Specializes in Pediatrics

Reactive node: A 0.5 cm lymph node is normal size to slightly reactive. Probably reacted to an infection or inflammation. Be observant of it but I wouldn't be concerned.

Lymph node: There is no average size but a lymph node under 1.5 cm generally is benign. Always god to have a complete exam
