Health Update: Y chromosome linked to cancer and death risk in men

The male Y chromosome may have a role in prolonging men's lives and fighting cancer, scientists have said. Research into 1,153 elderly men at the University of Sweden found those who had lost part of their Y chromosome died on average 5.5 years earlier than those who had not. Women live on average 7.5 years longer than men in Europe and the reasons behind this are not fully known. Cancer Research said the study was "intriguing". Scientists assessed how many blood cells had age-related loss of the Y chromosome (LOY) through blood test in the men, aged between 70 and 84. Tumour prevention Men with a "significant amount" of loss died earlier, said researchers. LOY was associated with general risk of death in 637 out of the group of men and risk of death due to non-blood related cancer in 132 of the cases. While a man's risk of cancer does increase with age, there are things all men can do to stack the odds in their favour” Dr Julie S...
