Google has developed an artificial intelligence system which detects the breast cancer. This systems detection is more accurate than doctors.
This system was developed through collaboration between the tech giant and cancer researchers.
The study which tested the accuracy of this system is published in the Scientific Journal Nature.
To train the system to detect breast cancer, the team used volunteers from UK and US. Early research shows that it can produce more accurate detection than human radiologists or doctors.
According to this research the system also has very low false positives and low false negatives. False positive is wrongfully detecting cancer even when its not present for real. False negative is, not detecting it even when the real thing exists.
Unlike the human radiologists and doctors, this system requires less information to detect cancer. It detects more accurately even if the information such as patients history is not provided.
Professor Ara Darzi, one of the authors of the paper and the director of the Cancer Research Uk Imperial Center has not expected such and impressive result from this system.
Breast cancer is the second leading cause of death for women. The disease can be cured if detected early. Currently even the largest scale breast cancer screening programs in developed countries fail to detect one in five breast cancers according to American Cancer Society.
“The performance of even the best clinicians leaves room for improvement,” the study’s authors wrote in Nature. “AI may be uniquely poised to help with this challenge.”
This technology also can be used as a solution to the shortages in radiologists. The report forecasts that nearly 2000 additional radiologists would be required to close the shortfall in 2023. In places where two radiologists interpret each mammogram, the AI system can replace the second radiologist allowing him to perform another mammogram.
The study was published on Wednesday as a collaboration between Google Health, Cancer Research UK Imperial Center, Northwestern University and Royal Surrey County Hospital.
