​Women who are habitual consumers of large servings of dairy products may have a high tendency of developing ovarian cancer.

This study investigated the association between the consumption of dairy products and lactose and the likelihood of developing ovarian cancer. A team of Swedish scientists collated and analyzed data on the ovarian cancer hazard ratios and dairy product consumption rates of 61,084 women between the ages of 38-76 years recruited from the Swedish Mammography Cohort.

Researchers observed that subjects who regularly consumed 4 servings or more of dairy products per day had two times higher risk of developing serous ovarian cancer (Serous Carcinoma) than women who consumed less than 2 servings of dairy products per day, with milk having the strongest ovarian cancer-promoting effect. In contrast, no association was found between dairy product intake and other types of ovarian cancer in this study. The findings of this study indicate that regular intake of dairy products may increase a woman's susceptibility to ovarian cancer.
