[|Human|] hello, I am 28 years old female,i have noticed a stiff round ball in left side of my neck.its slightly bigger than a peanut and moves when touched and it hurts too.I dont have any family history of cancer .What tests should i take and how can i know if its dangerous or not.
[|AI|]  Hi!welcome to Chat Doctor. All swellings need not be cancerous. Get a thorough check-up by a surgeon preferably to ascertain-type of swelling etc. An ultrasound will let you know whether solid-or cyst(fluid). If fluid most likely infection or inflammation. Biopsy can be diagnostic and therapeutic if fluid aspiration can be done in same sitting. Commonest swellings are lymph nodes from oral, scalp,ear infection. Take care. And let us know what you did.
