Michael Strahan’s daughter Isabella reacts to fan not knowing if she’s alive as she battles brain cancer

Michael Strahan’s daughter, Isabella, has no time for haters. The 19-year-old, who is battling brain cancer, had the best response when asked if she’s still alive via social media.

In a new video, Isabella danced to Sexyy Red’s “Get It Sexyy” while wearing gray sweatpants and a sweatshirt after someone commented “are you still alive.”

“Better than ever,” one person wrote, to which Isabella replied, “Not going anywhere.”

“Thanks for the update … I was worried,” a second follower wrote.

Isabella replied: “Me too.”

The University of Southern California student and her famous dad revealed her diagnosis during an episode of “Good Morning America” in January. She was diagnosed with a malignant brain tumor known as a medulloblastoma in October and stayed in the hospital for “three or four days,” because she’d been “getting a lot of fevers” after her first chemo treatment.

During her stay, she underwent her first blood transfusion and an MRI of her eyes. She celebrated her last radiation treatment in January.

“It’s been rough. It’s been challenging. It’s been very hard. But I know time will heal and things will get back to — I can’t really say normal because there’s not really a normal now in my life,” she said at the time.

The former athlete, 52, chimed in: “It is tough to see her go through it, but I know she’s a tough young lady, and she’s going to make it through it.”

Earlier this month, Isabella revealed she experienced a setback and had to undergo a third brain surgery.

“It’s not as bad as the first time, but I’m really in pain. They do give me pain medicine … they don’t work that well on me. So I’m in a lot of pain,” she said in a YouTube vlog about the procedure that she received after developing a fever. “My head really, really hurts right now. Not gonna lie, I’ve been crying a lot. I’m in a lot of pain. It’s not as bad as last time … my face isn’t as puffy, but it literally hurts to do anything.”

Isabella has been documenting her journey in her YouTube series.

“GMA” co-host Strahan shares twins Isabella and Sophia with his second wife, Jean Muggli. He’s also dad to daughter Tanita, 32, and son Michael Jr., 29, with his first wife, Wanda Hutchins.
