Statistics on women who have undergone mammograms reveal that the rate of female breast enlargement is 96%. Many women in this age group think that they are already menopausal and their breast glands are shrinking, so they will not get breast cancer again. In fact, women in this age group are not only likely to develop breast cancer, but also to miss the disease due to long-term neglect of breast examination. How to perform breast examination According to the experts in public health, the diagnosis of breast tumor should be based on a detailed medical history, including past history, menstrual and marital history and family history, followed by a general examination and finally a breast examination. 1.Visual examination ①Patients should take off their tops and face the light. ②Observe whether the breast is symmetrical and developed (such as youthful, hypertrophic, dysplastic, atrophic, etc.), and then observe whether there are any abnormalities such as bulging and sinking in various parts of the breast. ③Whether the skin of the breast is normal, and whether there is skin adhesion, edema, redness or rupture, etc. (iv) Whether the nipple area and size are normal, and whether there are indentations, fissures, erosions, ulcers, overflow and other lesions. The size of the areola, the depth of coloring, and the presence of redness, edema, and erosion. ⑤ The location, shape, and whether the breast swelling is broken, etc. The tumor is not easy to see if it is deep, but easy to see if it is superficial. (6) Whether the armpit and the upper and lower clavicle are full, and whether there are paramammary glands. 2.Palpation ①Check the healthy side first, and then check the affected side. Pay attention to gently pressing and rubbing with palms and fingers, do not use fingers to grasp and pinch. ②Check the axillary fossa for enlarged lymph nodes. If there are enlarged lymph nodes, it indicates that the lymph nodes have metastasis. ③Check the lymph nodes in the upper and lower clavicular fossa. If there are enlarged lymph nodes, it means that there may be distant lymph node metastasis. ④Breast examination, either in the lying or sitting position, starts from below the clavicle and touches gently in parallel in order to reach the lower border of the breast. If a mass is found, detailed records of the site, size, shape border, hardness, pressure pain and mobility of the mass should be recorded. In addition to the above, the contraction phenomenon of the breast and nipple should be noted. ⑤ Examination of nipple overflow: press gently from around the breast to the nipple, and then press the areola and nipple, and note whether there is fluid outflow, especially bloody fluid outflow. And note whether it is one milk duct opening or several milk duct openings.
