Review on Fibroadenoma
Abstract
Fibroadenoma, is a painless benign breast tumors characterized by amixture of stromal and epithelial tissue. Breasts are made of lobules and ducts tubes that carry the milk to the nipple. They are mainly formed by glandular, fibrous and fatty tissue. Fibroadenoma develop from the lobules. The glandular tissue and duct grow over the lobule to form a solid lump. It occurs most commonly in young age group of women between the ages of 14 to 35 years but can be developed at any age. Fibroadenomas shrink after menopause, and so it is less common in post-menopausal women. Fibroadenomas are also referred to be a breast mouse due to their high mobility. Fibroadenomas are a marble-like mass comprising both epithelial and stromal tissues located under the skin of the breast. These are firm, rubbery masses with regular borders and are often variable in size. Fibroadenoma are of four types; complex, Juvenile, Giant fibroadenoma and phyllodes tumor. Complex fibroadenoma has rapidly growing hyperplastic cells; the pathologist can establish diagnosis after carefully reviewing the biopsy of breast tissue. Juvenile fibroadenoma is commonly found in patient’s age 10 to 18 years. These fibroadenomas has a faster growing rate and eventually shrink or disappear. Giant fibroadenoma are non-cancerous lesions that are slightly larger than other types. They commonly need excision because they compress or replace normal breast tissue.
