A popular breast cancer drug may increase the risk of heart problems.

Researchers say the drug Herceptin can increase heart problems in elderly patients, especially those with a history of heart disease or diabetes.

According to the new study, 12 percent of women ages 70 to 92 taking Herceptin developed heart problems and 33 percent of women with diabetes developed heart problems.

The results of the study compared with six percent of diabetes-free women.
