Brain tumours develop from degenerated brain cells and affect the brain directly or indirectly. Additionally, metastases may develop in the brain which also have to be treated. Tumours in the nervous system are a great challenge as there are many different types of tumours which can occur and they vary greatly in terms of their position , growth characteristics, treatment and the prognosis for the patient.
The therapy demands a combination of many specialist medical disciplines and therapy methods. In addition to surgical treatment options, radiotherapy is very important. The use of radiotherapy allows vital structures to remain unaffected. It is often used as the only type of therapy when the tumour is located in an area that cannot be accessed surgically. It is also used for fast growing types of tumour, which respond well to radiotherapy methods.
