Breast cancer is a common malignant tumor that seriously endangers women’s physical and mental health, not only endangers patients’ lives, but also causes the destruction of female sexual organs.
The incidence of breast cancer has been among the highest in the world since the late 1970s. Since the late 1970s, the incidence of breast cancer has been ranked the first among female tumors worldwide and is increasing at a rate of 2.4% per year. In major cities such as Shanghai, Beijing and Tianjin in China, breast cancer has become the first malignant tumor among women. The exact cause of breast cancer is still unclear, and the occurrence and development of breast cancer cannot be explained by a single factor, but it is generally believed that the occurrence of breast cancer is related to the following factors Early menarche and late menopause: The relative risk of breast cancer increases 2.2 times when the age of menarche is less than 12 years old compared to more than 17 years old. The age of menopause is greater than 55 years old, and the risk of breast cancer is 1 times higher than that of those younger than 45 years old. Early menarche and late menopause are the two main risk factors for breast cancer. Genetic factors: A study found that women whose mothers had bilateral breast cancer before menopause have 9 times higher risk of breast cancer than the average woman, and the average age of breast cancer in the second generation of breast cancer patients is about 10 years earlier than the average person. The average age of the second generation of breast cancer patients is about 10 years earlier than that of the general population. Women who have sisters with breast cancer have three times the risk of the general population. It is important to emphasize that breast cancer is not directly inherited, but is a “cancer quality” inheritance, and relatives of breast cancer patients are not necessarily affected by breast cancer, but are more likely to develop breast cancer than the general population. Marriage and childbirth: Epidemiological studies show that women who are married but not pregnant at the age of 40 or have their first child after the age of 35 are also unfavorable factors, but the risk of breast cancer in unmarried people is 9 times higher than that in married people. Experts believe that childbirth has a protective effect on the breast, but only for those who had a full-term birth before the age of 30. Recent studies have concluded that breastfeeding has a protective effect on the occurrence of breast cancer, mainly in premenopausal women. IV. History of previous breast disease or surgery: Those who have had breast cancer on one side have high risk factors for the opposite breast, especially those with pathologically diagnosed lobular carcinoma in situ or multifocal carcinoma. Pathologically confirmed cystic hyperplasia of the breast, especially those containing active ductal epithelial atypical hyperplasia or papillomatous structures or complex sclerosing adenopathy.
History of multiple surgeries for benign breast tumors is also a high risk factor for breast cancer. V. Ionizing radiation: The breast is a tissue more sensitive to the carcinogenic activity of ionizing radiation. When young, the mammary gland is the most sensitive to the carcinogenic effect of ionizing radiation in its mitotic activity stage, and the effect of ionizing radiation is cumulative, and multiple small dose exposures have the same degree of risk as one large dose exposure, with a dose-effect relationship. Among the survivors of the atomic bombing in Nagasaki, Japan, the proportion of breast cancer increased significantly, and those who received chest radiotherapy during childhood and adolescence also had an increased chance of breast cancer when they grew up. Unhealthy eating habits: The incidence and mortality rate of breast cancer has a strong relationship with the amount of digested fat per capita. The high income of some company employees leads to a high standard of living, resulting in an unscientific and unhealthy “high-calorie, high-fat” diet, which leads to a much higher incidence of breast cancer. Unhealthy lifestyle: Some female white-collar workers who have been working in office for a long time sit more and move less, lack of exercise and less exposure to sunlight. Most professional women, due to their work, spend a long time with their brassieres tightly closed, rarely giving their breast glands “loose”; some professional women are forced to live a single noble or dinky life due to the pressure of work or the pursuit of career success, without a family and without children. Women who have had multiple abortions, or women with chaotic sex lives and long-term sexual disharmony. These factors are related to mastopathy. VIII. Mental depression and excessive tension: According to the survey, introversion, long-term mental depression and unhappy early life are important factors leading to cancer. Young urban women face fierce competitive pressure and their spirits are in a state of stress and tension for a long time, leading to emotional instability and lack of peace. These mental factors together with bad life and work style cause further damage to the breast. IX. Hormones: Breast cancer is related to the imbalance of human endocrine balance. Among the various endocrine factors, the most important ones are estrogen and progesterone. Research results show that estrogen stimulates excessive proliferation of breast gland epithelial cells, which is an important cause of breast cancer, and the frequent use of hormone products and hormone replacement therapy during menopause can increase the risk of breast cancer. Drugs: Some drugs such as antihypertensive drugs like reserpine and phenothiazole and steroidal drugs have the effect of increasing the prevalence of breast cancer. Some health products, skin care products and cosmetics contain cancer-causing ingredients and should be used with special caution. In addition, harmful ingredients in the air, residual pesticides on vegetables and fruits have different degrees of carcinogenic ingredients. Warm Tips: Proper understanding of many high-risk factors of breast cancer can help us to stay away from the pain of breast cancer, if unfortunately women with the above-mentioned breast
However, it should be noted that the risk of breast cancer for women with the above mentioned risk factors is only increased, not necessarily, nor does it necessarily have a causal relationship, that is to say, having these risk factors, even if all ten risk factors are present, does not necessarily mean that breast cancer will occur, because women who have breast cancer are after all individual, and they are not necessarily the same. After all, women who have breast cancer are an individual, a very small minority, so there is no need to be too nervous. We suggest that regular self-examinations and regular hospital examinations are necessary for people with high risk factors for breast cancer because most of the early stage breast cancers are curable and do not significantly affect the quality of life of patients.
