Melanoma occurs when skin is damaged and the DNA fails to repair. During the process of producing melanin cells, something goes wrong which triggers mutations in those skin cells. These mutated skin cells can multiply rapidly and form malignant tumours.
Skin cells ordinarily develop in a contained and calm matter. New healthy cells form under your skin’s surface and push the older cells out, where they eventually die and fall off – this happens constantly to every one of us. As mentioned before, some cells develop DNA damage which triggers the production of cells that are abnormal and dangerous.
Unfortunately, it is unclear exactly what damages DNA in skin cells and how it leads to melanoma, however, it is very likely a combination of multiple factors. These factors include exposure to ultraviolet light, skin type, personal & family history and more.
This page will go into more detail about the multiple factors that cause melanoma.
