My ex wife had a complete hysterectomy 6 months to the day after the birth of our 2nd child as a result of dealing w endometriosis for several years. Hormone replacement therapy never agreed with her system.. Too much .. Too little... @ 6 years ago she was diagnosed with Non Hodgins Lymphoma. I have wondered if the HRT had any cause in this unfortunate diagnosis?
A couple of years prior to my hysterectomy, I underwent two surgeries to remove pre-cancerous tumors in my breast.
After my hysterectomy, my gynecologist refused to put me on HRT because of my history and my family history with cancer. Ever since my hysterectomy, my mammograms have been clear. I’m grateful to my doctor for his decision.
OTOH, my sister also told underwent a hysterectomy for severe endometriosis. She was put on HRT and, a few years later, developed Breast Cancer. Fortunately, it was caught in the early stages and she didn’t require chemo or radiation.
I wouldn’t be surprised if your ex’s Lymphoma was caused by the HRT.
