Basal cell carcinoma after radiotherapy. Close up of the site of a basal cell carcinoma (or rodent ulcer) on a patient's cheek (at centre), three months after radiotherapy treatment. X-rays have been directed at the ulcer to destroy the cancerous cells. The treated site appears as a pale, circular patch. The scarred, flaky skin has many small capillaries (telangiectasia), one of the side effects of this treatment. Radiotherapy can cure this particular skin cancer. Although unlikely to spread, a rodent ulcer is locally invasive and will erode underlying tissue, if left alone. M131/204 after 1 month of radiotherapy).
