Nothing if it is not caught in time and a brain tumor is very deceptive. Usually they are attacked by an surgery radiation and chemotherapy in traditional medicine. Surgery is usually tried first. There is a chance that it might not be malignant.
If it is, then doctors throw the whole medicine chest at it. Alternate medicine usually is not anyone's first choice because brain tumors grow quickly and metastasize quite often, usually to the spinal chord. The cancer tends to be more local. Metastasize means that the Cancer shows up somewhere else. It doesn't always happen, but if you come up with the symptoms you'd best go to a doctor and let him/her diagnose it as quickly as possible.
