The most common type of childhood cancer is leukemia. While leukemia can often be treated with chemotherapy, some children require a bone marrow transplant. Siblings and parents are tested first, but if they don't match, the only chance is a stranger match through the bone marrow registry.
The only way to get a stranger match is to have a large group of donors to choose from. The best matches are often from donors with a similar ethnic background, so a variety of donors are needed. Joining the registry is easy, but make sure that you are ready to commit to a bone marrow donation before joining. These patients are counting on you to help them survive.
If you aren't able to commit to donating marrow, consider donating financially. It can cost hundreds of dollars for all of the testing required for donors before they can join the registry. That also doesn't include costs for the donation.
Please consider either joining the registry or donating to help those who can't afford to but still want to give marrow. bethematch.org
