A new study shows that cancer is attributable to a significant proportion of cancer cases across the United States.
It is well known that alcohol is linked to cancers, but the state-level data shows for first time the impact of different levels of alcohol consumption and its cancer effects. This is also concerning for South Africa as the country has high rates of alcohol use, consuming 5 billion litres of alcohol annually, around 9 to 10 litres of pure alcohol for each individual (and likely more if sorghum beer is counted).
From data spanning 2013 to 2016, the percentage of cancer cases that are linked to alcohol ranged from a high of 6.7% in Delaware to a low of 2.9% in Utah. Following this pattern, Delaware also had the highest proportion of alcohol-related cancer deaths (4.5%) and Utah had the lowest (1.9%).
Farhad Islami, MD, PhD, and a team at the American Cancer Society, said: “This information is important for prioritising state-level cancer prevention and control efforts to reduce alcohol consumption and the burden of alcohol-related cancers.”
Alcohol use was more tightly linked to certain cancers: the proportion of oral cavity/pharyngeal cancer cases attributable to alcohol ranged from 36% in Utah to 62.5% in Delaware and was over 45% in all but five US states.
The majority of cases and deaths from the examined cancer types were found more in men, reflecting men’s higher consumption of alcohol.
Overall, alcohol was attributable to 8% of all cancer cases and 3.2% of cancer deaths. The American Cancer Society’s guideline for Diet and Physical Activity for Cancer Prevention states that it is best to abstain from alcohol entirely, and if not to limit drinks to 2 per day for men and 1 per day for women.
