I can understand your concern. You have enlarged lymph node in abdomen. You should go for ct scan abdomen to rule out any cancer or major pathology. Lymph node more than 1 cm in size is significant. So go for ct scan and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
