OMG, of course you're freaking out. Those are some hard words to swallow. I had an Avastin/CPT-11 treatment two weeks after my second surgery.
they determined the wound (about 30 stitches long) had healed sufficiently. I had no issus.
I agree with the others, move the appt up and ask the oncologist to schedule the infusion with the infusion center so there's no delay. They can always cancel it if need be.
My heart bleeds for all of you. I know she's had a particularly difficult journey.
