I too consulted with multiple oncologists and received similar but not identical ideas on the treatment side. I was confused about what route to take, but I was quickly brought to my senses by both the specialist who performed my endoscopy and a daughter-in-law international cancer research coordinator who put it simply: we fortunately live near a nationally ranked Comprehensive Cancer Research and Treatment Center. We should take the preliminary diagnosis measures performed at a nearby general hospital and then get discharged with a referral to the CCRC. It's a beyond-impressive facility with top shelf professional and staff expertise. The 57 nationally top-ranked treatment centers are listed at Wikipedia:
