Teen diagnosed with aggressive brain tumor after pupil change

A teenager named Joscelyne Kerr, 19, was diagnosed with an aggressive brain tumor after noticing a change in her pupil. Initially thought to be a rare neurological disorder, further scans revealed a tumor on her ocular nerve, which has a poor prognosis. After surgery to remove 90% of the tumor, Joscelyne faced complications but eventually regained her functions. She was later diagnosed with an ultra-rare tumor and given a prognosis of 12 to 18 months, prompting her family to raise funds for a trial drug that may help her. Joscelyne has raised nearly £100,000 for the drug DCVax-L, which shows promise for her condition. She is also advocating for more research into brain tumors, emphasizing the need for better treatment options.
