What would you do if you had some kind of organ cancer, and you discovered that a replacement could be cloned for you?

I ask this cause it involves a very touchy subject, human cloning.

On one hand it could be massively beneficial, because there would be zero risk of rejection. On the other hand it could be a slippery slope where you clone a whole person possibly.
