Hi! this kind of recurrent lump indicates lymph node enlargement and If I were your treating Doctor for this case of axillary lymphadenopathy, I would come up with three possibilities, these include: 1. lymph nodes due to some chronic inflammatory but simple conditions like chest infection, ear/nose/throat infection, common cold etc. not to worry and no therapy required! 2. The second possibility is of tuberculosis or chronic viral infection. these are potentially curable conditions! 3. The last possibility is of malignancy like lymphoma or metastatic cancer from throat, lungs, gut, tongue or thyroid etc. ! I suggest you to go for an FNAC/BIOPSY test from the lymph node for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
