The number of rectal cancers, tongue and tonsils increased. This is the conclusion of researchers at the University of Calgary in Alberta (Canada).
The Canadian study was based on the Alberta Cancer Registry between 1975 and 2009. Scientists analyzed data on cancers caused by HPV, a virus that can, in its most severe form, cause many health problems, such as genital warts and cancer.
A worrying increase
The research team first noted that the number of Cervical cancer had decreased by 1.1 points. In contrast, the rates of oral cavity cancer more than doubled in men, from 1.2 to 3.7 per 100,000 men. A smaller increase in women, from 0.6 to 1.
Number of rectal cancers meanwhile has seen a sharp increase among men, from 1.8 to 3.8, as well as among women (rate from 0.7 to 1.5 per 100,000).
These conclusions do not reassure the main author of the study, Lorraine Shack who highlights the importance of systematic screening: “the increase in the rate of cancers of the oral cavity in young men, and the rate of rectal cancer in young women is worrisome, because there is no systematic screening for these diseases “.
