I met with a highly recommended oncologist this week who told me unless I treat my ADH with Tamoxifen it will turn into DCIS and then Invasive Cancer. Is this true? From all that I have read and heard, for some people all they have to do is watch the area and follow-up with mammos, ultrasound, etc. My oncologist is also sending me for an MRI w/contrast. He is worried because some of my ADH is not associated with calcifications. Is this more dangerous than ADH associated with calcification? I keep telling myself that I do not have cancer and that things could be a lot worse. However, I worry about the future and future surgeries and biopsies that may be necessary. I appreciate any information you can give.
