Great that the scan is clear @Marycipk - and that you are going well with recovery.
Hubby is going thru private chemo just now (at our local private hospital) - He always sees the Onc before starting treatment ($100 of which about $60+ is repaid by medicare - last year we reached the 'threshold' in Oct, so no more fees.) The cost of chemo is totally covered, but for some reason, he has to pay for a couple of the meds that they hand out each time ($6 each.) If we went to our closest town with a public hospital or cancer centre, it would all be free, including the Onc fee .... but that is 1/2hr away & a dangerous road when wet .... We have the same Onc & I go there for my appts for free (no chemo), but we are keeping it simple for hubby's chemo treatment and have it at 'home'.
Definitely ask the Onc about expected fees before you see them next week - and if big $$ are mentioned for chemo, ask why? A different Onc may not 'charge'? Has someone already indicated to you that it WILL be exxy? Usually a written quote is given, too.
Do you have a Breast Care Nurse? They could do the questioning on your behalf & get back to you?
