Are you starting with meat? If so maybe start vegetarian and then work towards being vegan as you figure out solutions. My reading of the B12 and cancer literature last I looked was that it wasn't as clear as some papers made it seem. I got the sense that the hypothesis that it exacerbates cancer might have been sort of post hoc to explain unreplicated findings. If you search for "mendelian randomization" and B12 and cancer, for example, IIRC, you'll find studies suggesting the prostate cancer B12 association (the only one remaining) isn't "real". But I could totally be wrong and haven't read into it in a while so I could be convinced of the opposite of my current understanding. I think I'm the end you just have to do what you think you can one step at a time.
