Drinking Increases a Young Woman's Cancer Risk
Women who drink alcohol before their first pregnancy could be increasing their risk of benign breast disease and breast cancer.
Researchers at the Washington University School of Medicine in St. Louis looked at the medical records of more than 90,000 women.
They found about 2,500 of them who drank alcohol before getting pregnant, developed breast tumors.
Researchers say breast tissue is very susceptible to carcinogens after a woman's first period and before her first pregnancy.
