When Mary-Elizabeth Sierra Lanham had her eyes checked for near-sightedness, the routine exam showed that the optic nerve in her right eye was swollen.
A string of visits to different specialists led to an MRI that finally explained the problem — a lump in her head was pressing against a major vein.

That was when mom Sally Lanham brought Mary-Elizabeth to Children's, where blood and bone marrow samples confirmed that her daughter had acute lymphoblastic leukemia (ALL), a type of cancer where malignant white blood cells or "lymphoblasts" are produced in the bone marrow and can spread into the bloodstream and vital organs.
ALL accounts for approximately 25% of all childhood cancer.
Although Lanham didn't know it, her decision to switch Mary-Elizabeth's care to Children's may have saved her daughter's life: Teenagers and young adults have a much better chance of beating ALL — more than 25% better — when they receive pediatric cancer treatments rather than those intended for adults.
Separate studies in North America, France, Netherlands and Italy confirm these findings.
Among institutions treating teens for cancer, Children's has some of the best survival rates in the nation — in fact, ours are far higher than the national average.
The five-year survival rate for ALL patients ages 15–19, diagnosed from 1996 through 2002 and treated at Children's, is 85%. The national average for the same group is just 55%.
For all forms of childhood cancer combined, Children's five-year survival rate is 82%, well above the national average of 76.4%.
