I am a 56 F that has gone through Breast cancer, IDC,ER positive, found early in 1 lymp. Had lumpectomy, chemo, radiation that ended in July 2013. Decided not to take the breast pill for 5 yrs, concentrating on nutrition , staying away from foods that are processed, filtered water & using turmeric vit k, about the first month of chemo , started having this really bad back pain that would come & go. I was a former smoker, quit last July. I recently started having that same middle of back pain, had chest X-ray, MRI, Pet/CT, last week had biopsy of left lung(cancer was in Rt breast) the results came back negative, but my onco just does not believe I am cancer free, because part of lung is collapsed. The cancer markers have not changed, blood work ok, am going to see a neurologist next week, now he wants me to go to a Pulmonary have another test done. I just don t know what to do, he is one of the best onco s, just. Feels something not right? So I am looking at Lung Cancer... Just confused as to what to do????
