The main manifestation of breast hyperplasia is breast pain, it is because of the breast pain to seek medical treatment, most of the pain is not serious, occasionally walking and clothing rubbing when the pain is obvious. Some of them can find a lot of small hard nodules, like the skin of bitter melon, or find an area hard like a lump, about 20-30 women have a history of breast pain. A few have nipple discharge, most have a small yellowish or colorless discharge. In the breast clinic, the percentage of breast pain visits is even higher, about 70%, and is the most common reason for visits, followed by breast lumps and nipple discharge. Breasts are female reproductive organs and are affected by hormone levels. Like the uterus, the mammary glands have periods of hyperplasia and repair, which are cyclical in nature, and the pain of breast hyperplasia is characterized by aggravation before menstruation and significant relief after menstruation. Nodules or lumps become less noticeable or disappear after menstruation, and most women have experienced this feeling, which lasts for varying lengths of time. Clinicians diagnose breast hyperplasia on the basis of a lack of objective basis, mainly on the basis of the patient’s breast pain, can be detected similar to the bitter melon skin-like hard nodules, aggravated before menstruation, relieved after menstruation. Most of the patients do not need special treatment and can be relieved by themselves. Those with significant pain can take medication under the guidance of a breast specialist to relieve symptoms. Breast enlargement needs to be examined, and the main methods of examination are breast color ultrasound and X-ray photography. Color ultrasound performance in various forms, most of the breast did not see obvious abnormalities, followed by the performance of nodular, clear boundaries, echo uniformity, no obvious blood flow signal, or even manifested as a clear mass, occasionally similar to the performance of breast cancer. The main purpose of ultrasonography is to find out whether there is a lump or not. If there is a lump, it is important to identify whether it is a cyst, fibroadenoma, simple ductal dilatation, abscess, breast cancer, and so on. Color ultrasound images have high resolution and can easily detect lumps, and about 2/3 of the images can clearly characterize the presence or absence of breast cancer. Most mammograms show disorganization of the glandular structure. For breast cysts, fibroadenomas and other benign lesions, color ultrasound sensitivity is higher, X-ray photography can be no lump found. If the ultrasound found a lump, it is difficult to determine the nature of benign or malignant, you can increase the X-ray photography to see if there are characteristics of breast cancer. Clinician consultation, combined with ultrasound and X-ray examination, about 90% of breast cancer can be determined. Ultrasound-guided biopsy can determine the nature of the pathology with an accuracy of about 90%+.
