Basal cell carcinoma
Basal Cell Carcinoma is the most common form of skin cancer and occurs most frequently on sun-exposed regions of the body. BCC makes up about two-thirds of non-melanoma skin cancers.It generally tends to occur in older individuals, although they may occur in young adults and even children. Risk factors for BCC are:
- Chronic sun exposure, especially in people with fair skin, light hair, and blue, green, or grey eyes
- Exposure to radiation
- Arsenic intoxication
BCC commonly develops on the head, neck and upper body. It may appear as a pearly lump or a scaly or dry area that is pale or pink in colour. BCC may bleed and become inflamed, and dead tissue may slough off (ulcerate). Some BCCs heal then break down again.
BCCs tend to grow slowly and don't usually spread to other parts of the body. However, if BCC is left untreated or grows larger than 5 cm, it may grow deeper into the skin and damage nearby tissue. This may make treatment more difficult and increase the chance of the BCC returning.
