As someone getting well with an incurable genetic disorder while the world calls me crazy and generally tries to tell me to STFU because I must be making that up, I find comments like this ironic at best.

Good luck getting the word out if one person solved it rather than a member of a team in a large lab and yadda. More likely outcome: The "one guy" who cures cancer will be written off as a member of the lunatic fringe and have endless doors slammed shut in his face.
