　　U.S. researchers recently claimed that women who have children later in life may be less likely to develop ovarian cancer danger.
　　
　　Researchers at the University of Southern California studied 477 ovarian cancer patients and 660 women of the same race, age and region. healthy Women surveyed found that women who gave birth to children later in life had a lower risk of ovarian cancer.
　　
　　A research report published in the recently published "Fertility and Sterility" magazine stated that women who give birth to children after the age of 35 have a 58% lower risk of ovarian cancer than women who have never given birth to children. Women who give birth early also have a lower risk of ovarian cancer, but not by much. For example, women who gave birth before the age of 25 had a 16% lower risk, and those who gave birth before the age of 30 had a 45% lower risk. Women who have given birth to four or more children have a 64% lower risk than women who have never had children.

　　Previous studies have suggested that late childbearing can also prevent women from developing Uterus Endometrial cancer. Researchers believe that because women produce large amounts of progesterone during pregnancy, progesterone is responsible for both cancer Has a certain inhibitory effect. Therefore, high concentrations of progesterone can kill cancer in its early stages. In addition, during childbirth, with the delivery of the placenta, the uterus is "cleaned" and those aging cells that may cause cancer are also removed.
