C71: Malignant neoplasm of brain

Malignant neoplasm of the brain, commonly known as brain cancer, involves the uncontrolled growth of abnormal cells in the brain. The condition is characterized by a diverse group of tumors that can originate either in the brain (primary cancer) or spread to the brain from another part of the body (secondary or metastatic cancer). Brain cancer can affect people of all ages and does not discriminate based on gender or ethnicity. Common symptoms of brain cancer can include headaches, seizures, changes in personality or behavior, balance problems, vision disturbances, or difficulty speaking. The condition's progression can vary, with some cases developing rapidly and others growing slowly over time. The underlying causes of malignant neoplasms of the brain are not entirely understood, but factors such as exposure to radiation, inherited genetic mutations, and a history of certain types of cancer can increase the risk of developing the condition. It is essential to know that having one or more risk factors does not guarantee that an individual will develop brain cancer.
