With the increasing modernization of society, the pace of life has accelerated significantly, making women’s life and work increasingly stressful, which on the one hand poses a great danger to their health, and on the other hand makes them gradually neglect their health status. Due to the influence of various factors from life, work and environment, breast diseases have become the main cause of health hazards for women, among which breast cancer has become the first malignant tumor incidence among women in some cities in China. Fortunately, breast cancer is one of the few malignant tumors that have been proven by research and practice to reduce mortality through screening. Early-stage breast cancer detected by screening has good treatment outcomes, good prognosis, and a much better quality of life for patients. Some patients with early breast cancer detected by screening can be spared from the toxic side effects of radiotherapy, and breast-conserving surgery can be performed for early breast cancer, which will give patients great psychological comfort and high quality of life. Screening for breast cancer is generally recommended for women starting at the age of 40, but for those with high risk factors for breast cancer, it is recommended to start screening earlier than 20 years old. What is a high-risk group for breast cancer? I think many women would like to understand. According to many sources, it is recommended that people with the following conditions should pay high attention to their breast health. People with obvious genetic predisposition to breast cancer, such as BRCA mutation carriers (positive BRCA mutation test), with obvious family history of breast cancer, etc. For example, you may understand well. Patients who have had previous radiation therapy to the chest for other cancers, etc.; 4. Patients with early menarche (<12 years old) or late menopause (>52 years old); those who have been menstruating for more than 35 years; those with short menstrual cycles (<21 days), low menstrual flow or long irregular periods; women with prolonged menopause; 5. Women who are not breastfeeding, have not given birth or have given birth too late (>35 years old) According to some data, the risk of breast cancer is 1.5 times higher for women who are not breastfeeding than those who are breastfeeding, 30% higher for those who have not given birth than those who have given birth, 3-4 times higher for those who have given birth to their first child at the age of 35 or older than those who have given birth under the age of 30, and higher for women who have repeated abortions. The risk of breast cancer in one side is 7 times higher than that in the other side; 7. Women with high estrogen level, such as long-term use of estrogen-containing drugs, frequent use of health products, food and drinks with high estrogen content, frequent use of skin care, beauty and breast enlargement products with high estrogen content, etc., are prone to breast diseases and breast cancer; 8. 9. Women who smoke, drink alcohol, work under pressure, lead an irregular life, are depressed for a long time and are repeatedly exposed to various kinds of radiation; 10. Women with a long history of benign breast diseases, especially those with a history of cystic hyperplasia of the breast, who have not received reasonable treatment. In view of the above factors, we remind women that if you meet one or more of them, it is necessary to conduct regular self-examination of your breasts and, if necessary, go to the hospital for examination, so that abnormalities can be detected and treated at an early stage.
