breast fibroadenoma
Introduction
Introduction to breast fibroadenomas Breast fibroadenomas are mixed tumors that occur in fibrous tissue and glandular epithelium in the lobule of the breast and are the most common type of benign breast tumor. Breast fibroadenomas can occur in women of any age after puberty, but are more common in young women between the ages of 18 and 25. The occurrence of this disease is related to the excessive stimulation of estrogen, so it is more common in women with sexual function during the 20-25 years of age. During pregnancy and lactation or premenopausal, the tumor can grow rapidly due to the secretion of estrogen. The most common sites of breast fibroadenomas are more than the upper quadrant, and most (about 75%) are single-shot, and a few are multiple, characterized by painless isolated masses, which are accidentally discovered by accidental narratives; The mass is round or elliptical, with a diameter of 1 to 5 cm. Occasionally, a giant fibroadenoma can be more than 10 cm in diameter. The menstrual cycle has no effect on tumor size, and there is no abnormal nipple discharge. slow. basic knowledge The proportion of illness: 0.24% Susceptible people: young women aged 18 to 25 are more common. Mode of infection: non-infectious Complications: breast cancer
Cause
Cause of breast fibroadenoma
The occurrence of this disease is related to the excessive stimulation of estrogen, so it is more common in women with sexual function during the 20-25 years of age. During pregnancy and lactation or premenopausal, due to the large secretion of estrogen, the tumor can grow rapidly; animal experiments have also confirmed that A large amount of estrogen can induce tumor formation.
