Alcohol and cancer

The #1 health-related fear for most people is cancer. The #1 health-related fear for NZ women is breast cancer. Few people realise alcohol directly causes cancer and is one of the most potent cancer causers we have in modern society. Alcohol has been classified by WHO as a class 1 Carcinogen, meaning it is a cancer causer in the same company as asbestos, mustard gas, formaldehyde and plutonium-239. The biggest damage caused by alcohol is cancer; breast cancer, liver cancer, bowel cancer, mouth cancer and many others. The challenge we have is that nobody talks about ‘alcohol and cancer’ the way we do about ‘cigarettes and cancer’ because alcohol is so deeply soaked into society. Talking about alcohol as a problem makes many of us very uncomfortable.

“The more you drink, the higher your risk of cancer. The less you drink, the less at risk you are of developing cancer. It is as simple as that”

Naomi Allen, Cancer Epidemiologist, Oxford University, UK.

Alcohol is a class 1 carcinogen

According to the international, highly respected, European Prospective Investigation into Cancer (EPIC) study:

  • Over 13% of the incidence of total global cancer was attributable to former and current alcohol consumption1
  • One drink daily raises your oesophageal cancer risk by 30%, your mouth cancer and pharynx cancer risk by 17%, and your breast cancer risk by 5%2
  • On daily drink causes 34,000 preventable deaths a year worldwide2
  • Moderate drinkers were 60% more likely to develop mental health problems than non-drinkers3
  • Two drinks per day raises your colon cancer risk by 60% over non-drinkers4
  • Two glasses of alcohol a day triples your mouth cancer risk5
  • Men consuming three drinks a day raise their risk for gastric cancer risk more than 700%6
  • Men consuming three drinks a day raise their risk of pancreatic cancer by 60%7
  • Postmenopausal women drinking alcohol twice daily double their risk of developing endometrial cancer8

Alcohol = cancer, even at the lowest levels

A huge multicountry study announced its findings late 2013 in regards to the lifestyle cause of cancer worldwide. These latest cancer incidence rates were assembled by the International Agency for Research on Cancer on behalf of WHO. They confirmed that alcoholic intake was linked to cancer even at the lowest intake. ‘Consumption of alcoholic beverages is associated to cancer of the female breast, even at low levels of alcohol consumption. Experimental and epidemiologic studies show that alcohol-induced breast cancer may be stronger for exposure during adolescence and early adulthood.’9

“If you have cancer in your family history and you want to reduce your cancer risk as far as possible, then do not drink. There is no evidence of a safe alcohol dose below which cancer-causing effects do not occur. Alcohol creates cancer through direct DNA damage, increased oestrogen levels, liver damage, excessive weight gain and feeding cancer cells via the high sugar levels. By reducing your alcohol intake or by choosing not to consume alcohol you can reduce your bowel cancer risks significantly”
