Preoperative Hemogram Parameters and BRAF Molecular Test Detected by Bethesda 3 Cytology.

This observational study is examining whether routine blood test results (like white blood cell counts, known as a hemogram) and a genetic mutation test (BRAF) can help predict which thyroid nodules with uncertain results on needle biopsy (called Bethesda III or "indeterminate" results) are actually cancerous. The goal is to improve decision-making around thyroid surgery. **You may be eligible if...** - You are between 18 and 75 years old - Your thyroid nodule biopsy came back as "indeterminate" (Bethesda III classification) - You have been scheduled for thyroid removal surgery (thyroidectomy) **You may NOT be eligible if...** - You have cancer in another part of your thyroid besides the nodule being studied - Your preoperative blood test (hemogram) results are not available - You decline to participate in the BRAF genetic testing Talk to your doctor to see if this trial is right for you.
