What is breast fibroma?

After a girl turns 10, her breasts begin to develop and grow slowly. However, during this process, if the breasts are underdeveloped, breast fibroma will grow. Breast fibroma is a type of tissue fiber that grows in the subcutaneous tissue. It mostly occurs in adolescents. This type of breast fibroma is divided into benign and malignant. You must go to the hospital for treatment as soon as possible. If it is malignant, it can be life-threatening. Here I will explain to you what breast fibroma is. .

Breast fibroadenoma is a benign tumor composed of a mixture of glandular epithelium and fibrous tissue. It is common in young women and is related to an imbalance in sex hormone levels in the patient's body. This disease is also known as adenofibroma and adenoma, which is due to the different degrees of fibrous components and glandular epithelial hyperplasia that make up the tumor. When the tumor is mainly composed of glandular epithelial hyperplasia with fewer fibrous components, it is called fibroadenoma; if fibrous tissue accounts for the majority of the tumor and the glandular duct components are relatively small, it is called adenofibroma; when the tumor tissue is composed of a large number of glandular duct components, it is called adenoma.

The above three classifications only differ in pathological morphology. Their clinical manifestations, treatments and prognoses are no different, so they are collectively called fibroadenomas. Breast fibroadenomas are common in the upper outer quadrant of the breast. They are round or oval in shape, clinically 1 to 3 cm in size, and grow slowly, but may grow rapidly during pregnancy or lactation. Fibroadenomas that occur in a very small number during adolescence can rapidly increase in size within a short period of time, with a diameter of up to 8 to 10 cm. These are called giant fibroadenomas and are still benign tumors. It is extremely rare for fibroadenoma to transform into fibrosarcoma or breast cancer, less than 1%.

It is usually a single attack, but in 15%-20% of cases it can be multiple. It can occur unilaterally or bilaterally. They are generally round or oval, and large ones may be lobed. In the early stage, it is the size of a soybean and grows relatively slowly. It may remain unchanged for several years. Because there is no obvious discomfort, it rarely attracts the attention of patients. The lump grows gradually without being noticed, and because of shyness, the patient is unwilling to see a doctor for examination, and only goes to the hospital for diagnosis and treatment when the lump grows larger, delaying the treatment.
