The type of brain tumor Isabella Strahan is battling, medulloblastoma, accounts for about 20% of all childhood brain tumors, according to estimates published in the Journal of Clinical Neuroscience. About 500 children are diagnosed with medulloblastoma each year.

Michael Strahan said that both he and Isabella have appreciated all the support they have received, both from friends and family as well as strangers. The pair shared Isabella Strahan's diagnosis publicly in an interview with Robin Roberts that aired in January on \"GMA.\"

\"I think, for her, so many people have reached out and said, 'I'm glad you're doing this,' 'Thank you for doing this,' 'This has really helped us,' and all that support that she is getting from people she doesn't know, on top of people that she does know, has kept her in a very positive space,\" Michael Strahan said. \"So thank you to everybody.\"
