What causes stage 3 melanoma?

Stage 3 melanoma is caused when melanoma progresses and has spread from the skin through the underlying tissue and into the lymph nodes closest to the melanoma. Though the specific cause of melanoma itself is unknown, it appears that melanoma develops when there are problems with the DNA that controls skin cells. In people with melanoma, DNA is damaged and causes an overgrowth of skin cells, which results in a cancerous melanoma. Although it's not proven that ultraviolet (UV) light causes melanoma, skin that is exposed to UVA and UVB radiation from sun exposure or tanning beds seems to be most vulnerable to damage.
