Skin cancer isĀ  a malignant lesion of the skin that may or may not metastasize. Overexposure to the sun is a primary cause. Diagnosis is confirmed by a skin biopsy that is positive for cancer cells.

Types of skin cancer

  1. Basal cell: Basal cell cancer arises from the basal cells contained in the epidermis; metastasis is rare but underlying tissue destruction can progress to organ tissue.
  2. Squamous cell: Squamous cell cancer is a tumor of the epidermal keratinocytes and can infiltrate surrounding structures and metastasize to lymph nodes.
  3. Melanoma: Melanoma may occur any place on the body, especially where birthmarks or new moles are apparent; it is highly metastatic to the brain, lungs, bone, and liver, with survival depending on early diagnosis and treatment.
