The nervous system is a very complex network of cells and nerves that carry messages to different parts of the body right from the brain and spinal cord. Together the nervous system allows our brain to control what is going on and helps different parts of our body to communicate.
There are two main sections of the Nervous system:
1. Central nervous system (CNS)
2. Peripheral nervous system (PNS)
The brain and the spinal cord make up the central nervous system (CNS). Network of nerves make up the peripheral nervous system (PNS). The nerve network connects the rest of the body to the Central nervous system (CNS). It comprises of nerve fibers that carry information between the CNS and other parts of the body.
The tumor forms in one or more parts of the nervous system resulting in Nervous system cancer. The body can be affected in numerous ways due to the tumor, because the nervous system allows the body to process sensory information through chemical signaling, process thought and reasoning, move muscles through electrical signaling provide speech and perform many other bodily functions. After leukemia, cancer of Nervous system is the 2nd leading type of cancer in children.
Types of Brain Cancers:
A mass of cells in your brain is known as brain tumor and that isn’t considered normal. Brain tumors are bifurcated into two general groups:
Primary Brain Tumors
Primary brain tumors develop in the brain and inclined to stay there.
Below are some of the Primary brain tumors:
Secondary Brain Tumors
Compared to primary tumors, the secondary brain tumors are more common. These cancers develop in some other organs of the body and then travel to the brain. Some of the most common cancers that spread to the brain include

The role of the nervous system is to receive information and allow the body to respond quickly to various stimuli. The four important functions of the Nervous System are the sensory, integrative, communicative and motor functions.
The tumors that affect the Nervous System are Astrocytomas, Glioblastomas, Oligodendroglial tumors, Ependymal, Medulloblastomas, Pineal, Meningeal and Germ Cell tumors.
Parkinson's disease, Multiple sclerosis (MS), Amyotrophic lateral sclerosis (ALS), Alzheimer's disease, Huntington's disease, Peripheral neuropathies are some of the common disorders of the nervous system.
The signs of a brain tumor depend on the brain tumor's size, location and rate of growth. Common signs and symptoms may include: change in pattern of headaches. Headaches that gradually becomes more frequent and more severe nausea or vomiting.
Some types of cancers that affect the nervous system can cause neuropathy. Tumors that grow in or near the brain or spine, especially, can lead to nerve damage. However, any cancer that causes the growth of tumors can lead to neuropathy.
Symptoms:Primary brain cancers have below symptoms
Below are some less specific symptoms:
Risks Factors for Brain Cancer:
Family history: Those are at risks who have a family history of brain tumors
Age: Brain tumors risks increases with age.
Chemical exposure: Being constantly exposed to certain chemicals can increase risk for brain cancer.
Exposure to radiation: Those who have been exposed to ionizing radiation are also at risk.
