Stopping anastrozole

@lifetraveler Thank you so much for your kindness. I really appreciate it. I hope you have a great week.

I have been on Anastrozole for about 2 yrs (half dose) My metastatic B/C to a vertabrae has been all the while in "sleep" mode I am told, thank god! But I have had dental sugery issues that have prvented me from having more than 2 Zomeda infusions and another D surgery in the next mo or so. The onc. said finish all that surgery, BUT my scans did come back w/ osteopenia in some lower torso to /hip area to now osteoperosis there.
I feel ok, but am anxious and not comfortable with this PA's telling me they will now prescribe me Tamoxafin . I know it has failed a lot of B/C patients pre menopausal and has a side effect of causing a secondary gynocolgical cancer (CELL MUTATION) (the % vary of how many patients present with a new cancer) I have a family history of hysterectomies and do not assess that taking this pill expressly for the presence of osteoperosis is ideal for my particular journey that I have been on off & on largely due to bad surgeons in Fl that did not address a some cancer cells she stated she "left behind" & then oncologists ignoring a lump in my arm pit that I was insisting is very questionable & passing it off as "probably just scar tissue", then begging for a biopsy 4 yrs later as it was growing & a new surgeon who said, "I am NOT going to be too "aggressive with the margins around this tumor" . 2 yrs later I happened to feel something hard there...thankfully I moved in the Pand. to NC w/ Duke B/C Ctr by sheer chance in '21. The Anastrozole is in part causing the Osteoperosis. I read here that Anastrozole acumulates to a certain degree in one's system. True? Also how does Tamoxifen process? does it acumulate or not? Postmenopausal experiences w/ B/C & Tamoxifen anyone?
I just feel it's amazing w/ my keeping up my healthy diet etc, that somehow the B/C is in one Vertabrae has not progressed at all and I am taking a better Calcium absorbing pill now (CAL D3, Mag K2 & doing more strength exercises & trying to up my calcium through more calcium rich foods is worth trying and then getting my 3rd Zomeda infusion in 2.5 yrs would be worth trying before a daily Tamaxofin med. Thoughts, experiences?

You do not have to taper, it will slowly leave your system. I took it for 3 mos and did pretty well, just felt old and had anxiety. Then I had vestibular neuritis and was told not to take it for a few days. I then decided to stop taking it, I’m too afraid that it contributed to the severe vertigo attack which debilitated me for a couple of weeks and from which I still have some residual effects. My chance of recurrence is 5-6% without an AI and 2-3% with it.
I had a 8mm DCIS, HR/PR+HER2-, with a small less than 4mm foci of IDC with a Ki67 score of 2. I had a lumpectomy and radiation. I am 71 and taking or not taking anastrozole doesn’t change my life expectancy, only reduces my recurrence rate. I have mild osteopenia and I don’t want to worsen it either. It’s truly a personal decision that you need to look at everything to help you.
If I were younger or had a larger chance of recurrence, I would certainly “bite the bullet” and take it. Hugs and best wishes.
