Skin cancers are cancers that arise from the skin. they're thanks to the event of abnormal cells that have the power to invade or spread to other parts of the body. There are three main sorts of carcinoma s: basal-cell skin cancer (BCC), squamous-cell carcinoma (SCC) and melanoma. the primary two, alongside variety of less common skin cancers, are referred to as nonmelanoma carcinoma (NMSC). Basal-cell cancer grows slowly and may damage the tissue around it but is unlikely to spread to distant areas or end in death. It often appears as an easy raised area of skin which will be shiny with small blood vessels running over it or may present as a raised area with an ulcer.Squamous-cell carcinoma is more likely to spread. it always presents as a tough lump with a scaly top but can also form an ulcer. Melanomas are the foremost aggressive. Signs include a mole that has changed in size, shape, color, has irregular edges, has quite one color, is itchy or bleeds.
