Low Grade Astrocytoma in Adults

Adult astrocytomas are a common form of cancer that originate in star-shaped cells inside the brain. Low-grade versions of this cancer typically exhibit slow growth or complete lack of growth over extended periods of time.

Types

• There are three primary forms of low-grade astrocytoma: pleomorphic xanthoastrocytomas, pilocytic astrocytomas and diffuse astrocytomas, according to the American Brain Tumor Association. While the first two forms typically appear in children, diffuse astrocytomas most commonly appear in young adults and may also appear in seniors.

Diffuse Astrocytomas

• Diffuse astrocytomas frequently grow into surrounding healthy brain tissue, notes the American Brain Tumor Association. They most commonly affect the cerebral hemispheres, which contain functions related to higher-level thinking.

Symptoms

• The American Brain Tumor Association cites potential symptoms of diffuse astrocytomas that include headaches, seizures and weakness limited to one side of the body.

Treatments

• Potential treatment options for adult low-grade astrocytomas include long-term observation and monitoring of destructive changes, surgery and radiation therapy, according to the Mayo Clinic.

Considerations

• Doctors may not be able to surgically remove low-grade astrocytomas that develop in areas of the brain containing sensitive functions, notes the Mayo Clinic.
