Thyroid cancer: ABaer ~ you cannot diagnose thyroid cancer with T3, (liothyronine)T4,TSH. Odd is the TSH is raised and so is T4. T4 should be LOW if TSH raised. REPEAT these blood tests and have MD check that and examine thyroid for nodules and enlargement. If you take oral T4 do not take meds for 2 -- 3 hrs before labs. thanks
