Nature: Ding! Your AI doctor is online. Is AI better than human in cancer screening?

Author: what is the 21st century of Tang Jinghong? It's AI! Artificial intelligence is quietly changing our lives, such as smart phones, machine translation, image recognition, voice assistant, personality recommendation, etc it is no exaggeration to say that in modern life, artificial intelligence is almost everywhere In the 2015 movie "super Marine Corps," Dabai "is a robot with artificial intelligence, medical aid and combat capabilities Dabai can sense the vital signs, health data and emotions of the host, and then take measures to carry out health care With the rapid development of artificial intelligence, it seems that the dream of replacing medical staff with artificial intelligence robots has come true At the beginning of the month, nature published an article According to a study conducted by Google Health, AI systems are better than radiologists in breast cancer screening The team hopes the technology can be widely used to improve cancer care Https://doi.org/10.1038/s41586-019-1799-6 false negative and false positive mammography screening is a common breast scanning method, which can identify breast cancer at an early stage Although women in various countries will receive breast scans once a few years or even once a year, the results of screening are not always accurate For example, the results of radiation scanning may show "false negative" and "false positive" results The causes of these results are related to age, breast density, family history and other reasons, which may lead to misdiagnosis, resulting in the patients who think they are healthy, but the patients who should not be treated are over treated Big data in order to improve the diagnosis results, the research team from Google Health trained the AI system with 91000 mammograms taken from Britain and the United States They were followed up for two or three years to see if they had breast cancer Compared with the diagnostic opinion of radiologists, the results of the development of AI system for breast cancer screening by mammography show that the false positive results of AI system in the United States and the United Kingdom are reduced by 5.7% and 1.2% respectively In addition, the team compared the AI system with six radiologists Even when patients and family histories were provided to the staff, the performance of AI was 11.5% better than that of radiologists It seems that AI system can compete with radiologists The powerful evaluation ability of AI system improves the accuracy and efficiency of breast cancer screening and paves the way for clinical trials Intelligent medical treatment also makes us think again whether the development of artificial intelligence highlights the insignificance or strength of human beings Small is inferior to AI, but powerful is able to create and guide the development of AI AI still has a long way to go in the application of medical field I hope AI can bring us a better future Reference: [1] international evaluation of an AI system for breast cancer screening [2] AI system is better than human docs at predicting breast cancer [3] AI shows promise for breast cancer screening
