Symptoms of Cancer of the skin

Rodent ulcer (basal cell carcinoma) is one of the commonest of all cancers and one of the least dangerous. It affects the skin, mainly in areas exposed to the sun, and especially on the nose and around the eyes.

It is a slowly growing, raised-edged swelling with a dimple in the centre. Small blood vessels are often visible just below the surface. It hardly ever spreads to other parts of the body, although it can do so if neglected. It can then cause a lot of tissue damage, especially by burrowing deep into the tissues (hence the name rodent ulcer).

Squamous cell carcinoma is a skin cancer also related to sunlight exposure. It starts as a small, firm, painless lump occurring most often on the lip, ear or back of the hand. It enlarges fairly rapidly and then will often break down in the centre to form a crater. This is called ulceration. It can spread to the lymph nodes and from there to various parts of the body. Be very suspicious of anything like this on your lip.
