Skin Cancer Types


Melanoma is the most dangerous form of skin cancer. If not caught and treated early, it can spread to other parts of the body and be fatal. It may appear in a mole or a dark spot or on clear skin. Usually it appears on parts of the body that are exposed to the sun, however, it may appear in arears where there is no or very little sun exposure.

Nodular melanoma is an especially dangerous form of melanoma. It appears as a new small round lump. It may be pink, red, black or brown in colour. It grows very quickly and can become life threatening in six to eight weeks.

Melanoma often has no symptoms, so it is very important to have regular checks. If caught early the cure rate is very high, if caught late the cure rate drops significantly.

Squamous Cell Carcinoma

Squamous cell carcinoma is the second most common skin cancer and can grow quickly within a few weeks or months. It accounts for about 30% of non-melanoma skin cancers. It is not as dangerous as melanoma but can spread to other parts of the body if not treated. It usually appears where the skin is exposed to the sun – head, ears, lips, neck, arms and legs. SCC on lips and ears are the most dangerous in terms of spreading. It usually appears as a thick red scaly spot that doesn’t heal.

Basal Cell Carcinoma

ost common skin cancer and accounts for about 70% of non-melanoma skin cancers. it is also the least dangerous. It usually appears as a lump or scaly area, originating in the top layer of the skin. It grows slowly. It could be red, pale or pearly coloured and is usually found on face, nose, ears, neck, shoulders and back, however it could appear anywhere on the body. Sometimes it ulcerates or presents as a sore that doesn’t heal properly. Usually it can be easily treatable.

If you find anything unusual or suspicious on your skin it is always best to have it examined by a qualified medical practitioner.
