Skin Cancer is a tumour that grows from skin cells, and repeated severe sunburns or long-term exposure to the sun.
Reference Definition by Skincancer.org: Skin Cancer is the uncontrolled growth of abnormal skin cells. It occurs when unrepaired DNA damage to skin cells (most often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations, or genetic defects, that lead the skin cells to multiply rapidly and form malignant tumours.
