Yoghurt risky for ovarian cancer?

Q:While reading the special report on alternatives to hysterectomy (vol 7 no 1), I came cross the paragraph that says that women should eliminate dairy products, especially yoghurt and cottage cheese, in order to avoid ovarian cancer. Galactose is

In order for lactose to be digested, it must be split into glucose and galactose by the enzyme lactase secreted by the small intestine.

Are there any other articles, findings or studies verifying this theory? Catherina Sarri, Athens, Greece........
