Six-year-old boy who's suffered stroke and brain cancer desperately searches ...

Six-year-old Ayden Palmer has already battled through what seems like a lifetime of pain.

When he was three years old, he suffered a stroke that paralyzed the left side of his body. Last year, he battled brain cancer.

Now Ayden, from Prosper, Texas, needs a life-saving bone marrow transplant as he fights a blood disorder, reported Fox 4.

Ayden's best hope of finding a match is within his own ethnic group, but doctors say there are too few minority donors on the national registry and that he has just a 25 percent chance of finding a perfect match.

The disorder causes red blood cells to have a crescent, or sickle, shape instead of the normal round shape.

Sickle cells die prematurely, which causes a shortage of red blood cells. When they do pass through blood vessels, they stick together and block vessels, preventing blood from properly flowing. 

In December, Ayden underwent brain surgery to improve blood flow, according to Fox 4. 

It's unclear how well he's recovered from his past stroke and brain cancer battles. 

'He's known nothing but pain, and he's immune to pain. That's what I see,' Ayden's mother, Tut Palmer, told the station.
