Skin Cancer Lesions and Sites

There are three major types of skin cancer – Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC) and Melanoma. Skin cancers are caused by over exposure to UV radiation and can appear anywhere on the body.

Solar keratosis also known as actinic keratosis are scaly pre-cancerous spots on the skin caused by high exposure to UV radiation.

BCC is the most common type of skin cancer, usually occurs on sun exposed areas of your body, such as the head and neck. Appears as pearly, pink lumps or flat skin cancer lesions that vary from pink to dark brown. BCCs do keep growing, however it is extremely rare for these tumours to spread through your body. As they grow they ulcerate or appear like a sore that fails to completely heal.

SCC often occurs on sun exposed areas of your body, such as face, ears, scalp and limbs. Appear as firm red nodules or flat lesions with a scaly, crusted surface. These tumours do have some risk of spreading to other parts of your body.

Melanoma can develop anywhere on the body, not just sun exposed areas, can arise in otherwise normal skin or in existing moles. Melanoma is the most dangerous type of skin cancer. Often melanoma appears as changing brown or black spots. Melanoma can grow very quickly if left untreated and can spread to other parts of your body. If you think you have a melanoma you should request to be seen urgently. We are able to offer priority appointments for urgent concerns.
