We often see female celebrities die because of breast cancer, breast cancer has become the number one killer of women, as women should always pay attention to their breast health and be alert if there is any abnormality! Early prevention! Early detection! Early detection and treatment! What are the early symptoms of breast cancer? Will there be pain in the early stage of breast cancer? 1. Nipple overflow: If blood, plasma, milk or pus flows from the nipple during non-pregnancy period, or milk still flows out after stopping breastfeeding for more than half a year, it is called nipple overflow. There are many causes of nipple overflow, and common diseases include intraductal papilloma, breast hyperplasia, ductal dilatation of the breast and breast cancer. Unilateral hemorrhagic overflow from a single hole should be further examined, and more attention should be paid if accompanied by a breast lump. 2. Change of breast whorl: When the lump is large, there may be local elevation of the breast and enlargement of the mammary gland. When the tumor involves the skin or pectoral muscle, it can make the breast harden and shrink. When the patient sits upright, the affected breast can be raised. 3, nipple invagination: There are several reasons for nipple invagination: clothing is too tightly bound, especially women’s underwear is too tight during breast development; improper use of bras, too small, too tight, used too early, etc.; genetic factors. Skin changes: Most breast diseases do not have any skin changes, acute mastitis often has skin redness, breast tuberculosis or plasma cell mastitis may have skin ulcers or fistulas, breast cancer skin may appear wrinkled or sunken to form a “dimple”. If the skin around the nipple has repeated eczema and itchy skin that does not heal, it may be Paget’s disease, which is a special type of breast cancer. 5. Redness/heat: deepening color and heat of nipple and areola, please pay attention to the cupping circle, all kinds of TCM stunts are here. It indicates that there may be hyperplastic lesions or cystic hyperplastic lesions in bilateral or unilateral breasts, or accompanied by increased estrogen level in the body. 6.Lumps: It is the first symptom of breast cancer. Most lumps are located in the outer upper quadrant, followed by the inner upper and nipple areola area, and less frequently below. The size of lumps varies, with 2 to 3 cm being the most common size. The lumps are mostly round or ovoid, with poorly defined borders, generally hard nodes, and poor mobility. 7, small dots: breast “dimples” is the performance of breast suspensory ligament involvement. Chronic inflammation of breast, fat necrosis, subcutaneous thrombophlebitis and post-operative scar contracture may cause skin dimpling. 8.Pain: Most breast cancer patients lack pain symptoms. Due to the less occurrence of pain, breast cancer is not easily detected early. Pain is often manifested as tingling, swelling or hidden pain in the breast, and periodic pain may also occur if the cancer is accompanied by cystic hyperplasia in the breast.
