Synonyms for melanocarcinoma or melanoma can include malignant melanoma, cutaneous melanoma, and metastatic melanoma. Other related terms may include nevus, mole, dermal melanoma, and superficial spreading melanoma. Regardless of the terminology used, melanoma is a serious form of skin cancer that can spread to other parts of the body if not caught and treated early. Regular skin exams and sun protection are essential in preventing this type of cancer.
