Classic signs of cancer are seen on the mammogram. All category 5 abnormalities typically receive biopsy and if the biopsy results are benign, the abnormality usually receives re-biopsy since the first biopsy may not have sampled the correct area. Category 2 indicates a non-cancerous area such as a cyst or fibroadenoma may be present. The exact causes of cysts are not known, but cysts are known to change with hormonal variations, either during normal menstrual cycles or from post-menopausal hormone replacement therapy . Cysts do not become cancer or increase the risk of cancer.
Fibroadenoma is the most common benign, solid growth in the breasts.
Fibroadenoma is round, movable, and firm. Fibroadenoma has no significant risk of becoming cancer and does not put a patient at increased risk of breast cancer.
