My son has a grade 3 anaplastic astrocytoma. He had surgery at Sloan Kettering in January which removed the malignant tumor. He has refused any further treatment. My question is how long does he have before he becomes symptomatic again. He lives by himself in another state and I am concerned he will become symtomatic again and we won t know.

Summarized question: How frequent does anaplastic astrocytoma reoccur?
