Diet - Eggs or no eggs?

I am just beginning ADT ( Gleason 7 4+3 T2a ) and see the oncologist tomorrow here in France to set out the RT plan. No dietary advice so far from eg urologist and guessing that tomorrow will only be a practical regime for the duration of the RT. Respected sources constantly recommend a plant-based diet ( already on this ) with little or no dairy products. However, the court seems to be out in the matter of eggs. This concerns me, since B12 is clearly important on all fronts and calcium is clearly an issue with risk of bone thinning whilst on ADT.

Has anyone here received advice for or against please?
