• Overall, around a fifth (20%) of the participants consumed dairy products regularly (primarily milk), 11% consumed dairy products monthly, and 69% were non-consumers. The average consumption was 38g per day overall in the whole study population and 81g per day among regular dairy consumers (compared with an average consumption of around 300g per day in participants from the UK Biobank).
• During the study period 29,277 new cancer cases were recorded, with the highest rate being for lung cancer (6,282 cases), followed by female breast (2,582 cases), stomach (3,577 cases), colorectal (3,350 cases) and liver cancer (3,191 cases).
• People who consumed dairy products regularly had significantly greater risks of developing liver and breast cancer. For each 50g/day intake, the risk increased by 12% and 17% respectively.
• Regular dairy consumption was associated with an increased risk of lymphoma (though this was not statistically significant).
• There was no association between dairy intake and colorectal cancer, prostate cancer, or any other type of cancer investigated.***
Both liver and breast cancer are among the most common types of cancer in China, accounting for around 393,000 and 368,000 new cancer cases each year respectively.**** While these study results do not prove causation, there are several plausible biological mechanisms that may explain these associations, according to the researchers. Greater dairy consumption, for instance, may increase levels of insulin-like growth factor-I (IGF-I), which promotes cell proliferation and has been associated with higher risks for several types of cancer. Potentially, female sex hormones present in cow’s milk (such as oestrogen and progesterone) may have a role in the increased risk of breast cancer, whilst saturated and trans-fatty acids from dairy products may increase the risk of liver cancer. For the majority of Chinese people who do not produce enough lactase, dairy products may also be broken down into products that affect cancer risk.

Of course the severity not as high as liquor but better don't take milk or other dairy products as your main source of daily protein. Take eggs or chicken breasts as your main source instead
