Malignant melanoma is a highly dangerous form of skin cancer, in which the DNA of the skin cell is damaged. This prompts mutations, which causes the skin cells to rapidly multiply, thereby causing malignant tumor. The tumor develops in the pigment producing melanocytes, and can also develop in moles that are present in the basal layer of the epidermis, similar to melanosomes. This condition is caused due to intense, occasional exposure to UV radiations (sunlight) and also through the genetic variations, which cause damage to the DNA of the skin cells. Change in the shape and color of the moles, and appearance of new lumps on the skin are the symptoms of early stages.
HOW IS MALIGNANT MELANOMA DIAGNOSED?
A person who has more than 100 moles is at a greater risk of melanoma.
