These are of three main types, squamous-cell skin cancer, basal-cell skin cancer and melanoma. Melanomas are aggressive cancers. Symptoms vary as per the underlying cancer and may include a painless raised area of skin, a color or shape change in a mole, etc. More than 90% of all cases of skin cancer are caused due to an exposure to ultraviolet radiation from the sun.
