Brain tumor or intracranial neoplasm occurs when abnormal cells form within the brain. There are two main types of tumors: malignant or cancer
ous tumors and benign tumors. Cancerous tumors can be divided into primary tumors that start within the brain, and secondary tumors that have spread from somewhere else, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the part of the brain involved.
Tumors depend on their size, type, and location. The most common symptoms of brain tumors include headaches; numbness or tingling in the arms or legs; seizures, memory problems; mood and personality changes; balance and walking problems; nausea and vomiting; changes in speech, vision, or hearing.
