Please forward this error difference between cancer and tumor pdf to 199. Brain metastasis in the right cerebral hemisphere from lung cancer shown on magnetic resonance imaging. A brain tumor occurs when abnormal cells form within the brain.

There are two main types of tumors: malignant or cancerous tumors and benign tumors. The cause of most brain tumors is unknown. Treatment may include some combination of surgery, radiation therapy, and chemotherapy. Anticonvulsant medication may be needed if seizures occur.

Secondary or metastatic brain tumors are more common than primary brain tumors, with about half of metastases coming from lung cancer. The main areas of the brain and limbic system. The signs and symptoms of brain tumors are broad. Primary and secondary brain tumors present with similar symptoms, depending on the location, size, and rate of growth of the tumor.

Headaches as a result of raised intracranial pressure can be an early symptom of brain cancer. However, isolated headache without other symptoms is rarer, and other symptoms often occur before headaches become common. This section needs additional citations for verification. The brain is divided into 4 lobes and each lobe or area has its own function. A tumor in any of these lobes may affect the area’s performance.

The location of the tumor is often linked to the symptoms experienced but each person may experience something different. Parietal lobe: Tumors here may result in poor interpretation of languages, decreased sense of touch and pain, and poor spatial and visual perception. Occipital lobe: Damage to this lobe may result in poor or loss of vision. Cerebellum: Tumors in this area may cause poor balance, muscle movement, and posture. Brain stem: Tumors on this can affect blood pressure, swallowing, and heartbeat. Despite the personality and behavior changes that occur in people with brain tumors, little research on such changes has been done.

A person’s personality may be altered due to the tumor damaging lobes of the brain. Personality changes can have damaging effects such as unemployment, unstable relationships, and a lack of control. Epidemiological studies are required to determine risk factors. Aside from exposure to vinyl chloride or ionizing radiation, there are no known environmental factors associated with brain tumors. Human brains are surrounded by a system of connective tissue membranes called meninges that separate the brain from the skull. The brains of humans and other vertebrates are composed of very soft tissue and have a gelatin-like texture.
