I think genetic diseases (aka "runs in the familiy") will stay as a selection factor. Would you prefer to have offspring with someone who has a family history of severe cancer or some autoimmune disease? I wouldn't. So once genetic desease reaches a problematic threshold (where medicine can not offset it), I'm pretty sure people will begin to talk about their families health history earlier in the mating ritual. Or test (and select) their embryos if the bad trait was passed on. Or at some point modify them. Which both will lower the spread of bad genes.
