<s>[INST] Hi I have two swollen lymph nodes on my neck, one that has been there for 5 years and the other for about  a year. I recently done an ESR blood test because I was scared I had lymphoma . The results came back fine, with my ESR of 2mm/hr. Does this mean I don’t have lymphoma, or could I still have the disease. I am very worried and would like an answer ASAP! [/INST] Thank you for using healthcaremagic. You need to understand that lymphoma is not the only cause for enlarged lymph nodes. Lymph nodes can get enlarged in a number of situations like viral/bacterial infections, non-infective inflammatory conditions or cancer. Since the lymph node has been there for quite sometime, I suggest you undergo an FNAC (fine needle aspiration cytology) procedure, wherein the cells will be aspirated by a needle and a diagnosis can be given by studying the cells. Kindly visit a local pathologist for this procedure. Thank you. </s>
