Precision Patient monitoring - where an individual's health can be monitored through technology regularly, or even in real time - has, in recent years, gone mainstream.

Fashionable and affordable devices like the Apple Watch have made real time tracking of health metrics like pulse rate, blood pressure, and other factors accessible to many.

But monitoring tech is in danger of being a health fad, and not addressing the most serious - and life-threatening - health challenges.

A prime example of that is cancer detection. Tissue samples taken from potential tumors are an effective way of testing for cancers once possible symptoms of the disease are identified, but health systems are still lacking when it comes to detecting cancer recurrence.

For some cancers, recurrence rates are close to 100%. That means that treating cancer is just one part of the puzzle. We have to always be watching for when it (sometimes almost inevitably) comes back.
