The first group, early menarche or late menopause before the age of 13
Early menarche (menstruation before age 12), late menopause (menopause after age 50), and long periods (greater than 35 years) are all recognized risk factors for the development of breast cancer in women. Statistics show that for every 4-5 years earlier the age of menarche, the chance of breast cancer increases by a factor of 1; those who have menarche at the age of 13-15 years or older have 20% less chance of breast cancer than those who are under 12 years old. The incidence of breast cancer is lower in those who are under 55 years of age at menopause. Those with menopause age greater than 55 years old have about 1 times more risk than those with menopause age less than 45 years old.
The second type of people, mastopexy does not heal for years
Mammary gland hyperplasia has four strange temperaments: one is the appearance of lumps with unclear edges in the breast; second, premenstrual breast swelling and pain, even radiating to both shoulders or back, and sometimes uncomfortable; third, the possibility of cancer, especially those belonging to the cystic hyperplasia type, which is said to have a cancer rate of 0.35%; fourth, the long treatment time, poor sensitivity of the hyperplastic tissue to drugs, or, so far, the lack of specific drugs for treatment. Therefore, breast hyperplasia is still a problem for many doctors and more confusing for many women today with the advanced modern science.
The third type of people, repeated abortions
Repeated abortions can make women more likely to develop breast cancer. A study showed that spontaneous abortion does not increase the risk of breast cancer; however, women who had an abortion before the age of 18 had 110% higher risk than those who did not have an abortion. This is because after each abortion, the pregnancy is abruptly interrupted and the hormone level in the body suddenly drops, causing the newly developed mammary glands to suddenly stop growing, making the alveoli smaller or disappearing, and the mammary glands to recover.
This recovery is usually incomplete and can easily cause breast lumps and pain, which can lead to breast diseases and repeated breast lesions can become a cause of breast cancer.
The fourth type of people, women who marry late and have children late are prone to breast cancer
According to the data, the risk of the disease is 30% higher for women who have never had children than for women who have had children; the risk of the disease is more than 1.5 times higher for women who are not breastfeeding than for women who are breastfeeding! Breast cancer is one of the malignant tumors with the highest incidence rate in the world, and the incidence rate in China is relatively low, but it is increasing at a rate of 2-5% per year.
It is estimated that there are about 100,000 breast cancer patients and 40,000-50,000 deaths per year in China, so the mortality rate is relatively high. Breast cancer in China is characterized by a relatively rapid rise and an early age trend. It is known that the peak incidence of breast cancer in China is 10-15 years earlier than that in Europe and the United States, and the peak incidence in Europe and the United States is 56 years old, while in China it is 45-49 years old. The main reason is the ethnicity.
However, the youthfulness of breast cancer is also related to the improvement of our living standard. Studies show that a high-fat and low-fiber diet can increase the incidence of breast cancer by more than 4 times; a young woman who drinks alcohol 3-6 times a week, each time based on 250 ml of beer or 185 ml of spirits, will increase her risk of breast cancer by 30%-60% in the future.
The fifth type of people, not breastfeeding or breastfeeding too long
If you have dimples on your face, it may make you more charming, but if you suddenly have dimples on your breasts, you may have breast cancer. Most of the breast cancers do not have obvious pain, but in the early stage of development, about 5% of people may have bloody nipple discharge.
”Dimple sign” prefers seven kinds of women: firstly, people with family history of cancer, especially those whose mothers or sisters have suffered from breast cancer; secondly, people with early menarche (below 12 years old) and late menopause (above 55 years old); thirdly, people with certain benign breast diseases; fourthly, people who often receive radiological chest X-ray or chest X-ray; fifthly, people who have never breast-fed, never given birth or given birth. Those who have never breastfed, never had children or had late childbirth or many miscarriages; six, women with high breast density and solid texture; and seven, women who are particularly obese above the waist and whose waist circumference is similar to their hip circumference.
Lumps in the breast are the most important and basic symptom of breast cancer. Lumps are usually found in the upper outer part of the breast, usually about 2 cm in size, and are irregular spherical lumps. In addition, changes in breast contour and curvature and nipple shape, such as bilateral breast asymmetry and nipple invagination, are also signs of breast cancer.
The sixth type of people, commonly used hormonal drugs or cosmetics
Some drugs, such as blood pressure medicine rifampin, phenothiazole, etc. 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. Evidence-based medicine shows that hormone replacement therapy during menopause increases the risk of breast cancer, so women should not take estrogen or progestin supplements casually.
Phthalates are a class of chemicals that act as a softening agent. It is commonly used in toys, food packaging materials, medical blood bags and tubes, vinyl flooring and wallpaper, cleaning agents, 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 fragrance ingredients in cosmetics also contain the substance. Professor Cheng Changmei, a professor of chemistry at Tsinghua University, said the substance in cosmetics can enter the body through women’s respiratory system and skin, and if used excessively, it can increase women’s chances of developing breast cancer and also endanger the reproductive system of their future baby boys.
The seventh type of people, obesity or excessive intake of fat
The results of a recent study jointly published by Swedish and American scientists show that young women with anorexia have a lower risk of breast cancer. This suggests that women’s caloric intake in their early years may have a greater role in the formation and development of breast cancer later in life.
The researchers also cautioned that anorexia nervosa is a serious psychological disorder that can lead to the development of several life-threatening complications. Therefore, women should not make the mistake of interpreting the findings of this study to mean that taking a starvation approach will prevent them from developing breast cancer. Their findings only explain the possible mechanisms of breast cancer formation.
The researchers investigated 7,303 Swedish women who were hospitalized with anorexia nervosa between 1965 and 1998 for breast cancer. All of these women surveyed were under the age of 40, and most of them suffered from anorexia nervosa before the age of 20.
The eighth type of people, mental depression, often angry, bad mood
Mood depression may be related to the high-intensity life pressure at the moment. Many women have developed bad habits such as unreasonable dietary structure, poor lifestyle habits and excessive life stress. Bad lifestyle habits bring depressed spirits, which in the long run lead to acidification of the physique and a decline in body functions, resulting in poor chi and blood, endocrine hormone imbalance, menstrual disorders and other phenomena thus causing breast disease, namely mastopathy. If not treated with intervention, breast cancer may be induced.
The ninth type of people, repeated long-term exposure to various kinds of radiation (multiple radiation, computers, cell phones, etc.)
Electromagnetic radiation. Breast is the tissue that is more sensitive to the carcinogenic activity of electromagnetic radiation. The breast is the most sensitive to the carcinogenic effect of electromagnetic radiation at the mitotic activity stage when you are young.
The tenth type of people, with a family history of breast cancer excluding genetic causes and environmental factors
A study by British scientists recently showed that one-third of breast cancer patients are genetically predisposed to the disease. Scientists from the University of Cambridge recently reported at the annual meeting of the British Institute of Cancer Research that they found that if the body’s BRCA1 and BRCA2 genes are mutated, the chances of developing breast cancer increase to 70 to 80 percent. However, they found that the two gene variants accounted for only 5 percent of all breast cancer cases, and that other women who developed breast cancer because of genetic predisposition developed the disease because of a more complex combination of genes.
