In September 2023, just two months after his mother fought and won a battle against breast cancer, Sam Lane began to get sick.

Sam underwent several rounds of testing, and the now 14-year-old finally received a diagnosis: a rare brain and spine cancer.

“They said ‘cancer,’ and before I started crying, I said, ‘Dang it, I was going to guess that, but I didn’t want it to be that bad,’” Sam said.

But at his lowest point, intubated and unable to walk, a nurse offered Sam a bright spot: She said she needed his help to build a Lego MRI scanner set for fellow patients at Boston Children’s Hospital to play with and learn from.

Sam’s mom said she was “blown away” by the level of detail in the play set, made of specialized Lego bricks.
