Michael Strahan's daughter is sharing the emotional moment she finished radiation treatments for her malignant brain tumor. Isabella Strahan, 19, revealed new insight into her health journey in a new KZfaq vlog on Jan. 16, months after undergoing emergency surgery in October to remove a medulloblastoma in her cerebellum. In the video, Isabella smiles through tears as she celebrates her final day of radiation with her doctors, nurses and family cheering her on! After her last treatment, Michael and her twin sister, Sophia, took her out to eat her favorite food - pad Thai! Isabella's latest update comes after she and her father sat down for an interview with "Good Morning America's" Robin Roberts that aired on Jan. 11 to discuss Isabella's diagnosis. Medulloblastoma is relatively common, with an estimated 500 children diagnosed with it each year, though Michael noted that the condition is rare for a late teen.
