What Is Melanoma?

A serious form of skin cancer, melanoma forms in the melanocytes, which are the skin’s pigment cells. When melanocytes cluster together in groups, a mole is formed. Melanocytes can potentially form a cancer when exposed to recurring ultraviolet damage, the most common of which is sun exposure.

There are three layers in our skin – the epidermis is the outer layer, the dermis is the next layer and the hypodermis is the deepest layer. Melanomas are ranked by levels, which refers to the cancer’s depth of skin penetration. An in situ or Level 1 melanoma is located in the epidermis, Levels II, III and IV melanoma are found in the dermis and Level V melanoma occurs in the hypodermis.

Melanoma is the most aggressive form of skin cancer and can grow rapidly when left untreated. For this reason, it’s crucial to consult your doctor or dermatologist about any lesions which cause concern.

“I was 31 when one day I noticed a mole on my stomach which had a new black dot on it. My mum was visiting so I showed her and she had this look on her face like she knew it wasn’t good.”
