Study shows women born to older women have increased risk of breast cancer
Feb 6, 2012
A new study conducted by researchers at the Carlos III Health Institute (ISCIII) found that women who were born to mothers aged 39 and older along with women who were taller and thinner than the average girl prior to puberty have a higher breast density. With this comes a higher risk of developing breast cancer.
Researchers studied 3,574 women between the ages of 45 and 68 to come up with their findings.
Virginia Lope, lead author of the study and researcher at the National Center for Epidemiology at the ISCIII, explains "accumulated exposure to hormones along with growth factors in the earlier stages of life when the breasts begin to develop both condition breast tissue composition and influence the probability of developing a tumor as an adult."
According to the American Cancer Society, one in eight women in the U.S. will be diagnosed with breast cancer at some point during her lifetime. Not only is it the second most common form of cancer behind skin cancer, but it is the second leading cause of cancer-related death among women, following only lung cancer.
