Uppsala University researchers led by Lars Forsberg finally figured out why women live longer than men. A recent study by Swedish geneticists has shown that there is a clear link between the loss of the Y chromosome in blood cells, a short lifespan, and an increased risk of death from internal cancer..

As you know, according to statistics, men live less than women.. In addition, they are more susceptible to the development of oncological diseases and they have the highest mortality from oncology.. The fact is that with age, normal cells experience changes in DNA, associated primarily with serious diseases, such as diabetes and cancer, according to Pannochka, an Internet publication for girls and women from 14 to 35 years old.. net In Nature Genetics, genetics have published the results of a study of blood samples of more than 1,000. 600 older men. The most common genetic change, it turned out, was the loss of a Y chromosome in white blood cells..

Scientists note that the study participants were observed over the years.. Experts managed to find a clear connection between a decrease in life expectancy and the loss of the Y chromosome.

It should be recalled that only males have the Y chromosome.. Genes that are contained in the chromosome determine sex, are involved in the production of semen, and they also contain a certain amount of hereditary information. Y-chromosomes play a major role in the fight against cancer and explain, in addition, they explain why men, unlike women, are more likely to get cancer.

Geneticists are confident that in the future, the analysis of men for the Y chromosome will become a useful marker in determining the risk of cancer.
