Basal cell skin cancers look like a small, slow growing, shiny, pink or red lump. If left, they tend to become crusty, bleed, or develop into an ulcer. They are most frequently found on the face, scalp, ears, hands, shoulders and back. Squamous cell skin cancers are usually pink lumps. They may have hard or scaly skin on the surface and are most often found on the face, neck, lips, ears, hands, shoulders, arms and legs. They can bleed easily and develop into an ulcer.
Melanoma is the most serious type of cancer. The first sign is often the appearance of a new mole or the change in appearance of an existing mole. Melanomas are more likely to have an irregular shape, be more than one colour and be larger than 6mm. They can be found anywhere on the body but the back, legs, arms and face are the most common locations.
