The Lymphology Association of North America, LANA, is a non-profit corporation specializing in the certification of healthcare professionals who diagnose and/or treat lymphedema and related disorders. LANA was created following the 1998 American Cancer Society Lymphedema Workshop recommendation to establish certification guidelines to assure that specific treatments and facilities meet state-of-the-art criteria. The multidisciplinary LANA Board of Directors, including physicians, nurses, and therapists, identified the need for and subsequently created a national certification examination.
