Tattoo Machines Could Be Used in Healthcare

Can tattoo machines really be used to deliver medicine below the skin rather than ink?  Is this the future of healthcare in dealing with skin cancer or psoriasis? The studies are in the early stages but look promising and makes a lot of sense when you think about it.

This could be the next big medical breakthrough, helping people with a variety of skin conditions.  Its amazing to me that a tattoo machine, originally invented by Thomas Edison as an electric pen that was modified to introduce ink into the skin may now see another transformation into a medical tool used to inject drugs just below the surface of the skin.

If this is the future, does that mean we may end up going to see Dr. Massacre?
