The biopsy is going to check for cancer..A cyst is just a cyst they can be rmoved most of the time they are non cancerous..The lymph node may be enlarged did they say that??What exactly did they expalin to you?
My grandma had a biopsy done a few months ago she didn't have any issues with it said it wasn't painful (but this is a strong woman)
My best WISHES sent your way..Let us know how it went tomorrow
