However, brain tumor symptoms usually surface only when the tumor swells abnormally, thus damaging the surrounding tissue.Symptoms can also arise due to formation of hydrocephalus where the flow of cerebrospinal fluid is blocked.rain tumor can be described as an abnormal and uncontrolled division of cells resulting in the formation of intracranial tumors in the brain or other parts such as cranial nerves, skull, pituitary gland, pineal gland and cranial nerves.
