I'm really worried about my mom. She's a diabetic patient and recently had some pain and inflammation in her right underarm. We went to a breast center where they did a mammogram with contrast, and the report said something about necrotic right axillary lymphadenopathy, described as BIRADS 4, and suggested a biopsy. They also mentioned some masses in her right breast, probably benign, and suggested to follow up in 6 months. There was also a simple cyst in her left breast and retroareolar duct ectasia in the right one, but they said it's benign. After that, she had a USG guided FNAC, and it came back with something called necrotising granulomatous lymphadenitis, which they said could mean TB. But we did all the TB tests like AFB smear, pus stain, X-ray, AFB stain, culture, and gene xpert, and everything was negative. They also did a biopsy by removing a lymph node, and it showed no malignancy. The doctor mentioned there were many lymph nodes, and a few had pus, so they checked for infections like HIV, HCV, and HBsAg, and those were negative too. I'm trying to understand why she has multiple lymph nodes, some with pus, and if this is something serious. Should we be seeing a specific specialist or doing any additional tests? This is so worrying, and we're not sure what steps to take next.
