Alcohol and smoking are key causes for bowel cancer 


A new global study has found that lifestyle risk factors such as alcohol consumption and cigarette smoking

are important risk factors for bowel cancer. Researchers have shown that people who consume the largest

quantities of alcohol (equivalent to > 7 drinks per week) have 60% greater risk of developing the cancer,

compared with non-drinkers. 


Smoking, obesity and diabetes were also associated with a 20% greater risk of developing bowel cancer -

the same risk linked with consuming high intakes of red and processed meat.


Approximately one million new cases of bowel (colorectal) cancer are diagnosed worldwide each year, and

more than half a million people die from this type of cancer. In Australia alone, it is the most commonly

occurring cancer with more than 12,000 new cases diagnosed each year.


According to lead researcher Associate Professor Rachel Huxley at The George Institute, the most startling

finding of this study was, “The strong, and largely, unknown association between high intakes of alcoholic

beverages with risk of colorectal cancer.  Most people probably know that being overweight and having poor

dietary habits are risk factors for the disease, but most are probably unaware that other lifestyle risk factors

such as alcohol consumption, cigarette smoking and diabetes are also important culprits.”  


Australia’s National Health and Medical Research Council recommend individuals shouldn't be drinking

more than two standard drinks per day.


On a positive note, researchers also demonstrated that physical activity lowered an individual’s risk of the

disease but surprisingly, there was little evidence to indicate that high intakes of fruit and vegetables were

protective against bowel cancer.  


“These findings strongly suggest that a large proportion of colorectal cancer cases could potentially be

avoided by making relatively modest lifestyle adjustments such as drinking less, quitting smoking, eating

healthily and being a little more active”, said Associate Professor Huxley.  “Such changes would also have

huge benefits in terms of reducing an individuals’ risk of developing other major forms of illness including

cardiovascular disease.”

The study reviewed more than 100 published studies that had reported on the association between major

and modifiable risk factors for colorectal cancer including alcohol, smoking, diabetes, physical activity and

various dietary components.
