Why Was This Test Ordered?
Your healthcare provider may have recommended this test if you experienced symptoms like persistent sore throat, unusual lumps, difficulty swallowing, unexplained weight loss, or unexplained bleeding. It could also be part of routine monitoring for known conditions like cancer or chronic infections.
What to Expect Before the Test
You may be asked to avoid eating or drinking for a few hours before the procedure. Bring any medications you’re currently taking, as some may need to be temporarily stopped. Inform your doctor about any allergies or conditions that could affect the biopsy.
What Happens During the Test?
A healthcare professional will use an endoscope—a thin, lighted tube—to visualize your throat and neck. Small tissue samples will be taken from the affected area under local anesthesia to minimize discomfort. The procedure usually takes about 15–30 minutes.
What Happens After the Test?
You may feel mild discomfort or soreness for a few hours. Avoid strenuous activities for the day. Follow-up instructions from your doctor may include eating soft foods, staying hydrated, or monitoring for signs of infection.
