Skin cancer is an uncontrolled growth of abnormal skin cells. Without treatment, most skin cancers will continue to grow, invading and damaging tissue in the local area. Some skin cancers (especially melanoma) spread to other parts of the body, causing serious illness and death.
Melanoma is one of the most serious skin cancers. If untreated, it can spread uncontrolled through the body causing serious illness or death.
Melanoma in situ
Melanoma in situ is the earliest form of melanoma, affecting only upper layers of the skin. Long term survival approaches 100%.
Basal cell carcinoma
Basal cell carcinoma (BCC) is the most common, and one of the least serious, forms of skin cancer. It tends to grow slowly and rarely spreads to other organs.
Squamous cell carcinoma
SCC is a common skin cancer, especially in older people. It causes a crusty or scaly lump or patch. It's usually easily treated, but sometimes spreads.
Bowen's disease is a very common mild form of skin cancer, affecting only upper layers of the skin. It tends to grow slowly progression is unusual.
Conditions which develop into or predispose to skin cancer
Certain types of sun damage have a risk of developing into skin cancer.
Benign (non-cancer) lesions
Most spots or lumps on the skin are normal and harmless growths. They appear due to factors such as ageing, heredity, infection or previous injuries to the skin. The lesions rarely require treatment, but cosmetic treatment is often successful.
