Breast cancer attacks women's health. Doing one more thing can reduce the incidence rate.

Breast cancer is showing a trend of being diagnosed at a younger age, and there are now even cases of high school students suffering from breast cancer. Judging from the current situation, the younger age of breast cancer is related to the excessive stress on young women and irregular diet and lifestyle. The hormones contained in cosmetics are also closely related to the induction of breast diseases. Therefore, female friends should understand the causes of breast cancer and take measures to prevent it.

Beware of the 6 major causes of breast cancer

Of course, breast cancer is not just caused by a single factor such as diet, stress, or cosmetics, but is the result of a combination of many factors.

1. Genetic factors

Clinical data from family history surveys show that the incidence of breast cancer is higher in women with a family history than in those without a family history. Especially for patients with bilateral breast cancer and those who develop the disease at a young age, the risk of developing breast cancer is 9 times that of ordinary women. This may be related to genetic factors, which make them susceptible to breast cancer and have internal causes of the disease.

2. Breastfeeding

Breastfeeding can reduce the risk of breast cancer, and the longer the breastfeeding period after the first birth, the lower the risk.

3. Estrogen and contraceptive drugs

Hormones play an important role in the development of breast cancer, and the relationship between long-term use of contraceptives and estrogen and the development of breast cancer is still under study.

4. Fertility factors

The incidence of breast cancer increases with the delay of the age of first birth. For example, the incidence of breast cancer in women who give birth to their first child at full term before the age of 20 is only one-third of that in women who give birth after the age of 30.

5. Dietary factors

There is a certain relationship between a high-fat diet and the occurrence of breast cancer. With the change of eating habits and the increase in the intake of high-fat foods, the incidence of breast cancer in urban women in my country has gradually increased, especially in some large cities. The incidence of breast cancer in women has reached the same level as that in Europe and the United States.

6. Obesity

Obese postmenopausal women have an increased risk of breast cancer. Therefore, older women should control their weight appropriately and eat less meat, fried eggs, butter, cheese and animal fat.

Walking reduces breast cancer risk

A new study finds that exercise can significantly reduce the risk of breast cancer. Moreover, just by taking a moderate walk, you can reduce your risk of breast cancer by up to 42%.

The researchers collected data from 79,124 women over an 11-year period. These women all ran or walked regularly, and the researchers recorded their weekly running or walking distance, chest size, weight, height and other data. The analysis results showed that none of these people had developed breast cancer since the beginning of the experiment.

The researchers also found that women who met the CDC's current aerobic exercise guidelines of 2.5 hours of moderate-intensity exercise or 1 hour 14 minutes of vigorous-intensity exercise per week were 42% less likely to die from breast cancer than their peers who did not meet the guidelines. This conclusion still holds true even if the impact of different body mass index (BMI) is eliminated.
