Isabella first shared her diagnosis during a segment onGood Morning Americaalongside her dad. She was diagnosed with the condition in October after she started experiencing headaches — which she initially attributed to vertigo — during her freshman year at the University of Southern California.
“I definitely noticed headaches, nausea, couldn’t walk straight,” the teenager toldRobin Roberts. Her condition took a turn for the worse on Oct. 25, when she woke up in the early hours of the morning “throwing up blood.” Her family encouraged her to seek immediate medical attention.
Doctors discovered Isabella had developed a fast-growing, 4-centimeter tumor, larger than a golf ball, in the back of her brain. She underwent emergency surgery at Cedars-Sinai to remove the mass on Oct. 27, a day before her 19th birthday.

“It’s been like, two months of keeping it quiet, which is definitely difficult. I don’t wanna hide it anymore ‘cause it’s hard to always keep in,” Isabella said onGMA.“I hope to just kind of be a voice, and be [someone] who maybe [those who] are going through chemotherapy or radiation can look at.”
