Moles on the facial skin unnoticed may give rise to fatal skin disease known as Skin Cancer Face. Over exposure to the sun is supposed to be the main cause for the facial cancer. The UVA and UVB of the ultraviolet rays of the sun activate the oncogenes, malignant genes that start cancer. Heredity, toxic chemicals and exposure to radiation can also cause facial skin cancer. Generally warts or moles grow on the skin normally but those who are larger than normal shape and with a varied color are considered to be malignant. Aging and sun damage gives rise to facial skin cancer that looks like scaly patches which are red in color.
