JAMAEfficacy of Screening Mammography
1,063 Citations1995Karla Kerlikowske, Deborah Grady +3 more
Screening mammography may be effective in reducing breast cancer mortality in women aged 40 to 49 years after 10 to 12 years of follow-up, but the same benefit could probably be achieved by beginning screening at menopause or 50 years of age.

There was a consistent risk reduction associated with screening in all studies, although the point estimate of the relative risk for all ages varied non-significantly between 0.68 and 0.84.
The LancetIs screening for breast cancer with mammography justifiable?
860 Citations2000Peter C Gøtzsche, Ole Olsen
Screening for breast cancer with mammography is unjustified because for every 1000 women screened biennially throughout 12 years, one breast-cancer death is avoided whereas the total number of deaths is increased by six.

JAMAPeriodic Breast Cancer Screening in Reducing Mortality From Breast Cancer
475 Citations1971Sam Shapiro
The 3 1/2-year case fatality rates among women with histologically confirmed breast cancers reinforce the impression that screening leads to lowered mortality, and more time is needed to establish whether the effect of the screening program is short-term or long-term.

392 Citations1999FE Alexander, TJ Anderson +7 more
The findings confirm results from randomised trials in Sweden and the USA that screening for breast cancer lowers breast-cancer mortality and suggest benefit from introduction of screening before 50 years of age.

The authors' thorough review of ways in which the randomization could have been subverted failed to uncover credible evidence of it and it is concluded that even if there had been acts of subversion, they could only have been few in number and, given that there was only 1 death from breast cancer in the group reviewed, the alterations could have had only a trivial effect on the study findings.

The effects of screening will be small in the first years after the start of the programme, and the mortality reduction due to screening in the age group 55–74 is expected to increase gradually to 18% in 1999, 10 Years after the introduction of screening, and to 29% in the long term.
