Fans of football and television legend Michael Strahan were saddened this week to learn that his daughter Isabella has been diagnosed with cancer.

According to the New York Post, both father and daughter spoke about the new struggle on Thursday with "Good Morning America" host Robin Roberts.

Tumor found in Isabella's cerebellum

They explained how Isabella underwent an MRI in October of last, after which she was found to have a malignant brain tumor known as a medulloblastoma.

The Mayo Clinic's website states that a medulloblastoma starts in the cerebellum, an area at the back of the brain that is in charge of muscle coordination, balance, and movement. While rare, it is the most common form of brain cancer found in children.

Isabella told Roberts that she "didn’t notice anything was off until probably like October 1," at which point she began to experience headaches, nausea, and difficulty with walking.

The University of Southern California freshman finally notified her family of the symptoms after she started vomiting up blood.

YouTube channel will document cancer battle

Doctors operated on Isabella in late October, and the procedure was followed by six weeks of radiation treatment. She is set to begin undergoing chemotherapy next month.

"I'm feeling good, not too bad. I'm very excited for this whole process to wrap, but you just have to keep living every day through the whole thing," she said.

Isabella has decided to document her treatment on a new YouTube channel, with the first video being uploaded on Thursday.

"With my platform, I hope to just kind of be a voice and be a person who people who maybe are going through something similar, going through chemotherapy or radiation, can look at and just hear and just watch, or find something interesting about their day," she said before adding, "I’m just excited for that."

Michael Strahan thanks supporters

Isabella's father commented on her daughter's decision to share details of the battle, saying, "This is something that is so personal.

"But her idea was, 'I want to share it and I want to help other people,' and that goes into the spirit of who she’s always been," he stressed.
