Loss of Y chromosome can explain shorter life expectancy, higher cancer risk for men
It is a common known fact that women tend to outlive men. In a study led by researchers from Uppsala University, it showed a connection between a loss of the Y chromosome in blood cells and both a shorter life span and higher mortality from cancer in other organs. This means that men have a shorter life span than women and cancer is more frequent and deadlier in men than in women. "...Our results indicate that the Y chromosome has a role in tumour suppression and they might explain why the men get cancer more often than women..." says Jan Dumanski, professor at the Department of immunology, Genetics and Pathology, Uppsala.
I believe this type of research could prove useful in predicting the risks of developing cancer in men and hopefully being able to treat it earlier, before any major damage has been done.

This is exciting research, and it will be very interesting to see where it leads. Although I don't know what practically use this specific information has besides allowing men to be better prepared, I do hope it will lead scientists to investigate this aspect of cancer in more detail. It will give us a fuller and more complete picture of this disease which is always a good thing.
