As a member of the New York Giants for 15 seasons, Michael Strahan played with a relentless style that allowed to persevere through all kinds of adversity.

Now, Strahan’s daughter Isabella is embracing that same resilient mindset in the face of a major health challenge. 

Isabella, the 19-year-old daughter of the Pro Football Hall of Famer and Good Morning America co-host, is set to undergo further treatment for medulloblastoma. This is a malignant type of brain cancer, according to Cancer Therapy Advisor, a Haymarket Media publication.

This disease accounts for 20% of all childhood brain cancers and most commonly presents in children between the ages of five and nine. The five-year survival rate for medulloblastoma is 72%, according to data from the National Cancer Institute, though many factors can affect a prognosis. 

She was diagnosed with medulloblastoma in the fall after experiencing increasingly severe headaches and underwent an MRI to see what was causing them. In late October, she underwent surgery to have the mass removed at Cedars-Sinai Medical Center in Los Angeles.

Following a month of physical rehabilitation, she received 30 sessions of radiation treatment over six weeks.

Sitting beside her dad, Isabella went public with her patient journey Thursday morning in an interview with his Good Morning America colleague Robin Roberts, who has her own well-documented history with cancer. Roberts previously underwent treatment for breast cancer and then a rare blood disorder that required a bone marrow transplant in 2012.

In the interview, Isabella said it has been hard keeping her battle quiet over the past few months and wanted to bring attention to this form of brain cancer.

“I don’t want to hide it anymore, because it’s hard to keep it in,” she said. “I want to be a voice and someone that people who are going through chemotherapy or radiation can look at and find something interesting about their day.”

To that end, Isabella launched a YouTube series in partnership with Duke Children’s Hospital to document her patient journey as she prepares for chemotherapy treatment next month. All proceeds from the series will benefit the Preston Robert Tisch Brain Tumor Center at Duke University Medical Center, where she is set to receive her care.

In the first video of the series – which is seven minutes long – Isabella brings viewers up to speed on how her care journey began and outlines her hopes of eventually getting back to life as a college student.

“I’m trying to think positively,” she said at the end of the video. “For anyone else going through this: think positively and things will get better.”
