      Hofvind, Solveig Sand-Hanssen; Mangerud, Gunhild; Holen, åsne Sørlien; Ursin, Giske (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-12)
      Hovedmålsettingen med organisert mammografiscreening er å oppdage brystkreft i et tidlig stadium og dermed redusere sykelighet og dødelighet av sykdommen. En ulempe er overdiagnostikk. Verdens helseorganisasjons kreftforskningsinstitutt definerer overdiagnostikk i mammografiscreening som brystkreft som ikke ville blitt diagnostisert i kvinnens levetid dersom hun ikke hadde deltatt i screening. Vi ...
