Non-melanoma skin cancers usually develop in the outermost layer of skin (epidermis) and are often named after the type of skin cell from which they develop. Non melanoma skin cancer includes 2 main types: basal cell skin cancer and squamous cell skin cancer.About 80% of these new skin cancer cases are basal cell carcinoma (BCC), 16% will be squamous cell carcinoma, and 4% will be melanoma. On a preventive health note, it has been estimated that regular application of sunscreen with a sun protection factor (SPF) of 15 or greater for the first 18 years of life would reduce the lifetime incidence of non-melanoma skin cancers by 78%.
Surgery is the main treatment for non-melanoma skin cancer. This involves removing the cancerous tumour and some of the surrounding skin.Other treatments for non-melanoma skin cancer include cryotherapy, creams, radiotherapy, chemotherapy and a treatment known as photodynamic therapy (PDT). Non-melanoma skin cancer is mainly caused by overexposure to ultraviolet (UV) light. UV light comes from the sun, as well as artificial sunbeds and sunlamps. In addition to UV light overexposure, there are certain things that can increase your chances of developing non-melanoma skin cancer, such as: a family history of the condition, pale skin that burns easily, a large number of moles or freckles
