I am one of the lucky ones whose BC was very small (7mm)invasive ductal ER+ tumor discovered at routine mammogram 3 years ago. Tumor & margins removed plus 10 lymph nodes (all negative)followed by radiotherapy. I was on Tamoxifen initially but couldn't tolerate it (extreme vaginal itching and discharge)so was switched to Arimidex about a year ago. I am now starting to experience discomfort on this, has any one else found this? I have a check-up this week, supposed to be 6 monthly but is 9 months since last one, I'm tempted to ask to come off Arimidex. Am post-menopausal, sister died of BC at age 45 and maternal aunt, also, so may be genetic tendency. What does the surgeon think? I live in the UK.
