Breast fibroadenoma is a benign tumor of fibrous tissue and glandular epithelium that occurs in the lobules of the breast. It is the most common benign breast tumor in clinic, accounting for about 3/4 of the benign breast tumors. it can occur at any age after puberty, but it is more common in young women aged 18-25 years old, the vast majority of them are unilateral, single painless lumps, which are mostly found unintentionally; they are small at the beginning, but they grow fast, and when they reach 3cm in length, the growth is slow or stops growing; they are round or ovoid, with clear boundaries and smooth surfaces, moderate hardness, mostly without pressure pain, and can be pushed freely. The tumor is round or ovoid, with clear boundary, smooth surface, moderate hardness, mostly without pressure pain, and can be pushed freely. The tumor grows slowly and has no other symptoms. Breast fibroadenoma has little relationship with breast cancer, and the rate of malignant transformation is also very low. However, during pregnancy, fibroadenomas can grow suddenly and become sarcomatous. women over 40 years old, especially those who develop fibroadenomas during menopause and postmenopause, have a higher risk of malignant transformation. The effect of medications on breast fibroadenomas appears to be minimal, and surgery is the only effective treatment for this benign tumor. Young patients with breast fibroadenomas must be highly vigilant and undergo checkups in the hospital every six months to prevent the condition from worsening. Multiple breast fibroadenomas are defined as those with more than 2 fibroadenomas in the breast and occur in about 15% of cases. Because multiple breast fibroadenomas can be close to each other and merge with each other, or scattered in one side or both sides of multiple parts, so it is difficult to remove all of them surgically. Therefore, for those multiple adenomas which are not too big in size, the clinic can be treated with traditional Chinese medicine; for those adenomas which are bigger in size, more than 2cm, they can be considered to be excised, and those with smaller adenomas can continue to be observed.
