Adam "Nergal" Darski, the 33-year-old guitarist/vocalist from Poland's greatest extreme-metal export, BEHEMOTH, has been diagnosed with a life-threatening form of leukemia, a cancer of blood-forming tissues of the bone marrow. The disease, for which Adam is currently receiving treatment at the hematology division of the Gdansk Medical University Hospital, has advanced to the point where he is in urgent need of a bone-marrow transplant. (A bone-marrow transplant is when special cells [called stem cells] that are normally found in the bone marrow are taken out, filtered, and given back either to the same person or to another person.) In light of this, Darski wants to remind everyone about the need to be on the marrow registry. The more people get tested and donate, the more of a chance for life there is for him and others in the same situation.Every year, more than 10,000 people in the United States are diagnosed with leukemia or lymphoma, and a bone-marrow transplant from an unrelated person is their best or only hope for survival. There is no data available on how many people die waiting for a match, but only four out of 10 patients receive the needed transplant. BEHEMOTH and the band's U.S. record label, Metal Blade, would like to thank everyone for their support and well wishes during this difficult time. The best thing we can all do right now is learn about the marrow-donation process, not only help save one of metal's leaders, but to also do the same for countless others out there struggling with the same disease. To learn more about how you can register to donate marrow, go to www.marrow.org. Fans wanting to help out, register for the marrow program, or who have questions on running a marrow drive may contact the organization Music Saves Lives by e-mail at [email protected] or by visiting Music Saves Lives online at www.musicsaveslives.org. Darski's fiancée, 26-year-old Polish pop singer Doda (real name: Dorota Rabczewska), has reportedly already donated her bone marrow but her tissue type is not believed to be a close enough match. As a result of Darski's illness, all of the band's previously announced shows — including those in Russia and the Baltic states in September/October and the U.S. tour with WATAIN in November — have been cancelled.
