What are symptoms in skin cancer?

Checking your skin for signs of skin cancer
The symptoms of non melanoma skin cancer can usually be seen quite easily. They tend to occur most often on skin that is exposed to the sun. It will help you to spot skin cancers early if you are aware of how your skin normally looks. That way, you will recognise any changes more easily. Remember to get your partner or someone else you trust to check your back or other areas that you can’t easily see. This is very important if you sunbathe a lot or if you regularly work outside without a shirt on.

There is also information about changes to look for with the skin cancer that develops from abnormal moles (melanoma) on the page about symptoms of melanoma.

Where non melanoma skin cancers usually develop
Skin cancers can develop on or near other non cancerous (benign) skin growths. You should show your doctor any area of your skin that is damaged and does not heal up.

The symptoms of non melanoma skin cancer may be similar to symptoms of other skin conditions. It is worth having any symptom checked by your GP. Your doctor won’t think you are bothering them for something trivial. They can decide whether your symptoms need to be investigated further.


How skin cancers can appear
Skin cancers can appear as

A spot or sore that does not heal within 4 weeks
A spot or sore that continues to itch, hurt, scab, crust or bleed for more than 4 weeks
Areas where the skin has broken down or become an ulcer, you can't think of a reason for this change, and it does not heal within 4 weeks
An ulcer is an area that is breaking down and begins to get deeper. This can be called erosion.

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 commonest 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. They can bleed easily and develop into an ulcer. They are most often found on the face, neck, lips, ears, hands, shoulders, arms and legs.



Bowen’s disease
This is a very early form of skin cancer. It usually looks like a red patch that may be itchy. It can appear anywhere on the skin. But it can also develop on the moist membranes of the body. Moist membranes means soft wet skin similar to the skin on the inside of your mouth. Bowen's disease may appear as a white patch in the mouth or a red patch in the genital area.
