<s>[INST] i have noticed 2 lumps on either side of my neck for around 12 months now but forgot all about them until recently, the one on the right is getting bigger...more of a grape in size than a pea. I am a fit healthy 30 year old women, i run alot.I have no pain with the lumps. what could they be?My Granda died of throat cancer and never smoked a day in his life. I do not smoke but just a tad worried [/INST] Welcome to Chat Doctor. 1. The lumps in the neck on bilaterally suggests lymph nodal enlargement at first place followed by thyroid swelling. Followed by any glandular or lipomatous.2. Lymph nodal enlargement is seen in case of any infection / inflammation / malignancy and lymph nodal pathology itself (lymphadenopathy) 3. The diagnosis can be done with the help of an ultrasound neck, which helps to evaluate the nature of the lumps, its source and extensions.4. For definitive diagnosis - an FNAC - fine needle aspiration cytology will help to evaluate the type of cells involved.5. Sugget to get an appointment with your GP, examined, investigated and treated accordingly. Good luck. Hope I have answered your query,anything to ask ?
