What does control rate mean?
Control rate is the effectiveness in reducing or preventing the spread of the disease. For example if the control rate is 80% then in 80% of the cases the radiation oncologist is able to reduce or prevent the cancer from spreading to other parts of the body. 80% is the same as saying that they are able to control the disease in 8 out of every 10 patients. This is only an example. You are encouraged to discuss this with your radiation oncologist.
