It is best to discuss your individual treatment in detail with your doctor. Make a list of questions you may want to ask and don't be afraid to ask your doctor to repeat any answers or explanations you don't understand. You may like to take a close friend or relative to the appointment with you. If you are feeling upset, they might be able to remember details of the consultation which you might have forgotten. You may want them to ask some of the questions you yourself might be hesitant of putting to the doctor.
Some people are afraid of the hospital itself.
You may find the doctors can't answer your questions fully, or that their answers sound vague. It is often impossible to say for certain that they have completely removed the tumour. Doctors know from past experience approximately how many people will benefit from a certain treatment, but it is impossible to predict the future for a particular person. Many people find this uncertainty hard to live with - not knowing whether or not you are cured can be disturbing. Uncertainty about the future can cause a lot of tension, but fears are often worse than the reality.
