For women under 50, drinking more than a cup of milk daily can help lower the risk of breast cancer.

The team of Seoul National University Preventive Medicine (Kang Dae-hee, Shin Woo-kyung, Lee Hwi-won, Shin Ae-sun, and Jong-gu Lee) received 9,306 big data (HEXA study) among 40-69 year old women who received health examinations from 38 general hospitals from 2004 to 2013. Cohort study found that the link between milk intake and breast cancer was observed.

The research paper is published in the latest issue of Nutrients, an international journal.

The research team tracked the incidence of breast cancer in the survey over an average of 6.3 years in conjunction with national cancer registry data.

In the process, all female and socio-demographic variables, including fertility, first birth and menarche age, which affect breast cancer, were corrected.

As a result, women under 50 years of age who consumed more than 1 cup (200 ml) of milk per day (6,621) had a higher risk of breast cancer than those who consumed less than 1 cup per week (12,464). It was 42% lower.

Not daily, but under the age of 50 (5,792 people) who drink milk 2 to 6 days a week, the risk of breast cancer was estimated to be 13% lower.

Especially in their 40s, the researchers found that the more milk they drink per day, the lower the risk of developing breast cancer.

In women over 50, milk was shown to prevent breast cancer at 10%, under the same comparison conditions.

In this study, however, dairy products other than milk (such as yogurt and cheese) were not associated with reducing the risk of breast cancer.

Professor Kang Dae-hee, research director, said, "Calcium in milk has anti-proliferative properties in breast cancer cells, which protects against breast cancer. Vitamin D increases cell differentiation and sandpaper death, which lowers the risk of breast cancer." On the preventive side, it can be helpful to drink more than a cup of milk every day since you are young. ”
