The brain is the organ in a person's skull that controls the functions of all of the other organs. Together, the brain and spine make up the central nervous system. The brain is responsible for the experience of the five senses (taste, touch, sight, hearing and smell). The brain is also the seat of thought, language, personality, creativity and memory. The brain controls movement, sensation, balance, and coordination. In order to do its job, the brain requires an enormous amount of the oxygen and nutrient energy that a person takes in regularly.

Types of Brain Tumors

There are many different types of brain tumors, based on what cells are affected and how they appear under a microscope. Tumors can be classified into four general categories:

1)Gliomas

2)Astrocytoma

3)Grade I (pilocytic astrocytoma): slow growing, with little tendency to infiltrate surrounding brain tissue. Most common in children and adolescents.

4)Grade II (diffuse astrocytoma): fairly slow-growing, with some tendency to infiltrate surrounding brain tissue.

Causes of a brain tumor

Exact and definite causes of brain tumors are still not known and their reasons remain ambiguous. It is quite clear though that it is never contagious and a person cannot "catch it" from some one having a tumor.

Though the exact cause still eludes us, there are certain risk factors that increase the chances of one developing the tumor. Gender is a dominant risk factor. They are predominantly detected in males. Age too is a risk factor. Majority of the cases show tumor developing in people at the age of 60 and above. Also, children below the age of 8 years are more prone to develop it. Other risk factors include family history and exposure to radiations.

Symptoms:

With a brain tumor, neck pain can occur at times, but recurring headaches are the most frequent sign of a brain tumor. But diagnosis can be difficult. Most people have headaches, and many have recurring headaches or migraines - but not a brain tumor. Headaches that are caused by brain tumors usually have other symptoms that occur simultaneously.

Double vision, vomiting, or confusion are commonly seen with headaches associated with brain tumors, but again, severe migraine sufferers can have these symptoms as well. Sometimes the headaches come while asleep, and are noticed strongly immediately upon awakening, but subside after a few hours. Brain tumors can also cause headaches that get worse with exercise or coughing.

If a brain tumor is still small and fairly young, it can often be treated. However, most symptoms depend on the size of the tumor and where it's found in the brain. For example, a benign tumor may take years to grow and even longer to cause an identifiable sign.

Among the basic harbingers are relentless or continual headaches, especially those that occur at night or are there immediately when an individual wakes up. Typically in young children, headaches happen simultaneously with vomiting or nausea.

As you can see the different tumors exhibit different symptoms.

You need to look out for any brain tumor symptoms and if there appears to be a problem get it check by a qualified medical person immediately.
