Hello Gina, So sorry you have to be here.
I totally agree with Christine. Your Husband would be best treated at a CCC with a team approach. This is complicated and involved surgery and treatment. Plus , he has existing medical problems. May I ask what age he is? You should also discuss with the Team Quality of Life issues.
The biopsy results should be all you need to get a definitive diagnosis.
Best of luck,
Tammy
