Hello12061948, I have talked with a doctor at our cancer center, he feels my high B12’s are probably due to inflammation since I have GI issues also. To give me peace of mind more than anything, he ordered blood work for several cancer markers. The results take about 3 weeks so I have to be patient. I’m thinking that he is probably right. I go for my colonoscopy at the end of the month so I think I’ve covered all the bases. I will post my blood results when I get them. Hope things are going well for you. Emy.
