I'm writing a 5 para for science ab skin cancer. i have a lot of info but i am having trouble wording it. how should i paraphrase this? "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 tumors."
