Hydrea and Tamoxifen

In November 2025 I was dx with DCIS. I had a mastectomy with clear margins and no lymph node involvement. At that time I was also dx with high platelet count. Since my platelets were high I was not put on Tamoxifen although that was recommended as Tamoxifen increase chances of clotting. In June, I started taking Hydrea which has lowers my platelet count somewhat. I will be on Hydrea for life. I am wondering if anyone else has taken both Hydrea and Tamoxifen? I am 76 years old and will continue to have alternating MRI and Mammograms every year. Has anyone else forgone taking Tamoxifen and just relied on yearly exams?
