Astrocytomae are tumors that come from astroglial cells. These cells support brain neurons. They are common brain tumors that can hurt brain functions. The type and grade of astrocytoma affect treatment and how well someone will do.
Types of Astrocytoma
The World Health Organization groups astrocytomae by how bad they are:
- Pilocytic astrocytoma (Grade I): Usually not cancerous and grows slowly
- Diffuse astrocytoma (Grade II): Spreads more but is not very aggressive
- Anaplastic astrocytoma (Grade III): Very cancerous and aggressive
- Glioblastoma (Grade IV): The most cancerous and aggressive type
Symptoms and Signs
Astrocytoma symptoms depend on the tumor’s size, where it is, and how fast it grows. Common signs include:
- Headaches
- Seizures
- Cognitive or motor deficits
These symptoms happen when the tumor presses on brain parts. Seeing a doctor early can help with treatment.
