(ANSA) – ROME, AUGUST 09 – Men get cancer more than women and the reason could lie not simply in lifestyles, such as smoking, diet, alcohol consumption or, in exposure to occupational hazards, but in gender-related biological differences. This is what an American study conducted by the National Cancer Institute and published in Cancer, the journal of the American Cancer Society suggests.
To reach this result, the team of researchers analyzed data collected between 1995 and 2011 from 171,274 males and 122,826 females aged between 50 and 71 years.
During that time, 17,951 new cancers were diagnosed in men versus 8,742 in women. In men the incidence was lower than in women only for thyroid and gallbladder cancers, while for all other cancers the risk was 1.3 to 10.8 times higher. The greatest differences between men and women were observed for cancer of the esophagus (with a 10.8 times higher risk for men), larynx (3.5 times higher), esophagus-stomach passage or cancer. cardia (3.5 times higher) and bladder (3.3 times higher).
The study found that differences in risk behaviors and carcinogen exposures between the sexes accounted for only a modest percentage of the greater male risk.
“Our results show that there are differences in cancer incidence that are not explained by environmental exposures alone. This suggests that there are inherent biological differences between men and women that influence cancer susceptibility,” said Sarah S. Jackson. first signatory of the study. (HANDLE).
