Full of energy, Sebastián aspires to be a professional soccer player in the future.
To play professional soccer has always been Sebastián's dream.
Nothing prepared Sebastian’s parents, Belén and Andrés, for the day in June 2014 when they learned he had a rare cancerous brain tumor called a medulloblastoma.
“We were devastated,” said Belén, Sebastián's mom. "Sebastián had always been a sweet, caring child with an adventurous heart. It was difficult to imagine he was so sick.”
Families, like Sebastián's, will never receive a bill from St. Jude for treatment, travel, housing or food.
At St. Jude Children’s Research Hospital, Sebastián's treatment included four rounds of intravenous chemotherapy, six weeks of radiation therapy and a year of oral chemotherapy.
Sebastián participated in a commercial for the 2021 St. Jude Thanks and Giving® campaign with actress Sofía Vergara
We have no words to describe St. Jude. Everything is designed so families only have to worry about their children.
Sebastián is now finished with treatment, in remission and returns to St. Jude annually for checkups.

His favorite subject is math and he is currently enrolled in an advanced mathematics course. Sebastian also plays percussion in the band.
“He’s a really good student and very responsible,” said Belén.
In addition to his dream of playing professional soccer, Sebastián expresses interest in becoming an engineer in hopes of “creating a machine that cures cancer in kids.”
