The signs and symptoms and the MRI characteristics usually determine the diagnosis of the brain lesion and the urgency of the surgery
Some like meningioma
donot need urgent surgery, but if it is suspicious of glioblastoma, then urgent surgery may be required. If a neurosurgeon
has advised for the same, better to go for it.
