Good news!! Finally got Gus' pathology report. Low grade tumor and wide margins! (1.5cm x 1cm x 0.5cm deep). They recommend keeping him on the benadryl and famotidine for at least a month, if not indefinitely. Should be a 90% (or better) cure rate with surgery alone. The continued meds should help him to not develop new (unrelated) tumors. Hip hip hooray!!
