Melanoma occurs in the melanocytes, i.e. the cells that produce melanin. Typically, these cells develop in a controlled way. The healthy cells push the old cells towards the skin surface where they eventually die. But when the DNA of the melanocytes changes, they may begin to grow uncontrollably, forming a mass of cancerous cells. 2. What exactly causes this change in the DNA is not very clear. Most researchers attribute it to be a combination of factors, including genetic and environmental factors. 3. Most doctors believe that too much exposure to the sun’s harmful UV rays is among the leading causes of melanoma.
