Judging by your post you must be younger with 3 kids. In that case you should inquire to your doctor and go on line about clinical trials. Your husband may be a candidate for something promising. In my wife's case she was not eligible for any clinical trials because of her age. Hopefully they were able to get most of the cancer out which will increase his chances. Our prayers are with you and your family. Please keep us posted on the progress.
