I was on Tamoxifen, 10 mg. for 1 1/2 years. I had too many side effects. Mood swings, aches; and developed gallstones. That was my, particular, set of symptoms. I was told that with my diagnosis, I had a very good chance of no recurring cancer, by my Oncology N.P. She even chose to order me a Screening Mammogram for this year, not another Diagnostic mammogram! I asked her to reconsider, and she would not! So I had to go outside my Cancer Center to get a Diagnostic mammogram ordered for this year. They found a suspicious mass that wasn't on my last Diagnostic mammogram. I had a biopsy the next week and it is same as last cancer, but grade 3. I am awaiting the results of a Breast MRI, in order for my surgeon to decide the type of surgery I will need. I have have been called a cancer survivor. I am glad I never bought into that term, and have been vigilant.
