Highlights:
– Annual screening in women aged 40-59 does not reduce mortality from breast cancer beyond that of physical examination
– .Canada decided to compare breast cancer incidence and mortality up to 25 years in over 89,000 women aged 40-59 who did or did not undergo mammography screening
– During the 25 year study period, 3,250 women in the mammography arm and 3,133 in the control arm were diagnosed with breast cancer and 500 and 505, respectively, died of breast cancer
– Furthermore, the study shows that 22% of screen detected breast cancers were over-diagnosed
