Breast cancer screening for Chinese women is a must, and many doctors have found that many women have specious or even completely wrong ideas about breast cancer in their clinics and medical consultations. Therefore, it is of long-term significance to clarify women’s wrong and ambiguous concepts about breast cancer, so that more women can join the ranks of “Caring for Yourself, Caring for Your Breasts”. Myth 1: Breast cancer is not a contagious disease and it is not hereditary. Although breast cancer is not an infectious disease, it is hereditary. If there is a family history of breast cancer, and if more than one person in the immediate family has had breast cancer, then the likelihood that I will develop breast cancer is greater than that of the average woman. About 10% of breast cancer is hereditary. Myth 2: After being cured, breast cancer patients do not have to worry about getting the disease again. Patients who have had breast cancer before or have a history of benign breast tumors are at risk of developing new breast cancer. Although early-stage breast cancer enters the stable stage after 5 years of cure and recurrence is unlikely, new breast cancer cannot be ruled out. Patients who have had breast cancer in one breast have a 5-7 times higher chance of having cancer in the opposite breast than normal people. According to preliminary statistics, 10 years after the cure of breast cancer patients, the chance of new breast cancer is 6%, 20 years later is 12%. Myth 3: As women get older, especially after menopause, they will not develop breast cancer. Women after menopause are still at risk of developing breast cancer. Breast cancer is diagnosed in patients ranging in age from 17 to 92. Myth 4: In order to improve the quality of life, many women apply estrogen to control menopausal symptoms. Many women’s health products on the market nowadays contain a certain amount of estrogen, which is a “double-edged sword” that can prolong women’s “puberty” but also bring about breast ductal epithelial cell hyperplasia and even cancer. Women who have been using estrogen for many years may not have any abnormalities in the short term, but the risk of breast cancer is greatly increased. Myth 5: Men don’t get breast cancer, and breast cancer is the “patent” of women. Breast cancer can occur wherever there is breast tissue, and men also have breast ductal epithelial tissue, which can also become cancerous. However, the incidence of breast cancer in men is very low, about 1% of the incidence of breast cancer in women. Having children and artificial breastfeeding are beneficial in preventing breast cancer. Breasts are like plants that go through the whole process of spring, fall, blossoming and dying in order for it to grow more healthily. Childbearing and breastfeeding, which are the blossoming and dying of the breasts, will promote self-regulation of the breasts and strengthen their immunity. Women who have had childbearing experiences, especially multiple childbearing experiences, are far less likely to develop breast cancer than those who have not had children. Our country currently promotes the one-child system, and for women, breastfeeding is beneficial to both the baby and the mother. Little girls in their teens are also at risk for breast cancer. Estrogen is the main cause of breast cancer. Due to the improvement of living standards, early sexual maturity is common among children in the country, and therefore breast cancer patients have begun to show a trend of under-ageing. Women who have their first menstrual period before the age of 12 or stop menstruating after the age of 55 have a relatively high chance of developing breast cancer because their bodies are exposed to estrogen for a long period of time. Eating too much greasy food and being obese are prone to breast cancer. Medical experts believe that the development of breast cancer is directly related to the body’s intake of calories. It is recommended that women eat less greasy food, especially as little animal fat as possible, and maintain a normal body weight. If you take 70 kilograms as the standard weight, every 10 kilograms increase, the incidence of breast cancer increases by 20%, and every 10 kilograms increase in the weight of women around 60 years old, the risk of breast cancer will increase by 80%.
