What is a brain tumor?

0

The brain is a complex organ made up of many different cells and parts. Many types of cancer can form in the brain. The type of brain tumor a person has depends on where it began and the cells it is made of. Doctors call cancer that begins in the brain a primary brain tumor. The way in which the brain tumor grows and affects the different functions of the body is its pathophysiology. Brain tumors usually do not spread, or metastasize, outside of the brain. Instead, they have a special way of growing and moving throughout the brain. Cancer in the brain that has spread from other types of cancer is not considered brain cancer. They are still the same type of cancer as where they started. For instance, lung cancer that has spread to the brain isn’t called brain cancer; it is called metastatic lung cancer.

A 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. The location of a brain tumor influences the type of symptoms that occur. This is because different functions are controlled by different parts of the brain. Brain tumors rarely metastasize (spread) to other parts of the body outside of the central nervous system (CNS). The CNS includes the brain and spinal cord. Some tumor types are more common in children than in adults. When childhood brain tumors occur in adults, they often occur in a different part of the brain than in children. Although most primary tumors attack member of both sexes with equal freq

Adult brain tumors are diseases in which cancer (malignant) cells begin to grow in the tissues of the brain. The brain controls memory and learning, senses (hearing, sight, smell, taste, and touch), and emotion. It also controls other parts of the body, including muscles, organs, and blood vessels. Tumors that start in the brain are called primary brain tumors. Adult brain tumor is diagnosed and removed in surgery. If a brain tumor is suspected, a biopsy is done by removing part of the skull and using a needle to remove a sample of the brain tissue. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor will remove as much tumor as safely possible during the same surgery. An MRI may then be done to determine if any cancer cells remain after surgery. Tests are also done to find out the grade of the tumor.

A brain tumor is an area of abnormal cell growth in the brain. Brain tumors are also called neoplasms, and there are a number of types of brain tumors which are classified by the region in which they appear and their size. Many brain tumors are malignant, which means that they require some form of medical attention. It important to seek treatment for neurological irregularities at an early stage, as brain tumors and other neurological conditions will only grow worse if they are not addressed. Tumors are caused by uncontrolled cell division, which causes a swelling to appear. Some tumors are caused by genetic defects which lead to tumor formation, while others develop in response to environmental exposure, or as a result of a random mutation acquired during cell duplication at the site. All it takes is one cell gone awry for a tumor to form, as this cell will duplicate itself without stopping, causing a tumor to emerge.
