I am sorry this outcome has not gone as planned or expected. It always amazes me how our lives come to a screeching halt when we are faced with the treatment and cure for cancers.
At this point you can only wait to find out the next step or steps and then head down that road. No doubt your husband feels like he can take no more disappointments. Courage. I am always watching for your posts as I am sure others are as well.
Will treatment begin in the next few days or will he need some time to heal from the surgery?
