Study Confirms Added Cancer Risk for Diabetics, Especially Women
FRIDAY, July 20, 2018 (HealthDay News) -- The increased risk of cancer in people with diabetes is higher for women than men, a new study finds.
Previous research identified the link between diabetes and cancer risk, but this study looked at whether that risk differs between men and women.
The takeaway: Among people with diabetes, women have a 6 percent higher risk of cancer than men, the researchers said.
And based on the researchers' analysis of data from 47 studies, diabetics of both sexes are at greater risk of cancer than people without diabetes.
For women with type 1 or type 2 diabetes, the cancer risk is 27 percent higher compared to other women. And men with diabetes have a 19 percent higher cancer risk than men who don't have the blood sugar disease, the findings showed.
The researchers also examined specific types of cancer in people with diabetes and found that, compared to men, women have a 15 percent higher risk of leukemia, a 14 percent higher risk of stomach cancer, a 13 percent higher risk of oral cancer, and an 11 percent higher risk of kidney cancer.
But women have a 12 percent lower risk than men for liver cancer, according to the report.
"Further studies are needed to clarify the mechanisms underlying the sex differences in the diabetes-cancer association," the study authors concluded.
The report, from Toshiaki Ohkuma of the University of New South Wales in Australia and colleagues at the University of Oxford in England, was published July 19 in the journal Diabetologia.
Cancer is the second leading cause of death worldwide, accounting for 8.7 million deaths in 2015. About one in four women and one in three men will develop cancer during their lifetime, the study authors noted in a journal news release.
In addition, in 2015, there were 415 million adults worldwide with diabetes and 5 million diabetes-related deaths.
