I was recently diagnosed with breast cancer - invasive ductal - size 1.5 cm with clean tissue margins and with negative node involvement. My estrogen and progesterone receptors are both postive and my HER2/NEU is positive (3+). I have an appointment next week with an onocolgist to discuss treatment options. Several people have told me that the recommendation with be radiationa and chemo - is there any one on this message board who has any information as to the standard treatment options? I am confused as to why chemo would be given for such a small tumor with all clean tissues and nodes. Can anyone help?
