"We believe that our data is solid and provides important evidence that adolescence is a sensitive period for the development of prostate cancer," said Johanna Torfadottir, nutrition scientists and graduate students at the University of Iceland.
Two studies on the relationship between prostate cancer and intake of milk in adolescents resulted in two different conclusions. One study concluded that milk lovers found somewhat protected from this disease, while other studies found no relationship at all.
But the two studies were considered minor and do not differentiate between tumors and tumors that have been chronic in its early stages. Research conducted Torfadottir offers a perfect natural experiment which he said as written in the American Journal of Epidemiology.
In this study, using data Torfadottir more than 2,200 men born between the years of 1907 to 1937. These people have been part of medical research that began in 1960 and in the early 2000s. Respondents were asked to answer questions about the food in the early and mid-life as part of other studies.
Among the 463 people who remember ever drank milk less than once a day in his teens, 1 percent of whom had prostate cancer or died of disease after 25 years of follow-up. Among men who claimed to drink milk once a day as a teenager, a higher percentage of 3 percent.
As reported by FoxNews on Monday (1/2/2012), Torfadottir said there are physiological mechanisms that might explain this relationship, but this is still a conjecture. He suspects this is related to eating habits. However, he did not consider milk as a cause of prostate cancer and people do not have to worry about drinking milk.
"Too early to say that drinking milk causes prostate cancer. Maybe there was a relationship, but not be considered as a cause and effect. There are many health benefits of drinking milk in adolescence," said Dr. Matthew Cooperberg, urologist at the University of California, San Francisco .
