This patient support community is for discussions relating to breast cancer, biopsy, genetics, chemotherapy, hormone therapy, lumps, lumpectomy, lymph node dissection, lymphedema, mammograms, mastectomy, radiation therapy, reconstruction, and self exams.
First of all, the most common causes of lumps and nodules for your age, even with the family history of breast cancer, is still benign conditions such as fibroadenoma or fibrocystic disease. These would usually manifest in accordance with your menstrual cycle and can usually regress upon withdrawal of menses. However, I agree that you show this to your doctor so that you can be worked up properly.
Regards and God bless.
Thanks again!
