[|Human|] My son is 3.5 years old and always been very healthy. Two months ago he had a stomach virus and a cold and threw up twice in one day, while I was changing him I noticed a small lump above his belly button. I made an appointment and after having an ultrasound, x rays and blood test the Dr said its not cancerous, all tests are good and its most likely a lymph node only 1 cm big. He said it was in a harmless location and probably was swollen due to the virus. Two months later he still has it and it has not changed at all.
[|AI|]  Hi, The information regarding the swelling is inadequate. Is there any other swelling at other parts of body? Lymph node swelling has got typical texture, consistency, surface, margin and that can be clinically accessed. Any swelling like this may also be lipoma. Anyway from this information the swelling seems not to be serious. In case appearance of other swelling you should inform your doctor. Take care.
