"Man Saves Wife’s Sight by 3D Printing Her Tumor.
When his wife was misdiagnosed, Michael Balzer used 3D printing and imaging to get her well"

With your own health data and access becoming easier to revolutionary medical advancements, you should expect to see more stories like this. You are your own best health advocate, and your time is worth more than a single doctor's experience. You can dig longer and further than someone who needs to get you in and out in 15-30 minutes.
EDIT: A good example is my wife's endometriosis. There is no cure, just treatment. I'm working on a non-profit program to have genetic testing done for volunteers to isolate the parts of the genome responsible for endometriosis (statistical analysis; just like 23andme does) so that research can move to removing the responsible genome section using the recently discovered CRISPR protocol: http://phys.org/news/2015-03-crispr-technology-precise-genet...
Understanding how cells and populations of cells grow, from a 3 dimensional and spatial perspective, is a fundamental step in understanding our biology because it's research rooted in math and the real world. What do cells actually, physically look like, and how do they interact? These are questions biologists barely have the answers to, if they have them at all, and only recently have we unlocked the ability to try to answer them. Cancer research is a main beneficiary of super computing because it allows us to build simulations much closer to reality than we previously could.
Don't take the ability to 3d print a tumor for granted!
Neri is an architect who says her work is 'biologically inspired'. BS Central.
