When people with Type 2 diabetes are diagnosed with cancer – a disease for which they are at higher risk – they ignore their diabetes care to focus on cancer treatment, according to new Northwestern Medicine® research. But uncontrolled high blood sugar is more likely to kill them and impair their immune system’s ability to fight cancer.
However, people with Type 2 diabetes who received diabetes education after a cancer diagnosis were more likely to take care of their blood sugar. As a result, they had fewer visits to the emergency room, fewer hospital admissions, lower health care costs, and they tested their blood sugar levels more often than people who didn’t have the education. They also had more hemoglobin a-1c level tests at their doctor’s offices. The latter is a critical marker of how well someone has managed their diabetes and blood sugar over the last three months.
“People with diabetes hear cancer and they think that it is a death sentence, so who cares about diabetes at this point?” said June McKoy, MD, director of geriatric oncology at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. “But if they’re not careful, it’s the diabetes that will take them out of this world, not the cancer. That’s why this education is so critical when cancer comes on board. Patients must take care of both illnesses.”
McKoy is the senior author of the study recently published in the journal Population Health Management. Lauren Irizarry, a fourth-year medical student at Feinberg, is the lead author.
Uncontrolled high blood sugar can result in kidney damage and failure as well as blindness and amputation of the feet as blood vessels are damaged by excess sugar. In addition, Type 2 diabetes dampens the immune system and hampers the body’s ability to fight cancer. People with diabetes have a higher incidence of liver cancer, pancreatic cancer, colon cancer, breast cancer, bladder cancer, and endometrial cancer.
