One in four new breast cancers and one in five colon cancers in Canada attributed to alcohol

July 14, 2021 (Toronto) A new study from the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC), published in the journal Lancet Oncology, has found an association between alcohol and a substantially higher risk of several forms of cancer, including breast, colon, and oral cancers. Increased risk was evident even among light to moderate drinkers (up to two drinks a day), who represented 1 in 7 of all new cancers in 2020 and more than 100,000 cases worldwide.

In Canada, alcohol use was linked to 7,000 new cases of cancer in 2020, including 24 per cent of breast cancer cases, 20 per cent of colon cancers, 15 per cent of rectal cancers, and 13 per cent of oral and liver cancers.

“All drinking involves risk,” said study co-author Dr. Jürgen Rehm, Senior Scientist, Institute for Mental Health Policy Research and Campbell Family Mental Health Research Institute at CAMH. “And with alcohol-related cancers, all levels of consumption are associated with some risk. For example, each standard sized glass of wine per day is associated with a 6 per cent higher risk for developing female breast cancer.”

“Alcohol consumption causes a substantial burden of cancer globally,” said Dr. Isabelle Soerjomataram, Deputy Branch Head, Cancer Surveillance Branch at IARC. “Yet the impact on cancers is often unknown or overlooked, highlighting the need for implementation of effective policy and interventions to increase public awareness of the link between alcohol use and cancer risk, and decrease overall alcohol consumption to prevent the burden of alcohol-attributable cancers.”

Dr. Leslie Buckley, CAMH Chief of Addictions, added: “In our clinic we are seeing many people who report increased alcohol use since the onset of the pandemic. Although this may be related to temporary stressors, there is a potential for new habits to become more permanent. The consequences with alcohol use are often subtle harms initially that take time to show themselves, while long-term consequences such as cancer, liver disease and substance use disorder can be devastating.”

The modelling study was based on data on alcohol exposure from almost all countries of the world, both surveys and sales figures, which were combined with the latest relative risk estimates for cancer based on level of consumption.

“Alcohol causes cancer in numerous ways,” explained Dr. Kevin Shield, Independent Scientist, Institute for Mental Health Policy Research, and study co-author. “The main mechanism of how alcohol causes cancer is through impairing DNA repair. Additional pathways include chronic alcohol consumption resulting in liver cirrhosis, and alcohol leading to a dysregulation of sex hormones, leading to breast cancer. Alcohol also increases the risk of head and neck cancer for smokers as it increases the absorption of carcinogens from tobacco.”

Dr. Rehm says research into the link between light to moderate drinking and cancer is relatively new and that public policy does not yet reflect the degree of cancer risk. He added, “As an epidemiologist, I would recommend higher taxes to fully reflect the burden of disease from alcohol. Along with limiting the physical availability and marketing of alcohol, price controls are recognized as high-impact, cost-effective measures to reduce alcohol-related harm.” Governments can also consider requiring manufacturers to include information about health and safety risks associated with alcohol consumption, including cancer risk, on alcoholic beverage labels.

These suggestions and many others can be found in CAMH’s Alcohol Policy Framework. Updated in September 2019, the document proposes evidence-informed measures to effectively address the health and social harms associated with alcohol.
