Is a pituitary tumor a brain tumor?
Pituitary Society - Public Site - Information about the pitu...The pituitary gland is NOT in the brain and pituitary tissue is different from brain tissue. Since the pituitary gland is located at the base of the brain and is connected to the brain by a thin stalk, there is often confusion, particularly by insurance companies, about the classification of a pituitary tumor. A pituitary tumor is NOT a brain tumor.
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
What is a pituitary Tumor?
Pituitary Network Association - FAQA pituitary tumor is an abnormal growth of pituitary cells. Pituitary tumors can either be nonfunctional (that is they do not secrete hormones) or produce specific hormones, such as prolactin (causing infertility, decreased libido, and osteoporosis), growth hormone (causing acromegaly), ACTH (causing Cushing's), TSH (causing hypothyroidism), or be nonfunctional (that is they do not produce hormones).
Related QuestionsWhat are the symptoms of a pituitary tumor?
This depends on the type of tumor and the size of the tumor. A large tumor may cause loss of vision, particularly peripheral vision, if it compresses the optic chiasm (where the optic [eye] nerves converge). Headache may also occur; the type of headache varies from patient to patient. Headache may occur with a large or a small tumor.
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 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.
Related QuestionsHow is a brain tumor treated?
Brain Tumor FAQThe standard treatments for brain tumors are surgery, radiation therapy, and chemotherapy. In general, radiation and chemotherapy treatments are used as secondary or adjuvant treatments for tumors that cannot be managed using only surgery. However, radiation and chemotherapy may be used without surgery if the tumor is inoperable.

What is the difference between a primary brain tumor and a metastatic (secondary) brain tumor?
Brain Tumor FAQPrimary brain tumors originate in the brain itself. Primary brain tumors do not spread from the brain to other parts of the body, except in rare cases. Pathologists classify primary brain tumors into two groups: glial tumors (gliomas), and non-glial tumors. Gliomas are composed of glial cells, which include astrocytes, oligodendrocytes, ependymal cells, Schwann cells, microglia, and satellite cells.
Related QuestionsWhat will happen to a patient with a brain tumor?
Brain Tumor FAQTo a large extent, what happens to you depends on the type of tumor you have, its location, the area of the brain involved and the forms of therapy you’ll have. But each patient is different, and these are not the only factors to be considered. For patients and their families, the brain tumor experience is a journey into an unknown land filled with uncertainty.
Related QuestionsWhat is the best treatment for a pituitary tumor?
Prolactin-producing tumors are most successfully treated with medical therapy (pills). In over 90% of patients, medical therapy reduces tumor size and blood prolactin levels. In approximately 8-10% of patients, medical treatment is not completely effective and surgery may be necessary.
Related QuestionsWhat causes a pituitary tumor to develop?
Pituitary Society - Public Site - Information about the pitu...Pituitary tumors are common. In autopsy studies of patients who did not have known pituitary disease, as many as 26% had a small tumor (adenoma) in the gland. Molecular biology studies have shown that a change in the DNA of pituitary cells can cause unregulated growth of a particular cell type resulting in a pituitary tumor, called an adenoma. There are no known environmental causes. Very uncommonly, pituitary tumors may be inherited.
Related QuestionsIs a pituitary tumor cancer?
Pituitary Society - Public Site - Information about the pitu...No, in over 99% of patients, this is NOT a cancer; it is benign. Although the tumor is benign, it can cause problems because of its size, because it causes the normal pituitary gland to become underactive (hypopituitarism) or because of excessive hormone production by the tumor.
