The most common head and neck cancer is basal cell cancer of the skin. Fortunately, this is rarely a major problem if treated early. Basal cell cancers appear most often on sun-exposed areas like the forehead, face and ears, although they can occur almost anywhere on the skin. Basal cell cancer often begins as a small, pale patch that enlarges slowly, producing a central "dimple" and eventually an ulcer. Parts of the ulcer may heal, but the major portion remains ulcerated. Some basal cell cancers show colour changes.
Other kinds of cancer, including squamous cell cancer and malignant melanoma, also occur on the skin of the head and neck. Most squamous cell cancers occur on the lower lip and ear. They may look like basal cell cancers and, if caught early and properly treated, usually are not much more dangerous. Malignant melanoma classically produces dense blue-black or black discolourations of the skin. However, any mole that changes size, colour, or begins to bleed may be trouble. A black or blue-black spot on the face or neck, particularly if it changes size or shape, should be seen as soon as possible.
