Michael Strahan's Daughter Sophia Praises 'Strong' Twin Sister Isabella After Her Brain Tumor Diagnosis: 'You Inspire Me'

“The last few months have been so much harder than we could have ever imagined,” Sophia, 19, said after her twin sister Isabella had emergency surgery to remove a brain tumor

Michael Strahan’s daughter Isabella has been undergoing treatment for a malignant brain tumor known as medulloblastoma since October 2023. Medulloblastoma is a malignant tumor that is located on the part of the brain that controls coordination and movement.

On Thursday, shortly after the 19-year-old went public with her diagnosis, her twin sister Sophia posted a series of photos of the pair on Instagram and praised how strong Isabella has been throughout her difficult health battle.

“I’m so lucky to have the most amazing sister and best friend in the world,” Sophia captioned the post. “The last few months have been so much harder than we could have ever imagined, but it’s made me realize just how strong you are. You inspire me and I’m so proud of you. Us forever 💞”

“Best sister ❤️” Isabella replied.

Isabella first shared her diagnosis during a segment on Good Morning America alongside 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 told Robin 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.

Following her surgery, Isabella underwent several rounds of radiation treatment, as well as a month of rehabilitation. "I got to ring the bell yesterday," she told cancer survivor Roberts, 63. "It was great. It was very exciting because it's been a long 30 sessions, six weeks."

Isabella said Sophia was by her side the whole time, helping her learn to walk again. She has now started documenting her journey in a new YouTube series to benefit Duke Children's Hospital & Health Center.

"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 on GMA. "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."
