Brain tumor

Patent Pending A brain tumor or intracranial neoplasm occurs when abnormal cells form within the brain.[1] There are two main types of tumors: malignant or cancerous tumors and benign tumors.[1] Cancerous tumors can be divided into primary tumors that started within the brain and those that spread from somewhere else known as brain metastasis tumors.[2] All types of brain tumors may produce symptoms that vary depending on the part of the brain involved.[1] These may include headaches, seizures, problem with vision, vomiting, and mental changes.[2] The headache is classically worst in the morning and goes away with vomiting.[1] More specific problems may include difficulty in walking, speaking and with sensation.[2][3] As the disease progresses unconsciousness may occur.[3]
