What is Radiation Therapy?

Radiation therapy is one of the main methods of treating cancer. It uses machines called linear accelerators to deliver precise and focused high energy x-rays to damage or kill cancer cells. It is a powerful and well proven tool used in the battle against cancer. It has revolutionized the management of many tumors and improved the outcome of persons suffering malignancy over the past few decades and saved countless from hardship and mortality.


What are the Complications That May Arise from Radiation Therapy?

As in all therapies - not all outcomes are equally favorable. In a small percentage of those who receive radiotherapy, the tissue response is accentuated and damage to normal tissue occurs. The unpleasant effects usually settle post irradiation, however not in all cases. 

Problems can manifest in many ways, however the common underlying feature is a loss of the normal ability to perform “housekeeping chores” of tissue repair and maintenance. 

The unwanted biological effects of radiation exposure (Complications) can be divided into 2 groups:
1. If sustained following treatment the problem is called persistent radiation effects. 
2. If the initial inflammation settles and then after 3 months or more, tissue deterioration and loss of function develops, this has been termed radiation late effects.






What Options are Available for Those Suffering from Radiation Therapy Complications?

That clinic has helped  > 1000  patients to date. A range of therapeutic options has been explored to meet the needs of this population:
