Hi Sara--reading everyone's experience w/ Anastrozole. I am wondering cuz I did not see, that you wrote what type of breast cancer you have and are you having a double or single mastectomy, or??
I've been dealing off and on w/ Lobular BC tumors (double mast , 2012,,, then felt a tumor in arm pits 2019, &2022... never had chemo , but did have radiation in '19 & again in '22.
11/30/23 they found a sm lesion on Vertebrae (all BC on left side )- Metastatic Lobular BC to Bone 2cm) Never took Tamoxifen , but NOW have been a mo. in w/ Anastrozole. I was sitting on a fence over the Holidays about taking it...and I have not had the side affects (so far) but had a CT scan today and it was showing so far good, no progression in the last 3.5 mos. THE questionable thing my Oncology PA said was with Metastatic BC the Anastrozole works on avg. 6-12mos. then a different drug is tried....to combat what ever the deterioration of patient's BC... She said "Oh there are some patients w/ metastatic take it for for years and are alive 10 yrs at this point.".... I wonder what happens to a typical Metastic BC to bone patient after 6-12 mos on Anastrozole....

My breast cancer label - I really confirmed it this afternoon. In the left breast it is mammary duct tumor. (After 3 months on Anastrozole it shrank so much my surgeon was shocked.) Then, my right breast is IDC - Invasive Ductal Cancer. That has also shrunk, but not as much as the left breast. On Feb 16 I stopped Anastrozole. On cruise control right now. I am interested in seeing if the Anastrozole keeps on working. Why not? The side effects sure stuck around. Although much better now. My next exam is May 14, my lumpectomy will be May 24. We are very interested to see what the test results will be on May 14. I'll have been off Anastrozole since Feb 16. I will sign off . . . Your Anastrozole Beta Site!!
