If you could cure the world of one medical ailment what would it be?

Cancer. I've seen too many people die from cancer. If I could I would cure it.

Apart from cancer, I'd like to see a real cure for depression.
So many people's lives are ruined by this.

For me and for selfish reasons it would have to be epilepsy, to have to watch someone you love fit and know there is nothing you can do or say to help them breaks my heart every time it happens. I know most people will say it isn't life threatening but a friend of ours died having an attack and when you have to start your own daughters breathing during one of her fits you really get a new perspective on it.

Cancer. also if possible cystic fybrosis to.

The big C is certainly one to cure. Up next, possibly HIV.

Saying that, curing the common cold may be a good one too - less lives saved, I admit, but quality of life increases.

The last one to cure, once we've sorted out a whole bunch of other stuff, would be old age. I'm including this as an "ailment" as basically all your organs start to deteriorate. However, curing this is a two edged sword as then there'd be a population explosion unless we all stop procreating :-)

I would opt for a cure for cancer, since both my in-laws died from the disease, and suffered long painful deaths. Noone should have to go through that, in my opinion.

It would be cancer, multiple sclerosis, cystic fybrosis, Aids or flu

I would cure people with lung problems because i was born with pneumonia i know that my lungs really are bad, and i know when im older im going to have to be one of those people that have to carry and oxygen cylender round with me for when im out of breath, i get like that when i have a cold so i know its going to happen because my lungs are nackered so i would cure that.

Despite both my parents dieing of cancer, I would still go for excessive fertility - strictly speaking a global, rather than human ailment.

Heart Problems my mum had a heart attack in Jan and i was so scared she was going to die, so that then Cancer then Epilespy as i have had it for years.
