Patients with lymphoma generally present with painless enlargement of superficial lymph nodes as their initial symptom, most commonly in areas such as the neck, above the collarbone, and the groin. For diagnostic purposes, it is best, if possible, to conduct a whole-body PADCT scan as this helps in the staging of lymphoma at the initial visit. A definitive diagnosis requires the complete excisional biopsy of the affected superficial lymph node, followed by a pathological examination. An excisional biopsy is a method for confirming the diagnosis of lymphoma.
