Concerned about the side effects of anastrozole
I completed all treatments for breast cancer but now I am supposed to take hormone blocker, named anastrozole. im concerned about the side effects. Has anyone here taken it and did anyone have hair loss?
Interested in more discussions like this? Go to the Breast Cancer Support Group.
That article about "Early breast cancer in the older woman" is a good find, @cindylb. Note that it is from 2012, @samy, but it is a great place to start making lists of questions for your oncologist. I did some digging around as well and found these 2017 articles.
- Aromatase inhibitors for early-stage breast cancer https://www.ncbi.nlm.nih.gov/books/NBK447104/
- Aromatase inhibitors in the extended treatment of early-stage breast cancer https://www.ncbi.nlm.nih.gov/books/NBK447116/
- Aromatase inhibitors as upfront therapy for early-stage breast cancer https://www.ncbi.nlm.nih.gov/books/NBK447121/
@monical, you raise some valid concerns. When your doctor prescribed anastrozole for you, did you have time to tell her about your concerns or are they coming up now as you learn more about possible side effects? Maybe it would be a good idea to schedule an appointment to get your concerns addressed before starting.
This is very interesting article - but written in 2013. I wonder if they have any more recent data - I'll ask my oncologist. But I don't see her until July.
samy.....I hear you on this. I felt and feel much the same way. The results are conclusive that the drugs help with recurrence but not for everyone. It's a mixed bag.......and a tough decision. Keep researching and your answer will come. The good news is, I guess, the drugs are always there for us.

THANK you for that article. It’s the closest to answering my question. It would seem that radiation OR radiation+AI drug doesn’t produce a significant difference mortality. Although this is only one person’s opinion, it doesn’t surprise me. I’ll read it several times, to understand as well as I can … and keep searching for more ino. Bottom line is, I guess, I need some serious convincing that this poisonous drug will be worth it for someone my age…so far, I am NOT convinced. The “lump” I had was never felt, by me or doctor, mammogram found it and subsequent tests confirmed. 1.6cm very deep.

I first had Stage 0 LCIS (Lobular). Had the same biopsy and surgery and two years later I had invasive Stage 1 Lobular Cancer. I was unable to tolerate Tamoxifen and have been unable to tolerate the AI's as well (post mastectomy). I felt awful and I had to pass on the drugs. Did I get Stage 1 because I couldn't/didn't take the drugs? I'll never know .....BUT, I did get very regular screenings and continue to do so (even without breasts) and that saved me. It turned into cancer for me but it was caught very early (luckily). If you choose not to use the drugs, be vigilant about mammograms, ultrasounds and MRI's....don't just settle on a mammogram however. My cancer was NEVER A LUMP...it was originally microcalcifications that tipped them off to the LCIS and it was a painful cyst I demanded they ultrasound that showed something suspicious. The MRI showed the invasive cancer. Up to the day of my surgery to remove my breasts, no lump or abnormality showed up on a mammogram. (But this is lobular cancer and it's tricky that way, grows in lines often vs lumps).
If you try the drugs, you may be pleasantly surprised and have no serious side effect! If you feel truly awful (which I did), you can quit taking it and the issues after taking it small time go away very quickly with no lasting ill effects.
Since they didn't actually find more cancer cells in your lumpectomy.........perhaps watchful waiting is a good option for you.

Samy - You got me curious about this..........I'm not sure the link above will work. I'm not very good at links and such but this is an article on the NCBI-NIH (National Institutes of Health) website.
I looked at several articles. They are written in medical language and it takes a while to plow through them but...this one references 'older breast cancer patients' and treatment options, including AI's. There are several studies listed on the difference between Lobular and Ductal and AI effectiveness and 'the older' patient .........I think we're all 'older', ha ha....but it does address some of our concerns.
If you can't get to the article, Google or Websearch, effectiveness of AI's in early stage or Stage 1 cancer. I found lots of studies.
The upshot I got was this...........the AI's work but side effects and compliance by older patients are a strong consideration and Lobular really is different than Ductal and is just now being treated as such.

Hello - I was diagnosed with Atypical Ductal Hyperplasia (posted a follow-up on the other thread, but see it must have gotten lost in cyber land). I had a stereotactic biopsy and then a surgical biopsy. The pathology came back clear for DCIS. In fact, there were no ADH cells present either which meant those cells were removed during the stereotactic procedure and left me shaking my head over the stress and recovery from the surgery.
So now I am 59 and faced with taking Anastrozole to try and prevent cancer. Due to family history and the ADH, I fall into the high risk category with >30% lifetime risk of developing breast cancer. I won’t take Tomoxifen because I have a family history of stroke. I’m left with Anastrozole as an option but I already have degenerative discs, arthritis, (controlled) hypertension and occasional abnormal liver enzymes. I DON’T WANT TO TAKE THIS DRUG. I’m supposed to start taking it tonight but then realized my oncologist never took a baseline blood for the liver enzymes so I will hold off until I speak w/ her (it’s in her clinical notes but a fairly big over sight if you ask me).I have a 30 day supply and try very hard to just look at this as a “trial”, but it is scary. I don’t have cancer but I have to fill my body with a drug that perhaps will prevent (only) an estrogen fed future cancer, but then maybe I’m taking this all for nothing because I could fall in the percentage of people who never develop cancer (my mother didn’t, but my sister, material aunt and cousin did).
I’m angry. My husband is scared that I won’t feel well. I’m scared that if I don’t take the medication I will regret it. I’m scared that if I do take the medication I will regret it. And though I asked a couple of times, my doctor won’t check my estrogen levels either. I am somewhat bothered by the fact that the FDA has approved the use of this drug to treat cancer, but has not done so for the use of a CPA (chemoprevention agent) for high risk women. I know that, with the support of clinical studies, doctors use drugs for off-label purposes, but it bothers me. Anyway, now I know I am rambling...I just feel that it is all a big crap shoot.
Best wishes to all of you that are dealing with so much...there are some days I feel so overwhelmed by it all it takes my breath away.
Thanks Laurie. I appreciate the response.
No, I haven’t gone beyond surgery. No radiation or hormones yet. They just gave me all the appointments, phone numbers to make more appointments to get the ball rolling with this nightmare. Just trying to figure out what to do.
Thank you for the response.
I have pored over forums and websites and cannot find an answer to a really simple question: Is stage 1 survival significantly different with this drug, any AI drug, for someone pushing 70? If there is no significant difference in mortality rates, I don’t want to take it.
If anyone reads or hears about a study or something specific, I’d REALLY appreciate the link.
