Brain tumors are abnormal cell growths in the brain that can be caused by genetic defects, environmental exposure, or random mutations. Symptoms include neurological irregularities and can lead to permanent damage if left untreated. Medical imaging and tissue samples can confirm the presence of a tumor, and treatment may include surgery, chemotherapy, and radiation.
A brain tumor is an area of abnormal cell growth in the brain. These tumors are also called malignancies, and there are a number of types of brain tumors that are classified according to the region in which they appear and their size. Many cancers are malignant, which means they require some form of medical treatment. It is important to seek treatment for neurological irregularities at an early stage, as brain tumors and other neurological conditions will only get worse if they are not addressed.
Tumors are caused by uncontrolled cell division, which causes a swelling to appear. Some cancers are caused by genetic defects that 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 wrong for a tumor to form, as this cell will duplicate without stopping, causing a tumor to emerge. In the confined spaces of the skull, this can become a serious problem very quickly.
The brain itself can develop a tumor, as can cranial nerves and glands in the skull. If a malignant tumor is present in other parts of the body, it can also metastasize to the brain, causing the development of a neoplasm. Once the tumor becomes large enough, symptoms will begin to appear, leading a doctor to recommend medical tests that can be used to diagnose and identify the tumor.
Neurological symptoms such as dizziness, balance difficulties, blurred vision, personality changes, confusion, memory loss, lack of muscle control and slurred speech often characterize brain tumors. In severe cases, seizures and other dangerous symptoms can develop. These symptoms are caused by the pressure exerted on the brain by the tumor. If the tumor is allowed to grow particularly large, it can block blood supply to the region of the brain in which it is located, causing cell death and permanent damage.
Medical imaging studies such as MRIs can be used to identify the presence of a tumor. However, the tumor can only be confirmed by examining a tissue sample from the brain. Once a brain tumor is identified and classified, a doctor can discuss treatment approaches and develop a treatment plan. Excision of the tumor is often recommended, unless the tumor is in an inoperable location, and the use of chemotherapy, radiation, and other techniques may be used in an attempt to kill the tumor and prevent a recurrence.
