Why China's growth rate of breast cancer in the world?


Do you think breast cancer is far away from you?


Recently, the National Cancer Center released the "Status and Trends of Tumors in China 2017" report, the incidence of breast cancer ranked first in women with malignant tumors.


The British newspaper The Independent also pointed out that from 2000 to 2013, China's average annual growth rate of breast cancer was 3.5%, while the United States fell 0.4% over the same period.


A series of data is thought-provoking, listening to breast cancer out of reach, the actual close at hand. Today, medical technology continues to progress, we still can not control breast cancer ... ...


Lu Xu, deputy director of general surgery at Beijing Hospital, pointed out that the world every 26 seconds will add a case of breast cancer patients, he has been treated by the youngest breast cancer patients only 17 years old.


We invite the authority of experts, to remind you six reasons for breast cancer, teach you to properly protect the breast.


Interviewed experts


Chinese Academy of Medical Sciences Cancer Hospital Director Xu Binghe oncology

Breast cancer is about 10 years earlier than abroad


Lu Min, director of Breast Center of University of Southern California Medical School, said that North America, Northern Europe and Oceania are the areas with high incidence of breast cancer with white females predominantly; South America, southern Europe and Israel belong to the middle area; Asia is the low-lying area.


White American women's lifetime incidence of breast cancer was 13.1%, while the incidence of breast cancer in Asian women was 4% to 7%.


Although the incidence of breast cancer in Europe and the United States is high, the mortality rate is very low. The average 5-year survival rate of breast cancer in the United States is 90%, while that of China is only 73.1%.


The incidence of breast cancer in China is lower than that in western countries, but the growth rate ranks first in the world. Especially in Beijing, Shanghai, Guangzhou and other cities, the incidence is close to the level of developed countries in Europe and the United States.


Xu Binghe, director of Oncology, Cancer Hospital, Chinese Academy of Medical Sciences, summarized two major features of "Chinese-style" breast cancer:


Early onset of disease


The peak incidence of breast cancer in China aged 45 to 55 years old, as early as 10 years old than Westerners. Among them, relatively young patients, 35% of the age of about 15%.


Visiting late


In Beijing, for example, only 32% of patients in the first visit, 52% in two, and 13% and 2% in stages 3 and 4, respectively. In western countries, the proportion of patients in stage 1 exceeds 50%, and most patients can find early treatment as early as possible.


6 major causes of estrogen disorders


At present, the pathogenesis of breast cancer is not yet clear, but a large number of epidemiological studies found that human estrogen levels associated with breast cancer.


When estrogen levels continue to rise, or prolonged action, stimulation of mammary epithelial will enhance or prolong, in turn, induce cell evil STD change.


Causes female estrogen secretion disorders mainly due to the following six:


1 .High-fat diet


Eat too much Western fast food, big fish, cream cake, will lead to increased body fat.


Aromatase enzymes in fat more, the female body will be converted into male sex hormones estrogen, stimulate hyperplasia of breast cells, leading to malignant tumors.


2.Excessive drinking


After a large number of women drink alcohol, the secretion of prolactin will increase, stimulate breast cells, leading to hyperplasia and cancer.


Excessive male alcohol intake will make the liver inactivation of estrogen in vivo capacity weakened, the relative increase in estrogen levels, increased the incidence of breast cancer.


3.Delayed marriage and childbearing


Having multiple children reduces the risk of breast cancer. Studies show that women who are 35 years of age and younger at the birth of their first child usually have a protective effect from their pregnancy.


However, many Chinese women have to have late childbirth due to work stress.


4.Breastfeeding rate is low


Breastfeeding reduces the risk of breast cancer in women. An authoritative medical journal The Lancet evaluated low- and middle-income countries around the world and found that 6 months of exclusive breastfeeding was 37% compared with 20.8% for China.


5.Too much pressure


Stress can affect the level of various hormones, inhibiting the immune system to play a role.


An authoritative women's investigation found that nearly 95% of professional women were under various kinds of stress and 28% of women were scared of being "unable to adapt to competition."


6.lack of exercise


Women's physical activity less than previous generations.


According to a study published in the Journal of International Conduct Nutrition and Sports, between 1991 and 2011, the level of physical activity in adults in China dropped by nearly half and women were falling faster than men.


4 steps a month to do self-examination


Normal menstruation women, self-examination of the best time is menstrual cramps after the first 9 to 11 days, when more easily found lesions, postmenopausal middle-aged women free from time constraints, you can always check.




Facing the mirror, his hands drooping, carefully observe the size of both sides of the breast symmetry, with or without irregular protrusions, skin and nipple whether there are sunken or eczema .




Raise your left hand to the back of your head, check your left breast with your right hand, gently press the breast with your finger pulp, and feel if you have lumps.


Starting from the nipple to do circular clockwise direction, gradually outward (about three or four laps), until all the breasts check finished. Use the same method to check the right breast.


lie down


Lie down lying down, put down a pillow on his left shoulder, his right hand bent to the head, repeated "press" method, check the breasts on both sides.




In addition to the breast, but also check whether the underarm lymph nodes. Then thumb and index finger squeeze the nipple, with or without abnormal secretions.


Good habits of self-test light is not enough, there may still be due to improper personal practices delaying the disease. Suggested that life or self-test found abnormalities, to promptly consult a doctor.


Do five things to prevent breast cancer


Maintaining a good mood


Stress, bad mood is a relevant factor in breast disease, therefore, prevention of disease, we must first maintain a happy mood, to avoid long-term depression, anxiety and other negative emotions.


Wear underwear to liberate breasts


Underwear size is too small, it will oppress the chest, leading to mastitis or breast hyperplasia , and even increase the risk of breast cancer.


Experts suggest that the time to wear underwear does not exceed 8 hours a day. Selection, the preferred cotton underwear.


Size, the best between breasts and underwear can accommodate 1 to 2 fingers.


Eat more breast "like" food

Colored fruits and vegetables


A study by the International Agency for Cancer Research conducted on more than 90,000 women found that a plant-based diet can reduce the risk of breast cancer by 15%.


Peppers, tomatoes, eggplants, carrots, broccoli, and onions reduce the risk of breast cancer by eating eight to ten servings (80 to 100 grams each).


Dietary fiber


Research shows that dietary fiber helps prevent breast cancer. Dietary fiber helps the digestive system to remove waste regularly and helps the body to eliminate toxins and prevent it from damaging the body.


Whole grains and beans


Researchers found that beans and whole grains contain antioxidants that can help prevent many diseases. Eat more beans rich in dietary fiber (such as lentils) will reduce the risk of breast cancer, daily intake of 30 to 45 grams.


Good fat


Polyunsaturated fatty acids and monounsaturated fatty acids are called "good fats," and they are naturally found in foods such as olive oil, avocado, nuts, salmon, herring.


Omega fatty acids contained in "good fats" reduce the inflammatory response and play a role in reducing the risk of breast cancer.


In addition, the fungus, kelp, nuts, soy products and other foods are also good for breast health.


Improve bad habits


Reduce high-fat, fried diet, adhere to 4 hours a week of exercise, maintain a healthy weight (BMI 18.5 to 24). Ensure adequate sleep time, adhere to breastfeeding.


Quit smoking and drinking, studies have shown that women drink three times a week alcohol-induced breast cancer risk increased by 15%. Drink 1 alcoholic beverage daily, then the risk of breast cancer increased by about 10%.


Regular medical examination


Lu Min stressed that menarche, menopause late, over 35 years of age or over 35 fertility first child, have a family history of breast cancer or benign breast disease in women are high risk groups, but also to guard against breast cancer.
