Skin cancers are divided into two main groups, namely: melanoma and non-melanoma skin cancers. To read more about melanomas click here.
Non-melanoma skin cancer is the term given to two main types (in terms of prevalence) of skin cancer: basal cell carcinomas and squamous cell carcinomas. Basal cell carcinoma is more common than squamous cell carcinoma and in some sunny countries up to 50% of Caucasians will develop one in their lifetime.
WHAT IS A CARCINOMA?
A carcinoma is a cancer that develops on an epithelial surface. Many organs have surfaces that are lined with epithelium (lung, colon, stomach, liver, breast etc.) and if a cancer develops from the lining membrane of an organ, it is named according to the organ that it arises from i.e. lung carcinoma; colonic carcinoma; breast carcinoma; basal cell carcinoma.
