Telephone Lifeline Support provides telephone numbers of IWMF volunteers who will answer questions about their first-hand experience with specific treatment for WM. IWMF also provides telephone and e-mail network lists that connect patients and caregivers. IWMF provides funding to researchers studying a treatment or cure for Waldenstrom macrogloblinemia or related blood cancer. Information on the Web site is available in French, Spanish, and German.
