Dairy and prostate cancer: Conflicting information

Hi! I am 73 and have 6 prostate cancer that is being watched. I drink a lot of milk and eat a lot of cheese I have read some studies that say whole milk was associated with prostate cancer and to drink fat free milk. Then I read another study saying that skim milk was associated with prostate cancer, but high fat milk was ok to drink. Then I read another study that says no association between dairy and Prostate cancer. Kind of confusing ! does anyone have an opinion on this
