I have an oncologist who is down right rude and uncaring. But I like the other three doctors on the team; the surgeon, radiologist and internal medicine doctor. I'd like to keep them. This is with the Iowa Clinic. There is only one other oncologist in my area with this clinic. I am 86 and had 15 radiation treatments with invasive ductal carcinoma. I did fine, but not so well with the tamoxifen. I need an oncologist with some empathy and who cares. Instead of suggesting another option he said, "I don't care what you take" in a very angry, dismissive voice. We were on the phone. He did add "as long as you know the side effects and that it could break your back." I ask if the Tamoxifen could break my back. He said yes because I have osteoporosis. So.... he still never answered my question about why he suggested Tamoxifen and not something like letrozole. I truly wanted to know the answer to that, which was the opening question in our phone conversation.
