most guys crayfish more common in men than women, for reasons that are not yet fully understood, according to a new US study. Scientific research.

The answer probably lies more in underlying biological differences between the sexes and less in differences in male and female behaviors such as smoking, drinking, diet and other lifestyle factors. We hope that a better understanding of the causes of these differences in cancer risk will lead to better cancer prevention and treatment.

Researchers led by Dr. Sarah Jackson of the US National Cancer Institute, who published a related publication in the American Cancer Society’s CANCER journal, analyzed data on 171,274 men and 122,826 women aged 50 to 71. During the study, 17,951 new cancers were diagnosed in men and 8,742 in women.

The likelihood of cancer was lower in men than in women, only for thyroid and gallbladder cancers. For cancers elsewhere in the body, the risk was 1.3 to 10.8 times higher in men than in women.

The most elevated risk in men is cancer of the esophagus (10.8 times higher compared to women), larynx (3.5 times higher) and bladder (3.3 times higher).

The study estimates that men have an increased risk of developing most types of cancer, even taking into account their wide range of riskier behaviors and more frequent exposure to environmental carcinogens. It is estimated that gender differences in behavior only partially explain (from 11% in esophageal cancer to 50% in lung cancer) the increased risk of cancer in men.

Therefore, according to researchers, it is the biological differences (genetic, immunological, etc.) between the two sexes that play the main role in the fact that men are more vulnerable to cancer than women.

“Our results show that there are differences in cancer incidence that are not explained by environmental factors alone. This means that there are inherent biological differences between men and women that affect cancer predisposition,” said Dr. Jackson.
