Skin cancer. Light micrograph of a section through the skin of a patient affected by basal cell carcinoma (BCC). The surface of the body,the upper layers of the skin,are across top. The tumour itself is the large round mass,here present in a solid nodular form. Basal cell carcinoma is one of the most common forms of skin cancer,and is most often caused by over-exposure to sunlight. The cancer starts as a small flat nodule and grows slowly,eventually breaking down at centre to form a shallow ulcer that persistently bleeds. Basal cell carcinomas rarely spread to other parts of the body. Treatment involves the surgical removal of the tumour or radiotherapy | |
