Artificial Intelligence Could Aid in Breast Cancer Screening, Study Shows
An artificial intelligence model outperformed certified radiologists in diagnosing breast cancer from mammogram images, according to a new study. This suggests that the system could be used in clinical settings to help facilitate earlier diagnoses, although future clinical trials will be needed to know for sure. The study, "International evaluation of an AI system for breast cancer screening," was published in Nature. Early diagnosis of breast cancer is critical because cancers are easier to treat earlier on, when the tumor is small and before the cancer spreads. Cancer screening helps in this because it can detect tumors before they start causing obvious symptoms. The standard of care for breast cancer screening is mammography, a breast imaging technique. However, interpreting mammogram images can be tricky, and it's not uncommon for radiologists to interpret them incorrectly. This can cause false positives, which lead to undue stress and anxiety, or false negatives, which means delaying potentially life-saving treatment. In the new study, researchers in the U.K and U.S. tried to mitigate this problem by having an artificial intelligence (AI) system — rather than a human — interpret the mammograms. In principle, this kind of AI involves feeding data to a computer – in this case, both mammograms and cancer diagnoses (based on subsequent biopsies and othe
