Basically there are 3 types of skin cancer namely basal cell carcinoma, squamous cell carcinoma and malignant melanoma.
Among the 3 types, melanoma is the skin cancer type which is most dangerous since it may result in death. The other two types of skin cancers are 100% curable.
Basal cell carcinoma occurs on face and neck. It can be treated easily and cured completely with surgery or radiation. Squamous cell type of cancer is less common and they occur in lips, ears and neck. Melanoma occurs very less when compared with other two types and it can cause death if not detected at early stages.
