Free of supervision, deep learning algorithms can be trained to work faster and smarter than humans. Perhaps more importantly, they can also be used to diagnose diseases, including cancer. Just how effective is deep learning in a medical setting? Last year, researchers at the Houston Methodist Research Institute developed AI software that can accurately diagnose breast cancer 30 times faster than doctors can. In other words: very effective.
Before we dive deeper, here’s a quick refresher on deep learning from Karen Panetta, IEEE Fellow and Dean of Graduate Engineering at Tufts University: “Deep Learning is a field of AI that looks at massive amounts of real data to extract behaviors and trends. Then, when the AI is presented with something it has not seen before, it can tell you what it is with excellent accuracy.”
By checking its responses against an answer key to see how well it did, AI can then rearrange the patterns and run the data set again to see if it achieves a better result. You can read more about the learning process on IEEE Spectrum.
So, back to health. This iterative learning process means AI can be trained to look for and diagnose cancer based on sample medical images prepared by researchers.
To understand why that’s such an exciting proposition, consider the current setup. IEEE member Sukanya Mandal: “Currently, cancer is being diagnosed by visual examination of tissue samples under a microscope by considering factors such as cell shape, mass, number and appearance.
As the diversity among cancer cells is high, it becomes very difficult to assess every variation with the naked eye, especially things like the morphology of cells, the arrangement of cells within a tumor and the genetic diversity of cancer,” says Mandal. Therefore, AI could well be the difference maker in judging whether tumor cells are malignant or benign. That accuracy could then help prevent unnecessary surgeries.
But the potential power of AI doesn’t stop there. We’ve written before about a machine learning system that studies lesions, demographics, family histories, biopsies and pathology reports, and uses all of that data to better predict if a certain lesion will develop into breast cancer. Software also already exists that diagnoses breast cancer with 99 percent accuracy when looking at mammogram results and medical histories.
The excitement regarding this technology is profound. In our global survey of 2,000 parents aged 20–36 years-old, a majority in China (85 percent), India (83 percent) and Brazil (70 percent) all think AI medical breakthroughs will eradicate cancer in their children’s lifetime.
