Breast fibroadenoma is a kind of benign breast tumor, which is clinically common in young women aged 18-35, generally single, about 20% – 30% are multiple, multiple can be divided into two cases: 1, two or more tumors can appear in both breasts or unilateral breast at the same time, 2, single tumor reappears after surgical removal. The clinical manifestation of this disease is a lump in the breast with hard texture, mostly with clear border and good mobility, usually without obvious pain, but a few patients feel swelling and stinging discomfort or mild pressure pain before menstruation, with the increasing incidence of breast diseases, this disease is also on the rise. Most of the tumors grow slowly, but during pregnancy or lactation, the growth is more pronounced than before. Typical fibroadenoma is not difficult to diagnose through symptoms and signs, and the following auxiliary examinations can be used; 1. Molybdenum palladium X-ray; it shows a round or oval-shaped mass with density slightly higher than surrounding tissues and uniformity, with smooth and sharp tumor border and little calcification. 2. The internal echogenic distribution is uniform, with lateral acoustic shadow, and a few with calcification may appear acoustic shadow. 3.Infrared scan; most of the tumors are basically consistent with the surrounding normal breast tissue transmission, and some of them show gray-white shadows with relatively sharp edges and uniform density, without abnormal changes of surrounding blood vessels. It should be reminded that the breast tissue of young women is dense and absorbs more radiation accordingly. Since mammography is somewhat radioactive, for those who can be clearly diagnosed through medical history, physical examination and ultrasound, the use of radiography should be avoided as much as possible, which itself can reduce and minimize the occurrence of breast diseases. For unmarried women with a clear diagnosis of a small tumor, they can also be observed or given Chinese medicine to regulate the disease. Prevention: We should pay attention to breast disease screening and self-examination, maintain a relaxed mood, not to use hormone-containing drugs, food and health care products (including the external use of beauty and skin care products containing high estrogen, avoid or reduce X-rays and other ionizing radiation, combine work and rest, strengthen exercise, reduce excessive intake of animal fat, and control body weight. For those who have multiple fibroadenomas, they should actively receive Chinese medicine for endocrine regulation, and give evidence-based treatment to reduce the recurrence of tumors and recurrence.
