In order to protect breast health and keep away from breast cancer, modern women are aware of the importance of breast examination, but most of them may not have scientific understanding of breast examination, I learned that the health examination of breast mainly includes physical examination and auxiliary equipment examination, and advanced examination equipment can often detect some breast cancer without any symptoms, therefore, doctors suggest that those who do not find any problem in physical examination Therefore, doctors suggest that if no problems are found in the physical examination, you should choose the appropriate auxiliary equipment to eliminate hidden dangers. Infrared breast examination: Infrared examination is one of the most commonly used breast examination instruments in small and medium-sized hospitals for its non-invasive and low cost, but due to the limitation of its imaging principle, the detection rate and reliability of breast lesions are much lower than those of ultrasound and mammography. Mammography: The World Health Organization and American Cancer Society recommend that women over 50 years old should have mammography once a year, women between 40 and 49 years old once every 1-2 years, and women between 35 and 40 years old should have mammography once as basic information to be kept for future comparison. Shenzhen Maternal and Child Health Hospital has introduced one of the most advanced (only one in Shenzhen) all-digital mammography machines in the world, which only receives the same amount of radiation as watching half an hour of TV, but can display images several times clearer than ordinary mammography, helping to clarify the location of the tumor, the extent of tumor infiltration, the presence of multiple cancer foci and the situation of the opposite breast, and can also perform localized biopsy for the tiny lesions found under the mammography. For small lesions found under mammography, localized biopsy can be performed, avoiding open surgery. However, mammography is not perfect, and is less effective for young women and dense breasts. Ultrasound: A non-invasive, radiation-free test that can be used for women of all ages and pregnant women. An excellent ultrasound machine can detect lesions of several millimeters in the breast and can assist in the evaluation of hyperplasia in the breast. Fiberoptic ductoscopy: Fiberoptic ductoscopy is an endoscope made of fiberoptic fibers that can penetrate into the tiny ducts of the breast to directly observe lesions and take biopsies of diseased tissue. It is mainly used in cases where the cause of nipple discharge is unknown and the lump cannot be detected clinically. It has great value in the diagnosis of early breast cancer in the ducts. With the help of ductoscopy, the source of the discharge and the nature of the microscopic lesion can be clarified. MRI: MRI is more accurate than x-ray and ultrasound in diagnosing the size and number of malignant tumors, and can detect tumors that are difficult to detect earlier. It is recommended that women with high-risk factors of breast cancer should combine with MRI to increase the possibility of early diagnosis of breast cancer and to create conditions for early treatment and increase survival rate. Breast Vacuum Assisted Minimally Invasive Rotational Excision System: Patients who would otherwise require an incision for a definitive diagnosis can be excised and removed with the help of this instrument using a 2-5 mm skin incision, guided by ultrasound or mammography, without damaging the appearance of the breast at all.
