Skin cancer on the neck is most likely to be basal cell carcinoma or squamous cell carcinoma, which accounts for 80% and 20%, respectively, of all skin cancers. Both types usually develop on sun-exposed areas, such as the neck, head, and face.
Nodular melanoma is a type of melanoma skin cancer. It usually occurs on the head and neck and accounts for 15–30% of all melanoma diagnoses. It tends to grow downward into the skin rather than spreading out.
