The history and clinical presentation suggest that they are enlarged lymph nodes.2. The lymph nodal enlargement is seen in any inflammatory infective conditions it can be localized or systemic.3. I would suggest getting an ultrasound scan done for breast and axillary region - that will help to identify the nature of the lump, source and extensions.4. Depending on the findings you can decide weather monitor or need FNAC - fine needle aspiration cytology - to evaluate the nature of the cells involved. 5. If there is any underlying medical conditions - please get treated, as they do give the lymph nodal enlargement. Good luck. Hope I have answered your query,anything to ask ?
