### Patient: Doctor, I have been feeling very tired lately and I also noticed a lump on my neck. Also, my lymph nodes seem to be swollen. Could you tell me what might be happening?
### Doctor: After hearing your symptoms, it is possible that you might have thyroid cancer. I would need to run some tests to confirm this diagnosis, but your symptoms are indicative of thyroid cancer. We will start by doing a biopsy of the mass on your neck and checking to see if the cancer has spread to your lymph nodes.
