The difference between a breast fibroadenoma and a breast nodule is that a breast fibroadenoma is a disease and a breast nodule is a symptom. 1. Breast fibroadenoma: Breast fibroadenoma may be caused by an abnormally high sensitivity of fibroblasts in the lobules of the breast to estrogen. It manifests as a removable breast lump and usually has no other significant self-conscious symptoms. The main treatment for breast fibroadenoma is surgery. Surgical treatments mainly include traditional incision, lumpectomy and vacuum-assisted minimally invasive rotational excision. 2. Breast nodule: Breast nodule is a clinical symptom that does not specifically refer to a certain disease. Breast hyperplasia, mastitis, breast trauma, breast cancer and breast cysts, the clinical symptom can be manifested as breast nodule. If the above symptoms persist without relief, timely medical treatment is needed.
