Do you think the storage of the umbilical cord blood cells of your child can be useful in the future? - umbilical cord storage

I asked this question in the medical field, but I wonder what the mothers and soon-to-be-thinking mothers.

How can I take seriously what kind of "help" if someone is a serious illness in my family? Some doctors say it's just a waste of money because no one has recovered again for this reason, although some doctors say it may in the future and benefit from the blood cells can be used in more and more as technology and medical Research is growing.

It is uncertain whether the cells in addition to the child as a donor, it may happen that even if the cells were stored, family member illness can not be recovered may be used. Despite the fact that there are many questionable information on the storage of cord blood, you think it's worth it because we do not know what events are before us or not recommend?
