How to prevent melanoma
Limit your exposure to the sun.
Melanoma begins in your body's melanocytes (the cells responsible for producing your body's pigment or color). Ultraviolet rays from the sun interact with these melanocytes, causing them to produce a dark protective pigment.
If your melanocytes are overexposed to ultraviolet rays, melanoma can begin to form. Malignant tumors are a result of cumulative cellular effects of uv light and inability of skin to mount a defense to it.
