A brain benign neoplasm, also known as a benign brain tumor, is a non-cancerous growth that develops within the brain or its surrounding structures. A neoplasm refers to an abnormal mass or lump formed by the uncontrolled growth of cells. Unlike malignant (cancerous) tumors, benign neoplasms do not invade nearby tissues or spread to other parts of the body.
Brain benign neoplasms can arise from different types of brain cells, including the cells that form the protective covering of the brain (meninges), the cells that support nerve cells (glial cells), or the nerve cells themselves. These tumors may present in various shapes, sizes, and locations within the brain.
Although brain benign neoplasms are not cancerous, they can still cause health problems if they press against or interfere with surrounding brain tissue or other vital structures. Symptoms can vary depending on the location and size of the tumor and may include persistent headaches, seizures, cognitive or speech difficulties, weakness or numbness in the limbs, visual disturbances, or changes in behavior.
Diagnosis of a brain benign neoplasm typically involves a combination of imaging tests such as MRIs or CT scans, along with a biopsy to verify the benign nature of the tumor. Treatment options may include observation, surgical removal of the tumor, radiation therapy, or in some cases, targeted drug therapy.
Regular monitoring is usually required to ensure the tumor remains benign or to detect any potential changes over time, as rare cases of benign tumors transforming into malignant tumors have been reported.
