Y chromosome linked to cancer and death risk in men

Swedish researchers have found that the male Y chromosome has a potential role in preventing tumors and death risk in men.

The study shows that the men who lose the Y chromosome in their blood cells due to an age-related phenomenon have a higher risk of cancer and may have shorter life spans.

Researchers say that the findings may explore why the rates of certain cancers are higher in men than women. Study also unveiled that the men who had a significant Y chromosome loss appeared to have a much higher risk of dying from cancer. Researchers believe that Y chromosome genes may enable blood cells to help immuno-surveillance, where the immune system detects and kills tumor cells.
