Dairy intake lowers chances of survival from prostate cancer, according to a study published in the International Journal of Cancer. Researchers followed 525 men with recent prostate cancer diagnoses and tracked dairy product consumption and mortality rates. Those who consumed three or more servings of high-fat dairy a day, including butter, increased their risk of death from cancer when compared to those who consumed less dairy. IGF-1 and other hormones specific to dairy may be the mechanisms behind the increased risk. These findings support previous research on dairy consumption and prostate cancer risk.
