<s>[INST] painless hard either cyst or swollen lymph node/gland in my groin area. in an awkward & embarrassing spot spot. under the skin mass. i am female, age 22. no other symptoms. prior to this incident, about a month ago- had swollen lymph nodes in my arm pits and necks that went away on their own without antibiotics.  should i go to the doctor about this "lump"? could it be lymphoma? [/INST] Welcome to Chat Doctor. 1. The history and present symptoms and location suggest enlargement of the lymph nodes.2. In this case It's for sure that there is some lymph nodal pathology which needs to evaluate.3. Get an ultrasound of the lumps scanned, the ultrasound will help to assess the nature of the lump, its source and extensions.4. Followed by an FNAC - fine needle aspiration cytology will help in assessing the nature of the cells and possibilities of lymphomas.5. Possbilities of being lymphoma are there. So get scan and needful treatment. Good luck. Hope I have answered your query.Anything to ask do not hesitate. Thank you. </s>
