Undecided. For the very few instances that a child could be their own donor of stem cells, they can harvest the stem cells if/when they need them. Most situations, however, that involve stem cell transplants are cancers that you can't be your own donor anyway. I go back and forth and haven't decided what to do yet. Leaning towards donation because like I said, if you can be your own donor, its because its a cancer that is a solid tumor and there is nothing wrong with your stem cells (unlike leukemia) and they can harvest the stem cells when they need them. There are many children whose family members aren't a match for them, and if by some chance our cord blood was a match for someone, I'd rather they have a chance at life then preparing for something that most likely will never happen.
Great question! Thanks for bringing it up. Being a pediatric nurse, I thought I was the only one thinking about this.
