Older women should pay attention to the causes of breast cancer

The cause of breast cancer is the result of multiple factors working together under certain conditions. No single factor can explain the cause of breast cancer. Ladies, what are the causes of breast cancer? Let's ask experts to give us a detailed answer to the causes of breast cancer .

1. History of breast disease.

Data show that some non-proliferative benign breast diseases are related to the etiology of breast cancer. In addition, some proliferative breast diseases increase the risk of breast cancer, especially those with atypical lobular or ductal hyperplasia.

2. Pregnancy and breastfeeding history.

Pregnancy and breastfeeding history are also one of the causes of breast cancer. Early age of first birth can reduce the risk of breast cancer, and full-term pregnancy is a necessary condition for protective effects. However, whether the length of breastfeeding is a direct cause of breast cancer, research results are inconsistent. Some scholars believe that lactation for more than 5 years can reduce the risk of breast cancer by 30%; some scholars believe that more months of breastfeeding is an indirect manifestation of more parity, and after considering the effect of parity, the effect of breastfeeding disappears.

3. Age factor.

For the general population, the incidence and mortality risk of breast cancer increases with age. The risk of a 50-year-old woman being diagnosed with breast cancer in the next 10 years is 1/40; a 70-year-old woman is 1/25; and a 90-year-old woman is 1/8. However, because the incidence of other causes of breast cancer in older women is gradually increasing, the mortality rate of breast cancer after the age of 65 is not significantly increased.
