From a The Verge online article:
The tool is simply called Preventive Health, and is now available to Facebook users in the United States. It takes a user’s age and sex from their Facebook profile and provides them with a list of recommended screenings based on those two data points.
“Let’s say you’re 52 years old,” Freddy Abnousi, Facebook’s head of health care research, tells The Verge. “One of the things that will come to you — based on the American Cancer Society’s recommendations — is that you should have a colorectal cancer screening.” Abnousi says that the app will then give you more information about what kinds of tests are available, from a colonoscopy to a stool test or a CT scan. Abnousi hopes that users will then take what they’ve learned and talk to their primary care physician about what would be best for them. Users can also adjust the age and sex in the tool to get different screening recommendations without having it affect anything on their profile.
