How many different types of skin cancer are there?
There are three types of skin cancer: malignant melanoma, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). Malignant melanomas are the most dangerous type of skin cancer and appear as a skin cancer mole; the signs of skin cancer can be identified by the ABCD method:
Asymmetry – The dark, pigmented area appears wonky in appearance.
Border – the edges may be uneven or appear broken.
Colour – the colour may be inconsistent.
Diameter – most melanomas are at least 6 mm across.
Non-melanoma skin cancers include SCC and BCC types which are less dangerous, although both carcinomas can become painful if left untreated for a long time.
