Hi my son has a swollen lymph node in his groin, first measured around 8cm s, the doctor put him on a broad spectrum anti-biotic and it has now reduced to 3cm s. He has had the lump for 3 weeks and it is very hard. He had other symptoms with it, headaches, nausea, could not eat and has lost quite a bit of weight, which could be the result of him not being able to eat. He has all over body skin itching but only for a day or so. The Dr looked over his whold body for any sign of insect bite or infected scratch but found nothing. The lump was painful to start with but is not any more. He is feeling much better after this course of anti-biotic, had an ultrasound yesterday and should get the result in 7 days. Of course my concern is that this may be lymphoma. My question is that is it a good sign that the node is reducing or does that not necessarily mean it couldn t be cancerous. I would be grateful for your advice. Thank you
