Understanding Glioblastoma
Glioblastomas are aggressive tumors that form in the brain. They are the most common and deadliest type of malignant brain tumors in adults. Glioblastomas belong to a category of tumors known as gliomas, which originate from the glial cells that support and nourish the neurons in the brain. These tumors grow rapidly and infiltrate the surrounding brain tissue, making them difficult to remove completely through surgery.
The symptoms of glioblastoma can vary depending on the location and size of the tumor, but they often include:
- Headaches
- Seizures
- Weakness or numbness in the limbs
- Cognitive difficulties
- Personality changes
- Vision or speech problems
Due to their aggressive nature, glioblastomas require prompt and comprehensive treatment. Treatment options for glioblastoma may include:
- Surgery: The primary goal of surgery is to remove as much of the tumor as possible without damaging critical brain structures. However, complete removal is often not feasible due to the tumor’s invasive nature.
- Radiation therapy: This treatment uses high-energy radiation to target and destroy cancer cells. It is commonly used after surgery to kill any remaining tumor cells and delay tumor regrowth.
- Chemotherapy: Anti-cancer drugs can be administered orally or intravenously to destroy tumor cells or slow their growth. Chemotherapy is often combined with radiation therapy.
- Targeted therapy: This approach utilizes drugs that specifically target certain molecules or genetic mutations found in glioblastoma cells. Targeted therapies aim to disrupt the signaling pathways involved in tumor growth and survival.
The prognosis for glioblastoma is generally poor, with a median survival of around 15 months. However, advancements in research and treatment have led to improvements in survival rates for some patients.
