A new study shows older women who take a certain medicine for high blood pressure may be more likely to develop breast cancer. Researchers at Fred Hutchinson Cancer Research Center found long-term use of calcium channel blockers significantly raised the risk of the disease. Millions of Americans take the drugs. Doctors say more study is needed to confirm the findings and patients should not stop taking the prescriptions.

British researchers say people who walk to work are 40 percent less likely to have diabetes than those who drive. The new study also found people who cycle or use public transportation to commute are healthier than drivers, too. Physicians say the study highlights the importance of getting exercise on a regular basis.

And which mothers choose to breastfeed may depend on their personality. Research in the Journal of Advanced Nursing found women who are outgoing are more likely to breastfeed and stick with it. But mothers who are anxious or introverted tend to use formula instead. Doctors say anxious women may feel more self conscious about breastfeeding.
