MODEL RELEASED. Chin removed due to tumour. Image 2 of 2. Facial profile of a patient whose chin has been removed due to a jaw tumour. The tumour was a myxoma. This is a benign tumour of connective tissue. A benign tumour is not cancerous, but it may still need to be removed if it turns cancerous or if it grows so large that it interferes with normal functions. Photographed in Africa. For the tumour before removal, see image M131/521.
