Secular Europe, anal cancer and male homosexuality
From a global perspective, Europe is more secular/atheistic than the rest of the world although it does have a considerable amount of religious immigrants who have higher birth rates (see: Secular Europe and Atheist population and Global atheism).
According to the medical journal World Journal of Gastroenterology, "Anal cancers (AC) are relatively rare tumors. Their incidence is increasing, particularly among men who have sex with other men due to widespread infection by human papilloma virus."
In 2014, PharmaTimes Online reported: "Some 6,800 new cases of anal cancer are estimated to occur annually in Europe, among which about 75-80% are attributable to HPV types 16 and 18.
Cancer Research UK indicates: "There were around 1,300 new cases of anal cancer in the UK in 2014, that’s around 4 cases diagnosed every day....Since the early 1990s, anal cancer incidence rates have increased by almost three-fifths (56%) in the UK.
