Welcome to health care magic. Considering thd young age and the presentation with anemia and mutiple abdominal lymph nodes, one should evaluate him quickly without wasting time and i would have seng such a patient for a CT scan of abdomen and then lymph node biopsy
for definitive diagnosis. We need to rule out significant conditions like lymphoma
, etc. And the treatment for each is completely different and most conditions among those mentioned above are rapidly progressive unless treated urgently. Hence, i would suggest you to consult a physician soon.
Happy to help you.
