9 types of people most vulnerable to breast cancer

　　Type 1: Repeated abortion surgeries

　　Repeated abortions can cause female suffer from breast cancer The possibility of disease is greatly increased. A study shows that spontaneous abortion does not increase the risk of breast cancer; women who have had an induced abortion before the age of 18 have a 110% higher risk than those who have not had an induced abortion.

　　This is because every time a pregnant woman has an abortion Postpartum When the pregnancy is suddenly interrupted, the hormone levels in the body drop suddenly, causing the newly developed mammary glands to suddenly stop growing, causing the acini to become smaller or even disappear, and the mammary glands recover.

　　This recovery is usually incomplete and can easily cause breast lumps and pain, which can induce breast cancer. disease , repeated breast lesions can become a cause of breast cancer.

　　Therefore, modern women should improve their awareness of self-care and advocate late marriage and late childbearing, but it should not be too late. It is best for women to get married before the age of 28. Breastfeeding, reasonable diet and physical activity should be promoted exercise Live a scientific lifestyle, keep an open mind, avoid depression and anger, and maintain good physical and mental health healthy . These are essential to prevent and reduce the incidence of breast cancer.

　　The second type of person: Women who marry late, have children, and do not breastfeed are prone to breast cancer.

　　Data show that women who have never given birth have a 30% higher risk of contracting the disease than women who have given birth; women who are not breastfeeding have a risk of contracting the disease that is more than 1.5 times higher than breastfeeding women; first-time pregnant women over 35 years old have a relative risk of breast cancer that is 3 to 4 times higher than those under 30 years old!

　　The third type of person: Breast hyperplasia Not healed for many years

　　Breast hyperplasia has four strange symptoms: one is lumps with unclear edges in the breasts; the other is premenstrual breasts. distended pain , even radiating to the shoulders or back, and sometimes it is very uncomfortable; third, there is the possibility of cancer, especially in the cystic hyperplasia type, and it is said that its cancer rate is 0.35%; fourth, the treatment time is long, and the hyperplastic tissue has poor sensitivity to drugs, or in other words, there is still a lack of specific drug treatment. Therefore, breast hyperplasia is still a problem for many doctors and even more confusing for many women in today's modern science.

　　The fourth type of person: menarche before the age of 13 or menopause Night

　　Women's early menarche (menstruation before the age of 12), late menopause (menopause after the age of 50), and long menstruation (more than 35 years) are all recognized risk factors for the disease. Statistics show that for every 4 to 5 years of age at menarche, the risk of breast cancer doubles. People who have menarche between 13 and 15 years of age are 20% less likely to develop breast cancer than those under 12 years old.

　　People who undergo menopause under the age of 55 have a lower incidence of breast cancer. People who are older than 55 years old at menopause have about twice the risk of menopause than those who are younger than 45 years old.

　　The fifth type of person: Obesity or excessive intake of fat

　　Swedish and American scientists recently jointly announced the results of a study showing that young women with anorexia have a lower risk of breast cancer. This shows that women's caloric intake in early life may play a greater role in the formation and development of breast cancer later.

　　Researchers also caution that anorexia is a serious mental illness that can lead to life-threatening complications. Therefore, women should not mistakenly interpret the results of this study to mean that starvation can avoid breast cancer. Their findings only explain possible mechanisms by which breast cancer develops.

　　Researchers looked at breast cancer in 7,303 Swedish women who were hospitalized for anorexia between 1965 and 1998. The women surveyed were all under 40 years old, and most of them suffered from anorexia before the age of 20.

　　Researchers found through investigation that the incidence of breast cancer in young women hospitalized for anorexia was only half that of women without anorexia. The researchers said that some studies in the past have shown that weight gain is one of the causes of breast cancer.

　　These studies, mostly based on animal experiments, show that drastically limiting caloric intake can have anti-aging effects, including reducing the occurrence of cancer and extending lifespan.

　　The sixth type of person: depressed, often angry, and in a bad mood

　　The seventh type of people: Repeated and long-term exposure to various types of radiation (multiple radiation, computers, mobile phones, etc.)

　　electromagnetic radiation. The breast is a tissue that is more sensitive to the carcinogenic activity of electromagnetic radiation. When young, the breast is in the active stage of mitosis and is most sensitive to the carcinogenic effects of electromagnetic radiation.

　　The eighth type of people: those with a family history of breast cancer, excluding genetic causes and environmental factors

　　A recent study by British scientists showed that one-third of breast cancer patients are caused by genetic inheritance.

　　Scientists from the University of Cambridge recently published a report at the annual meeting of Cancer Research UK, saying that they found that if the body's BRCA1 and BRCA2 genes mutate, the chance of developing breast cancer will increase to 70% to 80%.

　　However, they found that these two gene mutations accounted for only 5% of all breast cancer cases, and other women who develop breast cancer due to hereditary disease develop the disease because of more complex gene combinations.

　　Currently, scientists at the University of Cambridge are conducting a £1.7 million (approximately $3.3 million) project to search for the complex genetic factors that lead to breast cancer. Scientists estimate that it may be an unspecified combination of more than 10 genes that increases a person's chance of developing breast cancer.

　　Type 9 people: commonly used hormone drugs or cosmetics

　　Some drugs, such as antihypertensive drugs reserpine, phenothiazoles, and steroid drugs, can increase the prevalence of breast cancer. Some health products, skin care products, and cosmetics contain carcinogenic ingredients. Evidence-based medicine shows that hormone replacement therapy for women during menopause increases the risk of breast cancer, so women should not supplement estrogen and progesterone casually.

　　Phthalates are a class of chemicals that have a softening effect. It is commonly used in toys, food packaging materials, medical blood bags and hoses, vinyl flooring and wallpaper, cleaners, lubricants, personal care products such as nail polish, hair sprays, soaps and shampoos, and hundreds of other products.

　　Among cosmetics, nail polish has the highest phthalate content, and many cosmetics also contain these substances in their fragrance ingredients. Professor Cheng Changmei, a professor at the Department of Chemistry at Tsinghua University, said that this substance in cosmetics will enter the body through women's respiratory system and skin. If used excessively, it will increase the chance of women suffering from breast cancer and will also harm the reproductive system of their future male babies.
