I had Stage 2 HER2 Positive breast cancer in 2013. Total axilla node dissection as sentinel node was positive even though my tumor was only 1cm. I had a lumpectomy and was placed on Tamoxifen after surgery. I am now six years out and still on Tamoxifen with no noticeable side effects. My plan was to stay on the Tamoxifen for 10 years. I am now 68 years old and about to head toMayo in Rochester for my post 6 year appt. Every year we discuss coming off the Tamoxifen and so far I have decided to stay on it. I may be lucky not to have any side effects. So far my bone scans have shown mild osteopenia.
