I was not misdiagnosed by a radiologist but was told by my oncologist in February 2018 during a routine exam that I had a "cyst" in my left breast. When I asked my doctor several times if she was sure, she said yes, that she thought it would be gone by the time I had the mammogram she was going to order for "due diligence". I suspected that she was being less than honest; as it turns out, I had a second breast cancer. I dropped her immediately. To accept that your oncologist would intentionally lie to you after knowing you for several years and seeming to take such a sincere and personal interest was devastating. But--I contacted her informed her that I was requesting another oncologist and moved on.
