Benefits
Signs of Calvin's cancer emerged in June 2018 when after a family bike ride, his mom noticed his leg was swollen and he had a bumpon his back.
A CT scan led to a scary diagnosis. Calvin had stage IV rhabdomyosarcoma, a cancer of the soft tissue, with tumor growth in five places: his pelvis,hip, stomach, lung and neck.
As his parents discussed treatment options with their medical team, something one doctor said stood out: “He said, ‘If it was my kid, we'd go to St. Jude,’” said Calvin's mom. “We had no idea what we were up against. No idea. We just knew that this was the best place.”
At St. Jude, Calvin underwent chemotherapy, proton therapy and radiation treatments. Through it all, he showed a lot of determination and channeled his feelings into art. “Calvin is strong-willed,” said his mom. “He fights through the pain, and he's a really happy kid.”
Calvin experienced a recurrence of rhabdomyosarcoma in 2020. He completed relapse treatment and now returns to St. Jude for regular checkups.
