How can i tell if i have castlemans disease or lymphoma?

Biopsy: Biopsy. The presentation of cd and lymphoma can be similar and may require a center that sees more of it to review. Here is a patient oriented review: http://www.Mayoclinic.Com/health/castleman-disease/ds01000.

Biopsy if necessary: If there is significant lymph node enlargement, a lymph node biopsy is necessary to make this distinction; however, a biopsy is indicated only if your physician considers it necessary after a thorough clinical examination.
