In brief: Depends on type

The type and grade of the tumor will determine the growth rate.
If the brain tumor is benign, it may grow slowly for months to years before causing symptoms (ie. Meningioma). If the tumor is malignant or aggressive, it will grow rapidly over about 6-12 weeks. Manifestation of symptoms depends on location. If it is adjacent to areas that control movement or speech, the symptoms are seen sooner.
