Researchers found that men who drank 430 grams, or 1 3/4 cup of milk, per day had a 25% increased risk of developing prostate cancer compared to me who only drank 20.2 grams of milk per day.

Older Icelandic men who remember chugging a lot of milk in their teens are three times as likely to be diagnosed with advanced prostate cancer as more-moderate milk drinkers, researchers have found.

Purpose To establish whether the association between milk intake and prostate cancer operates via the insulinlike growth factor (IGF) pathway (including IGF-I, IGF-II, IGFBP-1, IGFBP-2, and IGFBP-3).

Similar to the first study's findings, skim milk was linked with advanced prostate cancer. Calcium from non-dairy food, by contrast, was tied to a reduced risk of non-advanced prostate cancer.
