I am a six year breast cancer survivor. I am 58 yr. old and assuming that I am through menopause. Last night I felt a lump and/or thickening under my left arm (original side of breast cancer). I have had a double mastectomy and adjuvant chemo after the surgery. The type of cancer was ductal and it had spread within the breast, but not into the lymph nodes. Tumor was 2.5 cm. Since the diagnosis, I tend to be anxious about every lump or bump. The lump that is now under my arm feels very much like the fibrocystic lumps that I used to have in my breast. Considering that the breast and all the tissue has been removed, as well as 14 lymph nodes, with the original surgery, should I be anxious about this? My yearly appointment with my oncologist is not until January.
