While hoping that your biopsy comes out negative, if it is positive, then consider getting a second opinion on treatment from a CCC. Based on your description of level of care so far, it would be time well spent. The caseload statistics are all very well and good but they don't show how many of the diagnosed cases were treated successfully. I stuck with an RO whose administrative staff and facility scheduling were much less than optimal based on his amazing track record of cures for Stage IV.
Even thought there is no Stage V, there is still HOPE for a complete remission even if your diagnosis was as late as mine ("guesstimate" that tumor had been growing for six years before spreading to lymph nodes in seventh year)
Good luck
