After gathering all the data, they concluded that about 3.5 percent of all cancer-related deaths were due to alcohol consumption.
Furthermore, in 2012, they discovered approximately 5.5 percent of all new cancer occurrences and 5.8 percent of all cancer deaths worldwide were attributable to drinking alcohol.
"The importance of alcohol drinking as a contributing factor to the overall cancer burden is often underappreciated," the organization said in a statement. "Associations between alcohol drinking and cancer risk have been observed consistently regardless of the specific type of alcoholic beverages."

Some suggestions include limiting youth exposure to advertising of alcoholic beverages and increasing alcohol prices and taxes.
Scientists also hope to conduct more research.
