Isabella Strahan, the 19-year-old daughter of "Good Morning America" co-anchor Michael Strahan, has commenced chemotherapy treatment for a medulloblastoma, a type of malignant brain tumor. Michael Strahan shared the update on his daughter's journey, mentioning she had a recent setback involving hospitalization due to a fever. Isabella began experiencing headaches in late October while starting her freshman year at the University of Southern California, leading to the diagnosis. The courageous young lady underwent emergency surgery, followed by radiation treatment, and has now started chemotherapy at Duke University Hospital. Isabella narrates her journey on her YouTube channel, detailing the side effects she has encountered during treatment. The supportive response from both known and unknown individuals has been a source of strength for both Isabella and her father, who revealed the diagnosis in a public interview on "GMA." With approximately 500 children diagnosed with medulloblastoma each year, Isabella's bravery and the support she has garnered reflect the resilience within her and those around her.
