Peyton and her mom
Peyton is now 7 years old. She’s been cancer free for two years.

In the summer of 2019, Dianna Cooley started noticing signs of illness in her daughter, Peyton Cooley, who was producing low-grade fevers. After multiple trips to urgent care and their provider sending them home with antibiotics which seemed to show no signs of improvement, Cooley walked herself and her daughter through our hospital doors.

Dianna’s gut feeling that something was wrong with Peyton was swiftly reinforced by a diagnosis from our children’s hospital. Peyton was 3 years old when told she was suffering from Acute lymphoblastic leukemia (ALL), a cancer in which the bone marrow makes too many lymphocytes or a type of white blood cell.

After two weeks, she was admitted to our Comprehensive Cancer Center to receive her first dose of chemotherapy.

“When we first got to UC Davis, Peyton was really scared,” Cooley said. “But we had awesome support from everyone at the pediatric infusion center. They really helped me, too.”
