Xiao Yi is a hardworking woman, from the student days is very strong, with excellent grades into a famous university in China, after graduation to continue to study abroad, 2 years ago returned to China to join a well-known enterprise as a senior executive. While her career was booming, her age also reached several 30s unconsciously. Just when her friends and relatives were anxious about her lifelong event, her marriage came unexpectedly and she was lucky to find her husband soon. She is suffering from breast cancer and it is in the middle and late stage ……. What caused Xiaoyi to suffer from serious breast cancer at a young age? According to the survey data of the Center for Disease Control and Prevention, in recent years, the incidence of female breast cancer in China is growing younger, especially in large and medium-sized cities, and the average age of onset is moving forward significantly, about 10 years earlier than that of Western women. Compared with the 1980s, the age of menarche is 1 to 3 years earlier for women in China, and modern urban women are pursuing career success too much, marrying late and having children later, giving up breastfeeding or even childbirth in order to “enjoy life to the fullest”, and most of these women are highly intelligent and educated, with higher positions and incomes. In contrast, irregular life, stressful work and neglect of self-care are the hidden killers that lead to the increase of breast cancer incidence. So what kind of lifestyle is good for the prevention of breast cancer? First of all, we should clarify whether we belong to the high-risk group of breast cancer. Clinical medicine classifies women with family history of breast cancer, early menarche or late menopause, advanced childbirth, overweight, stressful work, irregular life, long-term use of hormonal drugs and long-term exposure to toxic and harmful substances as the high-risk group of breast cancer. Secondly, we should advocate a healthy lifestyle, eat less high-fat and high-protein foods, limit the intake of meat and animal fat, limit the intake of salt to less than 6 grams per day, and take fewer nutritional supplements and supplements, especially drugs containing estrogen. Eat more whole grains, beans and other roughly processed foods, a variety of brightly colored fresh vegetables and fruits, and a variety of mushrooms, and drink tea regularly. Maintain an appropriate weight and keep it stable to avoid being underweight or overweight. Regular and appropriate physical exercise. Quit smoking and limit the intake of alcohol. Ensure that you get enough sleep daily, etc. The third step is that young women should do monthly breast self-examinations and semi-annual mammograms to ensure that abnormalities in the breast can be detected and dealt with early. At the same time, for the high-risk group, they should also cooperate with at least once a year breast ultrasound examination, mammogram and tumor marker examination. Only by doing the above three things, implanting a healthy concept of life, maintaining a healthy lifestyle and paying attention to their breast condition regularly, modern women can stay away from the devil of breast cancer and truly have a healthy and beautiful life.
