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 is the difference between primary and metastatic brain tumors?
FAQ, Richmond Brain Tumor Support GroupA tumor that starts growing in the brain is a primary brain tumor. These tumors may spread within the brain, but rarely travel to other sites in the body. Metastatic brain tumors are formed from cancer cells that originate in other parts of the body, and travel to the brain to form tumors. Cancers of the lung, breast, colon and melanoma often spread to the brain.
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 options are there to treat a metastatic tumor in the brain?
Vanderbilt Brain Tumor Center - Frequently Asked QuestionsPatients with a diagnosis of a metastatic brain tumor should be evaluated by a neurosurgical oncologist. Currently, treatment options could include surgery to remove the tumor, radiation therapy or chemotherapy. Focused radiation ? so called radiosurgery ? is becoming an important way to treat patients with brain metastasis.

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 metastatic tumor?
Vanderbilt Brain Tumor Center - Frequently Asked QuestionsA metastatic tumor is a malignant cancer that started in another organ in the body and then separated and moved to another organ such as the brain. The most common brain cancer is metastatic. Up to 30% of patients with a diagnosis of cancer will develop a metastatic tumor. Some cancers have a preference or predilection to move to the brain. These include kidney, lung, skin (melanoma), and breast.
Related QuestionsWhat is the difference between primary and secondary alexithymia?
The primary/secondary classification system was introduced early on by one of the original team of alexithymia researchers: Finally, it is of interest that some patients with severe, life-threatening or debilitating bodily conditions may develop an alexithymic picture in the course of their illness. This is particularly the case with individuals in renal dialysis or intensive care units (Freyberger, in press) and has been termed by one of us (H.F.) 'secondary alexithymia'.
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 primary and secondary brain injury?
Health InformationPrimary brain injury refers to the sudden and profound injury to the brain that is considered to be more or less complete at the time of impact. This occurs at the time of the car accident, gunshot wound, or fall. Secondary brain injury refers to the changes that evolve over a period of time (from hours to days) after the primary brain injury. It includes an entire cascade of cellular, chemical, tissue, or blood vessel changes in the brain that contribute to further destruction of brain tissue.

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.
