Myelodysplastic syndrome (MDS) — also called preleukemia or smoldering leukemia — is relatively rare, affecting fewer than four in 100,000 people. The experts at Roswell Park have extensive experience in diagnosing and treating the condition and managing its side effects. Our MDS practice is one of the most active in the nation, with more than 500 visits by MDS patients every year. The MDS Foundation has classified Roswell Park as one of its MDS Centers of Excellence in the United States. Whether you are seeking care as the result of a relapse or new diagnosis, we’ll create a comprehensive treatment plan tailored specifically to your needs.
