How common are astrocytomas?
The average annual age-adjusted incidence rate for tumors of neuroepithelial tissue (which includes astrocytomas) is 6.6 per 100,000, according to figures from the Central Brain Tumor Registry of the United States in 2016. Most cases of pilocytic astrocytomas are diagnosed by the age of 20.

What is low grade astrocytoma?

Are astrocytomas hereditary?
Many cases appear to be random events, while researchers suspect that some astrocytomas may be hereditary or linked to chemical exposure in utero. Brain tumors in general, though, develop as a result of rapidly dividing brain cells.
