I ran across this article that introduces a smart phone-based system that can tell the difference between benign tumours and their malignant counterparts with up to 100% accuracy. Compared to traditional tests which take up to weeks, this system only takes an hour to make the diagnosis. The benefits of this system are that only a small amount of tissue is needed, and it is relatively cheap to run. This would make it easier and more accessible for doctors to track cancer. The device is simply made of a miniature MRI machine connected to a smartphone with this app. The app computes the amount of vibrations from the MRI machine and provides the doctor with a read out. Within three years, this app could be regularly used in hospitals. Do you think this advancement in smart phones for something as serious as cancer is beneficial? Do you think it is a reliable method that could be used in hospitals? If an app can detect cancer, what is next?
