Breastfeeding is the best combination of diet and thickness.
The prevention of breast cancer mainly involves nutritious diet, reproduction and breastfeeding, drinking, obesity, physical exercise, occupation and environment, heredity and family history. Zhang Binming introduced that with the decline of the proportion of grain, potatoes and beans in the food structure, the intake of animal protein and oil increased significantly, leading to the increase of diseases such as breast cancer. Therefore, it is necessary to change the eating habit of "high calorie and high fat". Food should be diversified, eat more fresh vegetables and fruits, light and low in fat, and the thickness should be well matched.
At the same time, women's mammary glands mature under the action of puberty ovarian hormones, while breast cells undergo physiological proliferation changes due to the periodic changes of hormone levels in the body every month and the increase of hormone levels during pregnancy. This form of cell proliferation and division is related to the termination of female menopause. The occurrence of breast cancer is closely related to many reproductive factors. Menstruation before 12 years old, amenorrhea after 55 years old, giving birth to the first child or childless after 30 years old all increase the risk of breast cancer. Breastfeeding has a protective effect on the occurrence of breast cancer. Zhang Binming suggested that the prevention of breast cancer should be a complete pregnancy before the age of 30, and suggested breastfeeding to avoid induced abortion or spontaneous abortion as much as possible.
Drink less and exercise more.
Alcohol intake will also increase the risk of breast cancer, and there is a certain relationship between alcohol intake and breast cancer risk. Studies have shown that the intake of 2.3 ~ 4.5 bottles of beer, 2.5 ~ 5.6 cups of fruit wine or 2 ~ 4 times of white wine per day can increase the risk of breast cancer by 465,438+0%. Zhang Bin said that obesity may also increase the risk of breast cancer, especially for obese postmenopausal women. The ovaries of postmenopausal women no longer produce estrogen, and the amount of estrogen produced by peripheral fat has a more significant effect on the whole body estrogen level of postmenopausal women than that of premenopausal patients.
Physical exercise is also related to the risk of breast cancer, and premenopausal young women benefit the most. Zhang Binming introduced that strengthening physical exercise in adolescence can reduce the incidence of adult breast cancer. The effect of proper physical exercise on the incidence of breast cancer in adults may be related to reducing obesity, especially in postmenopausal women. Women who exercise 3-4 times a week are less likely to get sick than women who don't exercise.
It is very important for high-risk groups to have regular physical examinations.
"Women engaged in beauty, pharmaceutical manufacturing and other occupations are also potential high-risk groups of breast cancer." Zhang Bin said that some breast cancer screening and treatment methods can also induce and aggravate the occurrence of breast cancer, especially those who receive treatment before the age of 20, and the risk of breast cancer will increase.
Hereditary breast cancer accounts for 5% ~ 7% of all breast cancer cases. The risk of lifelong breast cancer of BRCA 1 and BRCA2 mutation carriers is 56% ~ 85%. BRCA 1 and BRCA2 gene mutations are the main causes of hereditary breast cancer. Zhang Binming emphasized that people with a family history of breast cancer should attach great importance to it, but don't panic. Compared with the general population, regular physical examination is particularly important.
