Google is implementing some AI algorithms to detect breast cancer and it could provide better results than manual human detection.
Normally it is is done by X-ray but still its not 100% accurate.
Google's AI is trained to scan through these X-ray images and analyze the presence of cancer. It has been trained by 76k different samples from US and Uk.
It is still a work in development but hopefully it will improve with time and auto diagnose of cancer will be more easier than it is now.
