an existing mole or colored skin growth of a few millimeters. Unlike a regular skin lesion, a spot of melanoma is often asymmetrical and has an irregular border. After months or years, depending on the type of melanoma you have, the spot/mole evolves and undergoes changes in its size, shape, contour and color.
In addition, melanoma is often accompanied by the following dermal signs:
- changing the area surrounding the lesion
- presence of a growth or nodule
- extension of the lesion (it grows deeper into the skin)
- Itching – often associated with bleeding.
