The scientists revealed that heavier drinkers needed to produce greater physical output to offset other deadly diseases associated with drink. Meanwhile, people who recently gave up alcohol could also reduce their chances of getting sick if they exercised more too.
Researchers from the University of Sydney used data from participants aged 30 years and over in ten British population-based health surveys. They then compared this with death rates of alcohol-related cancers which included oral cavity, throat, larynx, oesophagus, liver, colorectal, stomach and additionally pancreas and lung
Using models, they discovered a strong direct association between alcohol consumption and mortality risk of alcohol-related cancers, with a significantly higher risk among ex-drinkers.
They discovered people who drank excessive amounts of alcohol every week (more than 14 units for women and 21 for men) but who did at least seven hours of exercise were less likely to die from these cancers.
The study published in the International Study of Cancer last week added: “Engaging in a recommended level of physical activity attenuated the negative effects of alcohol consumption on alcohol-related cancer mortality.
“This provides valuable evidence of the potential of promoting physical activity as an adjunct risk minimisation measure for alcohol-related cancer prevention.”
It is the first time analysts have looked at the link between exercise and surviving cancers linked with alcohol. Anne McTiernan, a cancer prevention expert at the Fred Hutchinson Cancer Research Centre, said that the evidence between exercise and alcohol “was clear”.
