Sorry you are here. Our gastroeneterologist told me it was cancer before the biopsy was back. He said he knew what he was looking at, and if the biopsy came back negative, he wouldn't believe it. The next step was an EUS which is a scope with an ultrasound that is used to continue staging the disease. They are able to determine the condition of tissue deeper than what they view with a scope. We had to wait about 2 weeks for a slot for the test, and live outside Boston so there is access to a lot of good medical care in the area. They can't really determine treatment till they have fully staged it, and know if it has spread anywhere else.
Is there anyone who does patient advocacy where he gets medical care? He is probably going to need someone to help him seek out available resources for medications like anti-emetics if he has chemo (drug companies have programs to cover the best anti-emetics that are used with aggressive treatment regimens), as well as some kind of coverage for medical care. Although we haven't used them, I know the American Cancer Society has resources for patients, so maybe if you called the local group they could send you in the right direction.
