AI Matches Radiologists’ Skill at Detecting Breast Cancer on Mammograms
An artificial intelligence (AI) system based on deep learning algorithms is able to detect breast cancer in digital mammography screenings as well as experienced radiologists, a study says. The findings of the study, "Stand-Alone Artificial Intelligence for Breast Cancer Detection in Mammography: Comparison With 101 Radiologists," were published in the Journal of the National Cancer Institute. Despite significant improvements in treatment and screening methods, breast cancer is still the most prevalent type of cancer in women and a major cause of cancer-related mortality, accounting for approximately 500,000 annual deaths worldwide. Previous studies have shown that large-scale screening mammography programs are highly effective at reducing breast cancer mortality. "However, current screening programs are highly labor intensive due to the large number of women screened per detected cancer and the use of double reading (diagnosis confirmation by a second expert), especially in European screening programs, which also leads to additional economical costs. Moreover, despite this practice, up to 25% of mammographically visible cancers are still not detected at screening," the investigators said. Considering the lack of breast cancer screening expert radiologists in some countries, finding alternative approaches to provide screening programs worldwide is crucial. Since the 1990s, specialized AI systems have been developed to identify and classi
