You do not tell us why you believe you have cancer. Your vitamin B12 levels are fine. Suggest you seek out your regular doctor and undergo a full physical exam, including blood tests, a chest X-ray, and possibly a colonoscopy.

My vitamin B12 levels are high. 1136 to be exact. The doctor isnt concerned and said dont worry about it, but I dont take supplements. Do I need to get a second opinion? I just read high levels of b12 can signal cancer?
