Over the last 30 years cases of melanoma – a common form of skin cancer – have been on the rise. Risk factors for melanoma include over-exposure to sun, indoor tanning beds and even family history. Now, researchers from Tel Aviv University have identified a trigger which leads to melanoma.
If caught early, melanoma can be removed and save a person’s life. Therefore, uncovering a trigger can lead to more successful removals of the cancer.
Research lead Carmit Levy explained that melanoma starts in the epidermis, or outer layer of the skin. He said if the cancer spreads to the lower layer, the dermis, it can eventually enter the bloodstream and spread to other parts of the body. “But before invading the dermis, melanoma cells surprisingly extend upward, then switch directions to invade,” said Levy.
