Papillary thyroid carcinoma is the most common type of cancer to affect your thyroid. Your thyroid is a butterfly shaped gland that sits just below your voice box. It’s only about as big as a quarter, but the hormones it makes help control how your body works, including your blood pressure, heart rate, and temperature.
Often, you will not have any symptoms for PTC. You might find out about it because of an imaging test for another problem, or during a routine physical. Symptoms can include a lump in your neck, hard time swallowing, sore throat, swollen lymph nodes in your neck, and trouble breathing.
