Glenn Campbell, a BBC journalist, documents his experience with an aggressive brain tumour in a new film titled ‘My Brain Tumour And Me’. Initially diagnosed with glioblastoma after experiencing a seizure following a bicycle crash, he later discovered he has a more treatable form, oligodendroglioma. Despite significant challenges, including seizures and hospitalizations, Campbell remains optimistic, has returned to mountain climbing, and is raising awareness for brain cancer. He emphasizes the importance of support from family, friends, and the medical community during his journey.
