New member: stopping AI is a greater risk of reoccurrence?
I am 76 and was diagnosed with breast cancer on March 31st. My cancer was found in a backwards way. I had a clear mammogram in December 2024 and breast reduction surgery in February 2025. A 3 cm tumour was found in the 1kg of tissue that was removed from my right breast. I am so thankful I had the reduction surgery.
In May I had sentinel node surgery and 6 nodes were removed and they were clear. Tumour is Estrogen+ progesterone +, HER2-; grade 2; onco score 9; no DCIS. I just finished 5 days of radiation.
Radiation oncologist said the radiation would reduce my risk of reoccurrence from 8% to 2.4%. (I’m pretty sure that is local reoccurrence.) Medical oncologist said taking AI would reduce my 10 year risk of dying from this BC from 8% to 5%.
I have an appointment with my oncologist next week to tell her if I agree to take Anastrozole. I am still undecided considering my age. It’s a personal decision but I do appreciate what members have written about their experience.
I have read anecdotally that starting hormone blockers and then stopping can increase your risk of reoccurrence. Does anyone know if there has been any research done in this area?
Thank you for sharing your stories. I am so pleased that I found this group a few days ago.

I am 75. Not taking AIs would increase the 9 year recurrence rate from 3% to 6%. The oncologist said look at it this way. Do you want a 97% on your test or would you be happy with a 94%. I had IDC Stage 1 Grade 1. Oncotype score was a 1. I have no genetic mutations. My sentinel node biopsy was clear. I did opt for 15 days of radiation because I am hesitant to take AIs. I already have fibromyalgia, chronic fatigue syndrome, muscle and joint pains from neck and back surgery, and have had migraines since I was 12. I had another bone density scan and I have osteopenia (same diagnosis in 2009). I would prefer 9 more decent years of life and not 9 years of misery. I’m still working! One more visit with the oncologist for my final decision in two weeks.
My surgery was breast reduction in February. The tumour was found in the pathology after a clear mammogram in December. I had an MRI, sentinel node biopsy and 5 days of radiation. I’m done now and feel good about my decision.
Hi! eleanorrigby:
My heart aches and my prayer goes out for you upon reading your post... Life truly threw curve balls at us from time to time, and sometimes it seemed to be even cruel, isn't it?
I admire your perseverance of dealing with various cancers bravely over the years; indeed, I sympathize with you for trying to avoid surgery. However, I am no medical expert and I had already gone through my surgery to get rid of my IDC tumor on 12/26/2023, for as far as I understand surgery is the most effective way to get rid of cancerous cells from our body. I pray that when you finally meet the expert in a week, you'll get the best advice to make your informed decision with a peace of mind. In the meantime, if you haven't done genetic testing for cancer risk yet, please consider discussing it with your physician. I feel this is beneficial for our blood relatives, because early detection is the key to successfully treat any kinds of cancers. I am also encouraged by your taking Anastrozole for 2 years, and it apparently shrinks your cancerous cells significantly that the breast cancer went into hiding:) Wow! If I understand you correctly, your last MRI, US, Mammo done in June showed no sign of any cancerous cells, right? What great news to share with us! Thank you!
Best wishes for all on the journey ahead!
That's very sweet of you! Yes, it appears that the Anastrozole shrunk the cancers into oblivion but I have several doctors that say "it's unlikely to get rid of the cancer." And I have several doctors who have said, "Well! Great news! It is possible that they won't come back!" So that's why I'm confused all the time since I am always getting different answers...surgeons, oncologists, etc. So I am really laying my hopes on the wonderful doc I am going to see in about 10 days. I just want her to clarify and I want percentages, etc.
I did do the genetic thing already. MD Anderson does them for people like me, if not every breast cancer patient. Can't speak to whether or not everyone gets the genetic testing. Mine was negative on all counts...there is no genetic link, nothing for my relatives to be concerned about in that regard. You are correct that my latest tests in June showed no sign...we simply see no cancer...but some doctors have stated that AI won't kill the cancer all together, but some say it can. So who knows?
Thanks so much for your kind comments! I'm glad you had your surgery and it turned out well! Thanks for your support.
I don’t think I am. I believe I read the trying different manufactures on Facebook. And I heard the lower dose thing on a cancer podcast talking about a study / i did check it out myself but that was a couple months ago.
I understand exactly! One has to decide what will give them decent years of life...whatever we have left! That's what I am trying to decide. I think I have most of the AI side effects, which of course I weigh as opposed to surgery. No clue what I will end up doing, but I sure would like to hear a 94% or 97% change of perhaps another 5 years of life with just the AI and no surgery, and I would be fine with that!
May I ask how you knew it had stopped working?
It waqsn't mine...it was my friend's who stopped working and I'm not sure if it was her lab tests or what. But I'll ask her and let you know.
@phonso So I talked to my friend, and she said when she went for a checkup (MDAnderson), some key enzymes they watch in her blood started spiking which "indicated the cancer was active again." They changed her from Tamoxifen to Letrozole and her numbers went back down.
