I have been on treatment for a year now, including palbociclib, fulvestrant and denosumab.  I only have one definite tumour on my iliac crest, the other one is not conclusive because of the operations I have had in that area in the past.  My question is, it says in some of the books that I can request a single radiotherapy dose on this tumour, because, as it is in the bone you cannot measure if it is shrinking and, ff it is, how much?  My oncologist has turned me down with no reason.  I am thinking of paying privately.
