Sydney: Women suffering from diabetes may be at a higher risk of developing cancer than men, a new study has found.

The findings suggested that among the study participants, women with diabetes (Type 1 and Type 2) were at higher risks for developing kidney cancer (11 per cent), oral cancer (13 per cent), stomach cancer (14 per cent) and leukaemia (15 per cent) compared to men with the similar condition.

Diabetes affects more than 415 million people worldwide, with five million deaths every year.

According to the researchers, it is believed that heightened blood glucose may have cancer-causing effects by leading to DNA damage.

"The link between diabetes and the risk of developing cancer is now firmly established," said lead author Toshiaki Ohkuma from The George Institute for Global Health in Australia.

"The number of people with diabetes has doubled globally in the last 30 years but we still have much to learn about the condition," Ohkuma added.

For the study, published in the journal Diabetologia, the researchers examined data on all-site cancer events (incident or fatal only) from 121 cohorts that included 19,239,302 individuals.

The researchers found that women with diabetes were 27 per cent more likely to develop cancer than women without diabetes but for men the risk was 19 per cent higher.

They also found that diabetes was a risk factor for the majority of cancers of specific parts of the body for both men and women.

Overall, it was calculated that women with diabetes were six per cent more likely to develop any form of cancer than men with diabetes.

"It's vital that we undertake more research into discovering what is driving this, and for both people with diabetes and the medical community to be aware of the heightened cancer risk for women and men with diabetes," Ohkuma noted.
