SYDNEY — The increased risk of cancer in people with diabetes is higher for women than men, according to a major study by Australian researchers.
Women with diabetes were also at greater risk than men of getting leukemia and stomach, mouth and kidney cancers, the George Institute for Global Health medical research group said in a statement on Friday.
Previous research identified the link between diabetes and cancer risk, but this study looked at whether that risk differs between men and women.
Among people with diabetes, women have a 6 percent higher risk of cancer than men, the researchers said in the study, published in the journal Diabetologia.
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.
And, for men the risk was 19 percent higher. The numbers “highlight the need for more research into the role diabetes plays in developing cancer” and “demonstrate the increasing importance of sex specific research,” said the researchers.
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.
“Further studies are needed to clarify the mechanisms underlying the sex differences in the diabetes-cancer association,” the study authors concluded.
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.
Similary, diabetes affects more than 415 million people worldwide, with 5 million deaths linked to it every year.

Suicide can’t be predicted by asking about suicidal thoughts : Study
Most people who died of suicide deny they experience suicidal thoughts when asked by doctors in the weeks and months leading up to their death, a major Australian study has found.
The findings, co-authored by clinical psychiatrist and Professor Matthew Large from UNSW’s School of Psychiatry, Sydney that published in the journal BJPsych Open The meta-analysis challenge the widely-held assumption that psychiatrists can predict who will suicide by asking if they are preoccupied with thoughts of killing themselves.
The study showed that 80% of patients who were not undergoing psychiatric treatment and who died of suicide reported not to have suicidal thoughts when asked by their psychiatrist or GP.
“If you meet someone who has suicidal ideation there is a 98 per cent chance that they are not going to suicide,” said Professor Large, an international expert on suicide risk assessment who also works in the emergency department of a major Sydney hospital.
“But what we didn’t know was how frequently people who go on to suicide have denied having suicidal thoughts when asked directly,” he added.
“This study proves we can no longer ration psychiatric care based on the presence of suicidal thoughts alone. We need to provide high-quality, patient-centred care for everyone experiencing mental illness, whether or not they reveal they are experiencing suicidal thoughts,” Professor Large said.
About one in 10 people will have suicidal ideation in their lifetime. But the study showed suicidal ideation alone was not rational grounds for deciding who gets treatment and who does not, Professor Large said.
“We know that suicide feeling is pretty common and that suicide is actually a rare event, even among people with severe mental illness,” Professor Large added.
Suicidal ideation tells us an awful lot about how a person is feeling, their psychological distress, sometimes their diagnosis and their need for treatment but it’s not a meaningful test of future behaviour.
Suicidal feelings can fluctuate rapidly and people may suicide very impulsively after only a short period of suicidal thoughts.
But, people had good reasons not to disclose thoughts of suicide, fearing stigma, triggering over-reactions or upsetting family and friends, and being involuntarily admitted for psychiatric treatment, Professor Large said.
Professor Large emphasized that clinicians should not assume that patients experiencing mental distress without reporting suicidal ideas were not at elevated risk of suicide.
