Both Times


Cancer survivors who develop a second primary cancer again are likely to have the same type of cancer both times, say researchers at the University of Copenhagen. As they report in the Canadian Medical Association Journal, the researchers examined the cancer in the Danish population between 1980 and 2007. "The principal finding of this nationwide study was that excess risk of a second primary cancer was due mainly to a 2.2-fold risk of the second cancer being the same type as the first, whereas the risk of it being a different type was only 1.1-fold," the researchers write. The risk varies, notes HealthDay News, depending on cancer type.
