Rectum/anus

Surgery remains the most important method of treatment for malignant tumours of the rectum. If possible, the tumour is removed completely, , including a sufficient safety margin around the affected area. With localised, already advanced tumours, additional treatment is advised. In principle, radiotherapy can take place before or after surgery. One option is pre-operative radiotherapy in combination with chemotherapy. Post-operative radiotherapy can also be performed if the tumour has already exceeded a certain size and/or lymph nodes are affected by cancerous tissue.

The primary aim of the radiotherapy is to reduce the size of the tumour before surgery, or to prevent recurring localised growth of the tumour after surgery. A carcinoma of the anus is generally not treated surgically, but can be successfully treated with radiotherapy.
