Risk Factors Genetics play a definite role. If your brother or sister had MM then your risk increases dramatically. Interestingly, the highest-risk occupations are indoors ones, like being a lawyer or dentist. This contrasts with BCC and SCC discussed earlier. All age groups are affected.
More aggressive melanomas arise in the over-fifty set.
The answer is no. MM has an interesting distribution. In women, the most common location is the upper legs. In men, it is the back. Unfortunately a significant number of MMs develop in odd locations like the scalp, so the location cannot be relied on for diagnosis.
