why milk is bad reasearch

I've been researching why cow's milk is bad for people. I was very surprised by some of the things I found. In one website It said that every milk has some amount of puss and blood from the cow. In another website I found out that it can give you cancer because farmers inject this bioengenieered hormone into the cow. This hormone affects cell growth causing quick growth in humans or any other animal. Cells are instructed to die or stop dividing so that the creation of new cells is matched by the death of cells and no net-growth occurs. If this is prevented then cells don't die at the right time causing uncontroled cell division (cancer). The point is milk can cause cancer.
