Early signs of cancer present in the fine detail of mammograms

HIGHLIGHTS

SUMMARY

    Mammograms of women taken 3 years prior to their eventual diagnosis (priors), that did not contain detectable cancer even when viewed retrospectively, are scored as significantly more abnormal than mammograms of women that did not go on to develop cancer in the near future.
