Primary malignant brain tumors are abnormal growths that originate in the brain tissue and are characterized by the uncontrolled division and multiplication of cells. These tumors are considered primary as they begin in the brain or its surrounding structures, unlike metastatic tumors that have spread from other areas of the body. Malignant brain tumors are highly aggressive and have the potential to invade nearby healthy brain tissue, leading to various neurological symptoms and impairments.
These tumors are classified as malignant due to their capability to infiltrate, destroy normal brain tissue, and potentially spread to other parts of the central nervous system. The exact cause of primary malignant brain tumors is unknown, although certain genetic and environmental factors have been associated with their development.
Common symptoms of primary malignant brain tumors can include persistent headaches, seizures, gradual loss of neurological function, changes in behavior, impaired vision, and difficulty with speech or movement. Diagnosis typically involves a combination of imaging tests, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, along with a biopsy to determine the type and grade of the tumor.
Treatment for primary malignant brain tumors depends on various factors including size, location, type, and the overall health of the individual. It may involve a combination of surgery, radiation therapy, and chemotherapy. Prognosis for primary malignant brain tumors varies greatly, with survival rates dependent on factors such as the tumor's stage, grade, location, and the individual's response to treatment. Close monitoring and regular follow-up visits with the healthcare team are crucial to manage the condition effectively.
