onco type testing

I don't know what type of cancer you have, but I asked what was the outcome of chemotherapy and radiotherapy treatment, would it shrink the tumour much and improve my chances. The oncologist said It may not shrink the tumour much and there's no guarantees. I felt that the chemotherapy and radiotherapy treatment would have to be of significance to make it worthwhile prior to 9 hours of surgery. Ask questions and do some research. Good luck and kind regards Frank.
