hello, my right lymph node is swollen and my white and red blood cells have come back normal. I was negative for strep and I have no symptoms other than some fluid behind the ear. I was ordered a biopsy and was wondering how a doctor determines if they re doing and FNA or an open biopsy? I can t remember if she said it was a centimeter big or an inch. But it is very large and can be seen without me lifting my chin. I don t like needles so I m just trying to prepare my mind and scaredy cat self. Thank you so much and have a good rest of your night.
