(Brenner et al. 2000)

(134%), lung (61%), oesophagus (106%), leukemia (71%)

(EBCTCG, Lancet 2005)

Breast

: compared to no RT: ERR= 45% for sites with D>1Gy (lung, oesophagus,

pleura, bone, soft tissue), ERR=9% for contralateral breast ca (D≈1Gy), no evidence for

enhanced risk for D<1 Gy

(Berrington de Gonzalez et al. 2010)

Cervix

: compared to general population: for all latency periods ERR(D>3Gy) >

ERR(1Gy<D<3Gy) > ERR(D<1Gy). 10-19y: 53%, 22%, 12%
