Skin cancer happens when the skin does not react well to the ultraviolet rays of the sun. This leads to slight aberrations on the skin. There is a slight change of color in the affected skin area. This may be misleading however and is not a final warning of presence of skin cancer.
There would be blemishes on different parts of the body that are exposed to sun’s rays. Hands, face, and neck are probable examples. Skin cancer also occurs in the covered parts. There is a chain of itchiness which is quite irritating at times. There would be an occurrence of moles around the body, mainly on the back. The areas around the mole would change color fast. That is a very stern warning sign.
Skin cancer is of three types: Basal Cell Carcinoma, Squamous Cell Carcinoma and Melanoma. The names itself suggest that the intensity deepens from the first to third. The last one is practically incurable and the tumors appear and burst in the final conjunction. The best part of skin cancer is that it is external and gives certain idea even to the layman. He or she may head to the doctor then to get the diagnosis done.
