Michael Strahan is speaking candidly about his daughter’s fight against cancer.

The former professional athlete and current daytime TV host recently spoke with People in an interview released on Wednesday, highlighting the incredible resilience shown by Isabella, who is now 20 years old, during her challenging journey.

“She looked frail, fatigued, and bald, experiencing everything a parent hates to witness,” Strahan recounted. Isabella was diagnosed with medulloblastoma in 2023 and began her treatment just after turning 19.

This type of cancer originates in the lower rear section of the brain and is typically seen in young children, as explained by the Mayo Clinic.

“Her spirit was unwavering,” Strahan shared with People. “One of the hardest things to hear from her was, ‘Dad, I’ll do whatever it takes. I want to live.'”

“I knew she would not give up,” he added. “She was determined to fight—and she did.”

After multiple rounds of radiation, chemotherapy, and various surgeries, Isabella is now free of cancer.

“They put everything aside,” she recalled, discussing how her family responded to her diagnosis. She first experienced symptoms like nausea, dizziness, and headaches while in college, confiding in her twin sister, Sophia, who eventually informed the rest of the family.

“My mom would stay overnight with me at the hospital,” Isabella said. Her mother, Jean Muggli, was married to Strahan from 1999 to 2006, and together they raised the twins.

“Isabella’s inner strength and tenacity have always been remarkable, just as they were when she was younger,” Muggli expressed to People. “The grace with which she managed each day was truly inspiring.”

During her recovery—from the surgery to remove the tumor and the relearning of essential skills like eating, walking, and speaking—Isabella documented her experience through a series of YouTube vlogs aimed at connecting with other young cancer survivors. The proceeds she earned from these videos were donated to the Preston Robert Tisch Brain Tumor Center at Duke University, where she received treatment.

Now that she is back in college, her health will be closely monitored over the next few months, and then less frequently in subsequent years.

“Her doctors are very confident that she will be okay,” Strahan tells People. “That is the hope we cling to, although we still feel anxious each time. Those nerves won’t fade, but as long as we keep getting good results, we’ll keep fighting.”

ABC, the network broadcasting “Good Morning America,” which Strahan hosts, will air a special on February 5 called “Life Interrupted: Isabella Strahan’s Fight Against Cancer,” chronicling the family’s experience. It will also be available on Hulu and Disney+ the following day.
