When Dr. Nick Mondek learned his cancer had returned this spring, he didn’t know that his 10-year-old son Stephen would eventually become his lifesaving hero.
“Stephen is proof that real-life heroes come in all shapes, sizes and even ages,” Mondek told ABC News. “They may be right in front of us, and we don’t even know it, and in one act of bravery and courage, they can completely alter your life.”
Mondek, a Los Angeles anesthesiologist and father of two, had previously undergone chemotherapy and a stem cell transplant for acute myeloid leukemia, a type of cancer of the blood cells. His older brother Dave had donated his stem cells to him in 2022.
This time, Mondek told ABC News he turned to extended family members and the National Bone Marrow Registry, but he didn’t find any suitable matches.
“It was a dismal prognosis, and I needed a donor immediately, and there was no one available,” Mondek said.
People with acute myeloid leukemia typically need treatment sooner than later, as the cancer may worsen quickly, according to the National Cancer Institute. Doctors may treat this type of cancer in a variety of ways, including with chemotherapy, radiation and stem cell transplants, and for Mondek, he said another stem cell transplant ended up being his last option after undergoing chemotherapy and radiation.
Doctors at Cedars-Sinai successfully extracted stem cells from Stephen, and Mondek received his second stem cell transplant on July 30.
The proud dad called his son his hero and a tough boy who “never complained once.”
“He didn’t have to put on a cape or leap buildings in a single bound. Instead, he put on a hospital gown and gave me hope,” Mondek said. “I’m not just honored to call this boy my son, I am just as honored to call him my hero.”
Stephen told ABC News’ Los Angeles station KABC that he had support from his peers as well.
“It feels good to do that, because all my friends are proud of me,” the 10-year-old said.
Both father and son are now out of the hospital, and Mondek said Stephen is doing great.
“Within three or four days, he was already back at baseball practice,” said Mondek.
Mondek said he’s on a long road to a new normal, but currently, his prognosis looks promising.
“They did a blood test last week for the first time to screen my blood for any of the DNA of my leukemia cells, and they couldn’t find any,” said Mondek. “So, as of right now, I’m still in remission, and there’s no sign of cancer.”
