Beautiful curves and the source of life are the charms that breasts bring to women, but at the same time, they also increase the risk of a disease. With the improvement of living standard in our country’s economic development, the incidence of breast cancer is increasing due to stress, pollution and the change of reproductive pattern; the age of onset of breast cancer in China is on a younger trend, with the peak age of onset occurring between 40 and 45 years old, which has become the main killer threatening women’s health. Therefore, women should raise their awareness of self-care, care for their breasts and have regular checkups. Care for the breasts should be throughout a woman’s life: 1. For newborns, due to the influence of maternal hormones female babies may have bilateral breast swelling after birth, and even a little fluid secretion, but this is a normal physiological phenomenon, 1-2 weeks after birth the baby’s body from the mother’s hormones will be metabolized, the swelling of the breast will disappear on its own. So at this stage do not follow our old saying to milk the head, which may instead damage the tender mammary tissue, and even cause infection and inflammation. 2, adolescent girls, breasts as a second sex characteristics will gradually develop, the initial period can not wear a bra, fully developed to wear a suitable bra, loose and tight, with the development of timely replacement. At the same time, pay attention to the standing posture, active exercise will help breast beauty and reduce the occurrence of breast disease in adulthood. Mothers should be concerned about the breast health of adolescent girls. If you find a lump there is no need to panic, find a doctor to look at it, do not delay the consultation because of shyness. 3. After adulthood, we generally recommend annual breast health checkups. Initial palpation by a professional doctor can detect lumps of 1cm or more, and smaller lesions can be found with the help of instruments. At present, a reasonable combination of breast ultrasound and mammography can maximize the detection of early lesions in the breast. It is recommended that ultrasound can be the first choice for general checkups after the age of 30, and can be considered in combination with mammography after the age of 40. 4. During pregnancy and childbirth, the breast has to bear the burden of breastfeeding, and the most common disease at this time is mastitis, which is mainly characterized by local redness, swelling, pain and sometimes fever. It is important to pay attention to the baby’s oral hygiene, washing the breast before breastfeeding, correct feeding posture, preventing stagnation of milk and nipple breakage. 5. Early stage of breast cancer may not have any symptoms. Common symptoms of breast cancer include: lumps in the breast, or local thickening in the breast, overflowing blood from the nipple, swollen lymph nodes in the armpit, etc. Therefore, if you find any of the above conditions, you should pay attention to the breast hygiene, washing the breast before breastfeeding, correct feeding posture, preventing stagnant milk and broken nipples. Therefore, if you find any of the above, you should see a breast specialist to determine if there is any problem. 6. What if you have breast cancer? Don’t be frustrated, breast cancer doesn’t necessarily mean removal of breast, treatment is expected to still preserve the curves of women.
