Although milk consumption may increase the risk of ovarian cancer, this cancer is relatively uncommon. In contrast, there is strong evidence that milk consumption (and a high intake of calcium, which is found in milk) may reduce the risk of colorectal cancer, which is a much more common cancer than ovarian cancer. Consumption of low-fat milk might also lower the risk for other diseases, such as type 2 diabetes and cardiovascular disease.

This gives some evidence that milk might be linked to increase risk of ovarian cancer, but more research is needed.

We don't know how much milk is too much for women with genetic predisposition.

We find a strong inverse association. Those who drank two or more cups of tea day, had almost a halt in the risk of ovarian cancer compared to those who never drank tea.
