Is there any real conclusion of how advanced medical care is in canon in the GFFA? I mean they have real prosthetic limbs, and Mara's illness in the EU, but there's also the fact that Anakin was too badly damaged post Mustafar for them to restore him to health so there's obviously things they can't fix, but then you have also in canon Mara being restored to full health in the Zahn trilogy and them being able to fix damaged nerves. I was wondering how plausible the idea of genetic defects and terminal illnesses like cancer and leukemia would be in the GFFA. As far as writing them, leave the Earth name or come up with something else entirely different so as to not wrench the reader out of the star wars universe? Any advice is welcome and would be greatly appreciated.
