'Not fun:' Michael Strahan's daughterIsabella, 19, shares health update ahead of chemotherapy

'The longest journey': Isabella chronicles brain cancer battle

Isabella called chemotherapy "the longest journey" and opened up about her health anxiety.

"I think it just stresses me out because so much could go wrong I feel," Isabella said. "Oh no, my heart hurts. That could mean I'm having a heart attack, or, like, my eye is strained. What if my eyes stop working?"

In a separate YouTube vlog earlier this month, Isabella shared the "not fun" part of her health journey before starting chemotherapy for cancer.

"I’m getting my port placed today, which is a device that goes on your chest for administering chemo, getting my blood drawn, all that fun stuff," Isabella said, adding, "I’m not excited."

Isabella shared how doctors placed a chemotherapy port in her chest, which allows the medical team to draw blood and administer treatments without continuous needles. She was joined by her mom, Jean Muggli, and aunt for the treatments and Isabella took a brief break to play a card game during a kidney test wait.

"I would say it's not my fave," she said as she was administered an IV.

"I got an IV put in for this kidney thing… Never fun. Healing from my port surgery… Not fun at all. I now have a wire in my chest. They just put radioactive dye in my body and then I have a blood draw and then an EKG, then I have another blood draw, then I have an MRI," she said of her "busy day" ahead.

Michael Strahan and daughter Isabella, 19, reveal brain tumor diagnosis on 'GMA'

Isabella revealed diagnosis on 'Good Morning America'

During her appearance on “GMA” with her father Michael Strahan and Roberts, it was revealed that Isabella’s twin sister Sophia encouraged her to seek treatment and she later received the diagnosis in October after an MRI scan.

One day before her 19th birthday, she had surgery to remove the tumor, which was slightly larger than a golf ball.

Strahan made headlines during a three week-long absence from his hosting duties at the end of October and early November. An ABC spokesperson told USA TODAY the break was due to "some personal family matters" in a statement at the time. Up until his "GMA" appearance with Isabella, no details were released about his absence.
