Who is Dr Miller. Does he present his research in medical journals, or just on YouTube? Got a link to a research paper? "Look it up on YouTube" isn't a valid response when someone asks for proof of something...

China's a big place. Lots of studies going on, I'd imagine. Again - got a link to a research paper?
How about this: https://www.cancerresearchuk.org/about-cancer/causes-of-canc...
"Milk and dairy are good sources of calcium and protein which are needed as part of a healthy, balanced diet. Calcium is important for teeth and bone health.
Studies looking into the link between cancer and dairy products have not given clear results. There is evidence that dairy products could reduce the risk of bowel cancer, but we cannot say for sure that this is the case. There is no strong evidence linking dairy products to any other types of cancer. We need further research to find out more about the links between dairy products and cancer risk."
