Hi Amanda,
Sorry for the delay. Yes, nutrition and cancer is very confusing!

Dairy: I am not convinced that there is a need to avoid dairy with breast cancer. I recommend low fat dairy in order to avoid the saturated fats associated with increased risk in breast cancer. Dairy often offers an excellent protein source, calcium and vit D-much needed by breast cancer survivors, along with conjugated linoleic acids which may increase cancer cell death.

I don't know of any direct benefit from animal protein but I will say if you are stuggling with a poor appetite I would liberize diet as much as possible to be sure intake is adequate. In other words, if animal protein sounds good but you are afraid it will cause harm I would not recommend restricting it. It is more important to get enough calories and protein than it is the source/possible increase in saturated fat.
Paleo-I love crossfit (big proponents of Paleo) but not crazy about Paleo diet--especially for breast cancer survivors--too much saturated fat.
Ketogenic-I don't think this is sustainable plus I think there should be some enjoyment associated with food/meals.
Plant based diet-There is a great deal of support for following a low saturated fat diet (with moderate amounts of animal protein or without). I think this is most realistic and can be maintained over the long term.
If you are having trouble with diarrhea you may talk to your team about adding more soluble fiber (grains-like oatmeal are a great source) and keeping up with fluids.

I hope this helps.
