@irontoenail - Unfortunately, green tea, and all the other hot drinks, have been associated with mouth and throat cancer, simply because people will often drink them when they are too hot.
If people are habitual tea drinkers, putting a bit of cold milk into the tea before drinking it can cool it down enough to make a difference.
They've also shown that the increase of fancy, milk based coffees has directly led to lower levels of osteoporosis in women.
So, don't throw out the milk altogether if you're really attached to it. Maybe have a couple of cups with milk and a couple without milk or something like that.
Or, if you don't like drinking milk in your tea, you might want to consider letting it sit for a while before drinking it.
It's burning that damages the tissues and leads to cancer later on. If your tea isn't hot enough to burn your mouth, then you are fine.
