Scientific understanding of breast cancer

Breast cancer is one of the major malignant tumors affecting women’s health, and its early detection is essential to improve the treatment effect and survival rate. Breast lumps, skin changes, nipple discharge, nipple and areola abnormalities, and enlarged axillary lymph nodes are common early symptoms of breast cancer; hence the need for vigilance. One, the inchoate omen of breast cancer 1, breast bump: Appear inside the breast indolence sex, quality of a material is harder, the edge is irregular, the surface is not smooth bump, it is the commonnest inchoate symptom of breast cancer. These lumps tend not to be easily pushed and may grow over time. 2. Skin changes: Breast cancer may cause breast skin abnormalities, such as “dimple sign” (skin depression) and “orange peel-like change” (skin edema, thickening, obvious depression of pores, orange peel-like). These changes are often due to tumor invasion of the suspensory ligament of the breast or subcutaneous lymphatic vessels. 3. Nipple discharge: Non-lactating women have bloody, serous or purulent nipple discharge, which may be one of the signs of breast cancer. This discharge is usually not accompanied by pain, but it should be highly valued. 4. Abnormal nipple and areola: When the tumor is located in or close to the deep part of the nipple, it can cause nipple retraction or elevation. At the same time, nipple skin itching, erosion, ulceration, scab, desquamation and so on may also be early symptoms of breast cancer. 5. Axillary lymph node enlargement: In the early stage of breast cancer, cancer cells may metastasize to axillary lymph nodes through lymphatic vessels, leading to lymph node enlargement. This swelling is usually painless, hard in texture, and less pushable. 2. Ways to prevent breast cancer 1. Healthy diet: maintain a balanced diet, eat more vegetables, fruits and whole grains rich in cellulose, and reduce the intake of high-fat, high-calorie foods such as fried foods. In addition, moderate intake of foods rich in vitamin D and calcium can also help reduce the risk of breast cancer. 2. Regular exercise: Regular physical exercise, such as fast walking, swimming, yoga, etc., at least 3-5 times a week, more than 30 minutes each time, can enhance the body’s immunity and reduce the risk of morbidity of breast cancer. Exercise also helps to control weight and avoid obesity, which is an important risk factor for breast cancer. 3. Regular screening: Adult women should undergo regular breast cancer screening, including breast self-examination, clinical physical examination and imaging examination (such as breast ultrasound, mammography, etc.). Breast cancer or precancerous lesions can be detected early through screening, so that timely and effective treatment measures can be taken. Once any of the above abnormal symptoms or signs are found, do not delay or deal with them by yourself, and go to a regular hospital immediately for examination and treatment

by a professional doctor.
