Melanoma, the most serious type of skin cancer, develops in the cells (melanocytes) that produce melanin, the pigment that gives color to the skin. Melanomas can also form in the eyes and rarely in internal organs such as the intestine. The exact cause of all melanomas is not clear, but exposure to the sun's ultraviolet (UV) rays, lamps, and sunbeds increase the risk of developing melanoma. Limiting exposure to UV rays can help reduce the risk of melanoma. The risk of melanoma appears to be increasing among those under the age of 40, especially in women. Knowing the warning signs of skin cancer can help detect and treat cancer changes before cancer spreads. Melanomas can be treated successfully if they are detected early.
Identifying signs of melanoma are following
- Changes in the shape or color of existing moles.
- New mole appearance which increased in size.
- The appearance of a new lump anywhere on the skin.
- Mole having the itch, ulcerate or bleed
The best treatment option is removed by surgery. But if it is malignant and has spread to others part so immunotherapy, chemotherapy or radiotherapy may help to improve the survival rate.
