ScienceDaily (Apr. 25, 2008) — Depending on which variant of a certain gene a woman has, a coffee consumption rate of at least two-three cups a day can either reduce the total risk of developing breast cancer or delay the onset of cancer. This is shown in new research from Lund University and Malmö University in Sweden.
