What increases my risk for stage 1 melanoma?

There are several factors, both genetic and environmental, that may put you at risk for stage 1 melanoma. Obviously, if you have been diagnosed with stage 0 melanoma and leave the growth untreated, you are at a very high risk for developing stage 1 melanoma. In general, if a family member has had melanoma, you are at a higher risk for the disease. Also, you are at a greater risk for melanoma if you have light hair and skin since your skin has less pigment to protect from harmful ultraviolet rays. Other genetic risk factors include having more than 50 moles, having any irregular moles, and having a weakened immune system. Environmental risk factors may also affect the development of stage 1 melanoma. If you have had a lot of sunburns, especially as a child, you are at greater risk for melanoma. Increased sun exposure in general also increases your risk.
