A basal cell carcinoma is a type of skin cancer. It is a relatively harmless or benign type of skin cancer in that it will not spread to any other sites within the body. Treatment, however, is essential because these tumours can extend or grow into surrounding structures and damage them. If you have been told that you have a basal cell carcinoma arrangements will be made for this to be treated, either by a topical cream, cryotherapy (liquid nitrogen) surgery or radiotherapy.
Basal cell carcinomas are caused by excessive sun exposure (from sunbathing, sunbed use, outdoor work or recreational activities) and are therefore more common in older people. Fair-skinned, blue-eyed, red or blonde haired individuals, who burn easily in the sun but tan poorly, are at particular risk.
If you have had one tumour you have a greater risk of getting a second. The risk can be minimised by protecting your skin with clothing, wear a hat that protects your face, neck and ears, and a pair of UV protective sunglasses. Sunscreens may also help on sites that cannot be covered by clothing. If a sunscreen is used a total block (high sun protection factor and 4 star UVA rating) is preferred. Sunscreens should not be used as an alternative to clothing and shade, rather they offer additional protection. No sunscreen will provide 100% protection.
