A study of almost 10,000 Swedish, male construction workers published in the "International Journal of Cancer" in 2008 found a statistically significant increase in the incidence of the combined category of oral and pharyngeal cancer among daily users of snus. Another study reports 16 cases of oral cancer among snus users. Other studies and opinion pieces in renowned journals, such as the "British Medical Journal" and "The Lancet", do not confirm any correlation between snus usage and oral cancer, but one study suggests a probable increased risk of pancreatic cancer as a result of snus use. A pooled analysis of nine prospective studies involving more than 400,000 men and published in the "International Journal of Cancer" in 2017 found that use of snus was not associated with a greater risk for pancreatic cancer.
