Since her diagnosis, which she revealed publicly in January, Isabella Strahan has undergone brain surgery as well as several rounds of radiation treatment.

She began chemotherapy in February and has endured several hospitalizations due to setbacks including fevers.

In her latest vlog, Isabella Strahan spoke about side effects of chemotherapy she has experienced including hair loss, brain fog, physical weakness and fatigue.

She has been sharing her health journey and raising awareness about brain tumors on her YouTube channel, which benefits Duke University's Preston Robert Tisch Brain Tumor Center, where she has been receiving treatment.

Near the end of her latest video, Isabella Strahan breaks down in tears when she is surprised by her twin sister, Sophia, who is a student at Duke University.
