What do you think about me refusing to donate a kidney to my mom
Why do you want to refuse giving your mom a kidney?
My mom is only 50 and she does not have cancer.
Choosing to donate an organ is up to you and it's not something that you should feel pressured to do. You should make an informed decision whether you are in favor of or against organ donation. This will ensure that you are not left with regrets about any decision you make.
I have enough reasons to not do it. If a family member of mine was in a similar situation, I wouldn't help them either.
It's your right to decide what you are going to do with your organs. Just be sure that you are making a choice that you will not regret in the future.
