D33: Benign neoplasm of brain and other parts of central nervous system
Benign neoplasms of the brain and other parts of the central nervous system refer to noncancerous growths that arise from different cells within this system. Even though these neoplasms are not cancerous, they can cause problems due to their location and size. For instance, a benign brain tumor can press on sensitive areas of the brain and disrupt normal functions. Symptoms can vary but often include headaches, seizures, cognitive or personality changes, imbalance, weakness, or numbness in parts of the body. These conditions are typically not a result of infection and are not inherited or transmitted from one person to another. Disease progression can take months or years without causing any noticeable symptoms. Once symptoms appear, however, they frequently become worse over time due to the tumor's growth or associated swelling. The specific cause of these benign neoplasms is unknown, but they might be due to certain genetic factors or previous radiation exposure.
