Worried about cancer. Should I be? I had my blood drawn. Protein total 6.9. Albumin 4.9. Globulin 2.0. Albumin/globulin ratio 2.5. Is this normal?

You're fine. Reference ranges are set so that several percent of healthy folks fall outside. If you have no localizing symptoms, your physical exam (including testicular check) is nonrevealing and your complete blood count is normal without bizarre cells, you're almost certainly not sick with cancer.
