‘GMA’ Host Michael Strahan’s Daughter Reveals Brain Tumor Diagnosis

Michael Strahan came on his own show to share that his daughter was recently diagnosed with a rare brain cancer … and it explains why he’d taken off so much time from both of his TV jobs back in the fall.

The ‘GMA’ host sat for a segment on the ABC program Thursday opposite his coworker Robin Roberts — where he and his 19-year-old, Isabella, revealed she’s been receiving treatment lately for a malignant tumor doctors found in her brain in October.

The cancer is known as medulloblastoma, and in the package they aired … Roberts goes into detail about the size of the tumor that was discovered by doctors — noting it was about as big as a golf ball and lodged toward the base of her skull.

Once they discovered the tumor, Isabella underwent emergency surgery at Cedars-Sinai in L.A. … which is here Michael’s daughter was attending college at USC.

Once her father caught wind of everything, he says he booked it to the West Coast — Mike’s normally working in NYC — and he was by Isabella’s side for a good long while … which now explains his absence from ‘GMA’ and Fox NFL Sunday around that time.

The procedure to remove the mass appears to have been a success — with the operation happening right around her 19th birthday — and her recovery was long and arduous.

Now, though … Isabella says she’s doing much better as she continues to receive treatment — including radiation, which has caused her to lose her hair. In February, Michael says she’ll begin chemo as well. Of course, the whole journey has been stressful on the family.
