A guide on Melanoma covering signs and symptoms, prevention & treatment.
The primary cause of melanoma is ultraviolet light (UV) exposure in those with low levels of the skin pigment melanin.[2][7] The UV light may be from the sun or other sources, such as tanning devices.[2] Those with many moles, a history of affected family members and poor immune function are at greater risk.[1] A number of rare genetic conditions such as xeroderma pigmentosum also increase the risk.[8] Diagnosis is by biopsy and analysis of any skin lesion that has signs of being potentially cancerous.[1]
