Overview of Anaplastic Astrocytoma
Anaplastic astrocytoma is a serious brain cancer. It mainly affects the brain’s glial cells. It’s important to know about this condition to understand its effects.
What is Anaplastic Astrocytoma?
Anaplastic astrocytoma is a grade III tumor, as classified by the World Health Organization (WHO). It’s a fast-growing cancer that comes from lower-grade astrocytomas. The anaplastic tumor definition says these tumors have abnormal cells, grow fast, and spread to nearby brain areas. This shows it’s a serious condition needing quick and strong treatment.
Prevalence and Demographics
Anaplastic astrocytoma is a rare brain cancer, making up about 2-3% of all primary brain tumors. In the U.S., it’s thought to start in around 650 new people each year. It usually happens in adults between 30 and 50, but can also affect kids. This shows why it’s important to know about it and fund research across all ages.
How It Differs from Other Brain Tumors
Anaplastic Astrocytoma: Symptoms & Treatment Options Anaplastic astrocytoma is between low-grade and very aggressive glioblastomas in terms of danger.
