I understand your concern. However, almost every person has palpable lymph
nodes in the groin. In your case, they are of concern if they have more than 15 mm in its largest diameter or if they start to enlarge. If you have done recently a CT scan
of that area and it says you are in remission, that means that you have normal lymph nodes. So calm down and do not worry, unless these lymph nodes start enlarging. Hope to have answered your query.
