BOSTON (January 8, 2013)--A lawyer for four sisters who believe their breast cancer was caused by a drug their mother took during pregnancy says the drug’s maker failed to test its effect on fetuses before promoting it as a way to prevent miscarriages.
The sisters are suing Eli Lilly and Co., alleging the company urged doctors to prescribe the synthetic estrogen known as DES without proof that it prevented miscarriages and other reproductive problems.
A lawyer for Eli Lilly told a jury Tuesday that there is no evidence that DES causes breast cancer in the daughters of women who took it.
He also said no medical records show the mother of the women took DES, or that if she did take it, that Eli Lilly made it.
Many companies produced the drug.
