Someone in the U.S. is diagnosed with blood cancer every three minutes. And although about three in ten blood cancer patients can find a matching donor in their families, 70 percent of patients depend on a stranger to step in. That was enough for me to know I wanted to help.

I registered online with Delete Blood Cancer.1.Four years later I got an e-mail from the organization and it said I had a possible match. To make sure all systems were a go, I had a couple of extra blood tests. I needed to donate bone marrow (骨髓).2.And my bone-marrow recipient was a little girl.

Four months later, donation day arrived. At 9 a.m., the procedure started. By noon, I was already on my way home from the hospital.3.My legs were sore, like I had bruised my bone or something. The doctors said the pain would gradually disappear a few days later.

4.The discomfort was secondary to the emotional high of helping a little girl with cancer. To me, it doesn’t matter that I’ve never met the girl who received my bone marrow or that I don’t even know her name. I still feel like I have such a powerful connection with her.5.

A year later, I haven’t heard how my bone-marrow recipient is doing, Delete Blood Cancer hasn’t come back to me asking for another bone marrow donation, so I hope that’s a good sign. But if they do call me back, whether it’s for her or someone else, I’d do it again.

A. I won’t lie—for a while, I was in pain.

B. I immediately broke down into tears on the phone.

C. There’s something in our DNA that brought us together.

D. That’s most often the case with young blood-cancer patients.

E. Even though the doctors gave me painkillers, I didn’t try any.

F. I met with all of the doctors who would be performing the procedure.

G. Then my DNA was collected to see if I was a match for any patients in need.
