A small but significant number of skin cancers are malignant melanomas. Malignant melanoma is a highly aggressive cancer that tends to spread to other parts of the body. These cancers may be fatal if not treated early
Skin cancer may initially appear as a nodule, rash, or irregular patch on the surface of the skin. These spots may be raised and may ooze or bleed easily. As cancer grows, the size or shape of the visible skin mass may change and cancer may grow into deeper layers of the skin.
