Concerned about the side effects of anastrozole

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.

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.

OMG!! this is ME! Going through d same exact thing… don't know which way to go.… I'm like I don't want to take this med (Tamoxifen) it can cause uterus cancer and stroke, blood clot just a whole lots of stuff!
