D37-D48: Neoplasms of uncertain or unknown behaviour
D43: Neoplasm of uncertain or unknown behaviour of brain and central nervous system
Neoplasms of uncertain or unknown behavior of the brain and central nervous system refer to abnormal growths that can be found in the brain or spinal cord, whose benign or malignant nature is not yet determined. These growths, known as neoplasms, can cause a variety of symptoms depending on their size, location, and rate of growth. Common symptoms may include headaches, vertigo, changes in personality or mental functions, seizures, and unexplained nausea or vomiting. Although the causes often remain unknown, they may arise due to genetic mutations, certain environmental factors, or previous exposure to radiation. Neoplasms of uncertain behavior do not necessarily indicate a progression to cancer, but careful monitoring is needed due to the critical areas they affect. The management strategy often depends on the individual's overall health, the location and size of the growth, and associated clinical symptoms.
