How does the Gamma Knife procedure compare to neurosurgery for a brain tumor?
Gamma Knife of Spokane - Frequently Asked QuestionsBecause Gamma Knife radiosurgery requires no incisions and no general anesthesia, the risks of complications, infection or other side effects are greatly reduced if not eliminated altogether. As an outpatient procedure for trigeminal neuralgia, the patient can in most cases, return home by dinner the same day of surgery and resume normal activity. For many tumors and tremors, the actual procedure takes less than 3-4 hours from the time the head frame is affixed to 'frame off'.
Related QuestionsHow does the Gamma Knife? work?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...The Gamma Knife Perfexion? precisely focuses 192 beams of gamma radiation on a specific target area of the brain, with each beam originating from a slightly different point. Highly sophisticated computer software is used to determine the size, location and shape of the area to be treated. Only at the point where all 192 beams cross is enough radiation delivered to affect the diseased tissue, while sparing surrounding tissue.

Related QuestionsWhat is a brain tumor?
Johns Hopkins Surgical Neuropathology: Frequently Asked Ques...The meaning of the word tumor is a "lump" or a "swelling", and in medical language it is used to indicate an abnormal, uncontrolled growth in any part of the body. You may think of it as a group of cells which rapidly divide and do not recognize any rule or limit. The brain tumors are similar to the tumors of other organs. However, since the brain is the center of many critical functions, tumors arising in this organ have serious outcomes.
Related QuestionsPediatric FAQA brain tumor is an abnormal mass of tissue in which some cells grow and multiply uncontrollably, apparently unregulated by the mechanisms that control normal cells. The growth of a tumor takes up space within the skull and interferes with normal brain activity. A tumor can cause damage by increasing pressure in the brain, by shifting the brain or pushing against the skull, and by invading and damaging nerves and healthy brain tissue.Related Questions
Is The Gamma Knife Procedure Safe?
Gamma Knife CenterGamma Knife Radiosurgery is unique because no surgical incision is performed to "expose" the lesion. Consequently, the risk of surgical complication is greatly reduced. Patients are routinely administered a mild sedative, eliminating the side effects of general anesthesia.
Related QuestionsWho can be treated with the Gamma Knife?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...This noninvasive technology treats patients with abnormalities that are located within the brain or that are too close to delicate structures and blood vessels (though it is most effective on targets less than four centimeters in size). Almost a third of all the patients treated with the Gamma Knife since 1968 have sought relief from blood vessel problems (i.e. AVMs). Nearly two-thirds were treated for brain tumors, including cancer, glial tumors and rarer types of tumors.
Related QuestionsWhy is it called the Gamma Knife if there are no incisions made?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...The individual beams of gamma radiation are not strong enough to damage any tissue as they travel through the skull to the treatment site. At the site, the beams join together pecisely to act in the same way a surgical "knife" would to treat the abnormality.
Related QuestionsHow is a brain tumor diagnosed?
Brain Cancer FAQThe doctor does a complete physical exam with special attention to neurological examination. This includes checks for alertness, muscle strength, coordination, reflexes and response to pain. The doctor also examines the eyes for swelling caused by a tumor pressing on the nerve that connects the eye and the brain. The doctor may request a CT (or CAT) scan or an MRI. A CT scan is a series of detailed pictures of the brain. The pictures are created by a computer linked to an X-ray machine.
Related QuestionsIs a benign brain tumor safe?
Brain Tumor Guide: FAQThere are two meanings of the word benign in reference to brain tumors. Just as brain tumors are not cancerous, brain tumors are benign because they do not spread outside the brain. However, growths in the brain are dangerous because of the importance of the brain and the limited amount of space inside the skull. Therefore, this meaning of the word benign is meaningless and misleading when applied to brain tumors. Brain tumors are often divided between benign and malignant tumors based on grade.
Related QuestionsHow is a brain tumor recognized?
Johns Hopkins Surgical Neuropathology: Frequently Asked Ques...Many brain tumors may create complaints which force the patient to seek medical help. However, today more and more tumors are being recognized before they create complaints with the help of advanced radiological studies. These studies sometimes are performed for other reasons, and coincidentally lead to discovery of tumors. Even though the physician may find the effects of a brain tumor in the body, he/she can not feel or see them during a routine physical examination.
Related QuestionsHow is a definitive diagnosis of a brain tumor made?
Johns Hopkins Surgical Neuropathology: Frequently Asked Ques...The most accurate, and sometimes the only way to accurately diagnose a brain tumor requires a biopsy. The surgeon performs the biopsy and the pathologist makes the final diagnosis, and can tell whether the tumor appears benign or malignant.
Related QuestionsWhat is a benign brain tumor?
Johns Hopkins Surgical Neuropathology: Frequently Asked Ques...Benign probably is derived from the Latin word benigenus which means "a good kind" (bene= well, genus= born of, kind). In theory all benign tumors behave well and do not pose serious danger to the patient. Benign tumors are usually easily separated from normal tissues and therefore they can be removed surgically. However, tumors do not read books, so they are not aware of this sharp definition.
Related QuestionsWhat is a malignant brain tumor?
Johns Hopkins Surgical Neuropathology: Frequently Asked Ques...This word is derived from the Latin malignus which meant evil disposed, and is used as the opposite of benign. A malignant brain tumor is life-threatening. Malignant brain tumors possess certain chemicals which enable them to infiltrate into other tissues and spread into other parts of the body. Malignant tumors are almost impossible to remove totally by surgery, unless they are caught early in their course.
Related QuestionsWhat is the difference between a benign brain tumor and a malignant (cancerous) brain tumor?
Pediatric FAQBenign brain tumors are slow-growing tumors that can be removed or destroyed if in an accessible location. Malignant tumors (brain cancer) are rapidly growing tumors that invade or infiltrate and destroy normal brain tissue. No one is certain why, but some benign brain tumors may change over time to become malignant. Tumors are graded to indicate how quickly they are growing. Most medical institutions use the World Health Organization (WHO) classification system to identify brain tumors.
Related QuestionsWhat does it mean when a brain tumor is in remission?
Brain Tumor FAQWhen a tumor is in remission or is stable, it means the tumor cells have entered a phase in which they generally have stopped growing or multiplying. This may or may not mean that these tumor cells will never grow again. In some cases, the tumor has actually been destroyed and the area it occupied in the brain is composed only of dead tissue, called necrosis.

Related QuestionsMy doctor says a brain tumor is not cancer. Is that true?
Brain Tumor Guide: FAQTechnically, yes. A tumor is cancerous if it will spread, or metastasize, beyond it's original site to other parts of the body. Primary brain tumors rarely, if ever, spread outside the brain, so they are not technically cancer. However, psychologically and practically, brain tumors are a lot like cancerous tumors.
Related QuestionsWhat are the symptoms of a brain tumor?
Vanderbilt Brain Tumor Center - Frequently Asked QuestionsBrain tumors can sometimes cause seizures. Often a seizure is the first symptom of a brain tumor. Because brain tumors can occur anywhere within the brain ? the symptoms depend on the location of the tumor. For example, a tumor that pushes against the optic or visual nerve may cause loss of vision. A tumor growing in the language centers of the brain may lead to trouble with speaking or understanding language.
Related QuestionsBrain Tumor FAQThe most common symptoms include headaches, which can be most severe in the morning; nausea or vomiting, which can be most severe in the morning; seizures or convulsions; difficulty thinking, speaking, or finding words; personality changes; weakness or paralysis in one part or one side of the body; loss of balance; vision changes; confusion and disorientation; and memory loss. Different parts of the brain control different functions, so symptoms will vary depending on the tumor’s location.Related Questions
Is a brain tumor cancer?
Brain Tumor FAQSome brain tumors are cancerous and some are not. Malignant tumors are considered cancer. Two of the most common forms of brain cancer are metastatic brain tumors (brain metastases) and glioblastoma multiforme (GBM). Brain cancer cells mutate and lose their normal form or structure. This is called anaplasia. The degree of anaplasia helps to forecast a tumor's growth potential. The most rapidly growing tumors have the highest degree of anaplasia. Benign tumors are not considered cancer.
