Anatomy and Classification of Astrocytoma
Astrocytomas come from astrocytes, star-shaped cells in the brain. They are part of gliomas. Understanding how astrocytes work helps us see why astrocytomas grow and spread.
Astrocytes and Their Role in the Brain
Astrocytes help keep the brain healthy. They support nerve cells, heal brain injuries, and control the brain’s environment. When these helper cells turn into cancer, astrocytomas can form. They grow out of control, causing problems.
Classification of Astrocytomas
Astrocytomas are grouped into different levels of seriousness, from one to four. This grading is done by the WHO (World Health Organization).
- Grade I: Pilocytic Astrocytoma – These are usually not aggressive and grow slowly.
- Grade II: Diffuse Astrocytoma – They grow slowly too but may come back after treatment.
- Grade III: Anaplastic Astrocytoma – They are more aggressive and look more abnormal.
- Grade IV: Glioblastoma – This is the most serious type, grows fast, and has a poor outlook.
Knowing the grade of an astrocytoma helps doctors in planning the right treatment. Each level needs a special way of care. Treating these tumors is a complex task.
