I haven't heard anything since having a hysteroscophy due to post menopausal bleeding. I was taking tamoxifen after having a lump removed from my breast.I have since been given an alternative treatment but my oncologist has suggested I go back to gynecology as he saw that my biopsy was inconclusive. He said in a small number of cases the tamoxifen can cause endometrial cancer so it needs checking. Is there a simple blood test which would put my mind at rest. I have asked my GP to chase up my follow up appointment. The biopsy was done in September so I don't get what the hold up is.
