Breast cancer survivors face higher risk of diabetes, high blood pressure

In a new study from Kaiser Permanente, researchers found women with a history of breast cancer have a higher incidence of high blood pressure and diabetes up to 10 years following diagnosis.

They examined 14,942 women with invasive breast cancer (diagnosed from 2005 to 2013) and same number of noncancer people.

The researchers found that breast cancer survivors had higher cumulative incidence rates of high blood pressure (10.9% versus 8.9%) and diabetes (2.1% versus 1.7%) after two years compared with controls, with higher diabetes incidence persisting after 10 years (9.3% versus 8.8%).

They also found breast cancer survivors had a higher risk for diabetes versus controls.

Diabetes risk continued to be higher among patients treated with chemotherapy, left-sided radiation, or endocrine therapy.

For cases receiving left-sided radiation or endocrine therapy, high blood pressure risk was higher.

Higher risk was seen for cases with normal weight (body mass index, <24.9 kg/m2) both overall and within treatment subgroups versus controls.

These findings highlight patients with breast cancer as a vulnerable population at higher risk of heart risk factors and support targeted heart disease surveillance.

If you care about breast cancer risk, please read studies about a major cause of deadly breast cancer, and healthy diet that could protect women from breast cancer.

For more information about health, please see recent studies about common diabetes drug that could help reverse liver inflammation, and results showing these two drugs are most effective in lowering blood sugar in type 2 diabetes.

The study is published in the Journal of Clinical Oncology. One author of the study is Marilyn L. Kwan, Ph.D.
