Vitamin D does not protect men from getting prostate cancer, but it may lessen their chances of dying of it.
In a new study, men with the highest levels of vitamin D in their blood were 57 percent less likely than men with the lowest levels to succumb to prostate cancer.
However, no link was found between vitamin D levels and having prostate cancer, the researchers said.
"Prostate cancer is a very heterogeneous disease," said study researcher Irene Shui, an epidemiologist at the Harvard School of Public Health. Some tumors progress quickly, spreading to other sites in the body and causing death, while others stay within the prostate for years and never affect a man's health or life.
