A GBM, or glioblastoma multiforme, is a very aggressive type of cancer that occurs in the brain. It’s known for its rapid growth and tendency to spread within the brain tissue, making it difficult to treat effectively. GBMs are grade IV tumours with the highest grade and indicate a high degree of malignancy. Symptoms can vary widely depending on the tumour’s location in the brain, including headaches, seizures, cognitive changes, and weakness on one side of the body. Treatment typically involves a combination of surgery to remove as much of the tumour as possible, followed by radiation therapy and chemotherapy to target the remaining cancer cells. Despite advancements in treatment, GBMs are challenging to combat, focusing on extending life and improving the quality of life for those affected.
