St. Petersburg, FL -- A drug breast cancer survivors are widely prescribed may increase your odds of having heart problems.
Researchers at Seattle's Group Health Research Institute found the drug trastuzumab, sold as Herceptin, increases the risk for developing heart failure more than chemotherapy alone, and the risks are even higher when the two were combined.
They looked at the health of more than 12,000 women diagnosed with breast cancer to determine the heart risks were greater than previously thought.
