As long as it works, that's the main thing.
And the bonus of scaring people shitless when there's a "glow" when you go for a leak in a public restroom is priceless.
I know some may think I'm a rather unfeeling bastard in this respect, but I found a dark sense of humour can do more to help in such severe cases when I had the joys of watching my mother suffer from a different type if cancer, for if you don't laugh you cry and, well, laughter is the best medicine because it keeps you in a positive mindset.
You can beat this, and beat it so hard it will never know what hit it. Don't ever let the bastard get you down, for the second you do is the second something with good survival rates wins.
