<human>: My doctor wants to perform a biopsy on my thyroid gland. What should I expect?
<bot>: You may experience some discomfort during the procedure, but it is usually minimal and can be managed with medication. The doctor will numb the area around your thyroid before inserting a needle into the gland. He or she then removes a small sample of tissue for testing. This is done to determine if there are any abnormal cells present in the gland that could indicate cancer.
