What is the nervous system cancer?
In the human body, the nervous system is divided into two cuts: central nervous system (CNS) and peripheral nervous system (PNS). CNS consists of brain and spinal cord. PNS represents all other nerves associated with spinal cord to the body, as well as nerve cells and connective tissue. The nervous system cancer includes tumors that are formed in one or more parts of the nervous system. Tumors can affect the body in many ways because the nervous system allows the body to process sensory information through chemical signaling, procedural thinking and thinking, moving electrical signaling, providing speech and performing many other body functions.
The nervous system cancer is the second main type of cancer after leukemia. Gliomas that are cancer that affect the brain stem are the most common types of cancer, which account for 45 percent of all brain cancer. Ependymomas are tumors that are formed in brains that produce and deposit cerebrospinal fluid; Thyo tumors are usually formed on the upper or rear of the head. Oncologists distinguish different types of brain tumors based on the location of the tumor in the brain. For example, tumors that develop in the pineal part of the brain are called pineoblastomas.
The nervous system cancer can affect the eye. Cancer that affects the retina is called retinoblastoma and cancer that affects the optical nerve, is called gliom of optical nerve. Neuroblastomes are cancer cells placed in the adrenal cells in the body or other tissues of the nervous system, such as the adrenal glands, around the spinal cord or in the abdomen. Other types of cancer are, among other things, craniopharyngeom, intracranial tumor and astrocytoma of intracranial germ cells.
The diagnosis of the nervous system cancer may initially be difficult because the symptoms of cancer mimic Commone aills: headache, vomiting, nausea or drowsiness. The more apparent symptoms of the CancerNY nervous system includes dual vision, loss of memory or speech, localized weakness, severe headaches and seizures. Early diagnosis and treatment are essential for successful recovery.
The treatment of the nervous system cancer usually involves surgery in tumor removal. Brain cancer are much more common than spinal cord cancer and rarely spread to other parts of the body. Radiation therapy and chemotherapy treat and control metastatic tumors from other areas of the body, such as lungs or breasts to prevent cancer cells in brain involvement.
