LONDON — Consuming red meat may increase the risk of colon cancer in women, a new research in Britain has found.
Researchers studied whether beef is associated with risk of colon and rectal cancer compared with poultry, fish or vegetarian diets, according to a research conducted by the University of Leeds, a diet free from red meat significantly reduces the risk of a type of colon cancer in women living in the United Kingdom.
If a woman avoids eating red meat, her risk of colon cancer is significantly reduced, the findings were published Sunday in the International Journal for Cancer said.
When comparing the effects of these diets to cancer development in specific subsites of the colon, they found that those regularly eating red meat compared to a red meat-free diet had higher rates of distal colon cancer – cancer found on the descending section of the colon, where faeces is stored.
Previous studies have suggested that eating lots of red and processed meat increases risk for colorectal cancer but the researchers said there is limited available information about specific dietary patterns and where cancer occurred in the bowel.
Researchers found that regular eaters of red meat had higher rates of distal colon cancer compared with others. The cancer was found on the descending section of the colon, where feces is stored.
Lead author Dr Diego Rada Fernandez de Jauregui said, “The impact of different types of red meat and dietary patterns on cancer locations is one of the biggest challenges in the study of diet and colorectal cancer”.
“Our research is one of the few studies looking at this relationship and while further analysis in a larger study is needed, it could provide valuable information for those with family history of colorectal cancer and those working on prevention.”
The study analysis explored the relationship between the four dietary patterns and colorectal cancer and a further exploratory analysis examined the correlation between diet and colon subsites.
Co-author Janet said, “Our study not only helps shed light on how meat consumption may affect the sections of the colorectum differently, it emphasises the importance of reliable dietary reporting from large groups of people”.

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.
