Women who recently gave birth has a higher chance of developing breast cancer, a new study suggests.
A research group led by the University of North Carolina Lineberger Cancer Center found out that new mothers have a risk of getting breast cancer until 20 year passes after the birth. According to past research, scientists and doctors believed that women who have given birth have less risk of developing breast cancer. But this study busted the past research.
The risk is at peak within the five years of childbirth and persists till 24 years after the birth. Breastfeeding has nothing to do with it.
Women should not panic after reading finding out this study.
“The overall risk of breast cancer is low during reproductive years and, even with this increase, the risk is still low among women who have had children recently,” Hazel Nichols, Ph.D., study author.
She added, ”Breast cancer risk is not determined by one factor alone. We need tools to help women and providers put information from a women’s complete history: her age, her family structure, whether others in her family have had breast cancer, her lifestyle, to help make decisions around when to start participating in mammography screening programs.”
After analyzing 15 prospective studies around the world, the researchers concluded that women who had a child recently are more prone to breast cancer than women who are childless. This was published in Annals of Internal Medicine.
Breast cancer is common in women who have a family history of breast cancer.
Women who are above 50 are more likely to get breast cancer than younger women. If women had their child before or around the age of 25, then there was no so much risk of getting breast cancer. Women have the highest risk of getting breast cancer in five years after the childbirth. The researchers suggested that risk was 80% higher.
“This is one piece of evidence that can be considered for building new prediction models. We want women and their doctors not to assume that recently having a child is always protective for breast cancer,” Hazel Nichols said, who is a member of the Lineberger Comprehensive Cancer Center.
