Cancer Risk Increased Before, After Diabetes Diagnosis

Cancer Network


....Patients diagnosed with diabetes were significantly more likely to have been diagnosed with cancer within the 10 years prior to the diabetes diagnosis compared with individuals without diabetes (hazard ratio [HR], 1.23 [95% CI, 1.19–1.27]). In addition, the incidence of prior cancer was higher for patients with diabetes at each individual cancer site studied except for ovarian and cervical cancer.
“This finding is consistent with other studies that have shown a significantly higher rate of breast cancer and colon cancer before a diagnosis of diabetes,” the researchers wrote. “This observation may be due to shared metabolic risk factors for diabetes and cancer that are present during the prediabetes period, such as insulin resistance and hyperinsulinemia.”
