This year’s celebrations looked very different from last year’s birthday for Isabella.

The day before her 19th birthday, Isabella was hospitalized and had to undergo emergency surgery to remove a large malignant tumor from her cerebellum.

The USC student ended up spending her birthday bedridden during her recovery and her friends and family decorated her hospital room with birthday decorations like balloons, flowers and stuffed animals.

Isabella addressed the stark difference between the two birthdays by sharing photos from her difficult hospital stay on her Instagram in honor of her big milestone birthday this year.

“365 days since my life changed tremendously. Thankful for the progress I’ve made,” she said.

Doctors discovered she had a “fast-growing, 4-centimeter tumor” after she had experienced symptoms like headaches and nausea.

Following the procedure to remove the malignant brain tumor known as a medulloblastoma, she underwent radiation therapy and 30 days of rehabilitation.

In June, Michael announced that his daughter had completed her chemotherapy.
