Explaining Brain Cancer
Brain cancer or brain tumor (malignant) as simply put, is an abnormal growth of cells in the brain. To go ahead and further define it, it is any intra-cranial cancer instigated by uncontrolled and abnormal division of cells. It could be either in the brain, in the pineal nerves or in the cranial nerves. The interesting though shocking aspect is that those cells which form the components of the brain can lead to cancer. There is one thing which needs to be clarified. All the brain tumors are not malignant or cancerous. On the other hand, any type of cancer is tumor which is malignant. This abnormal growth is nothing but a mass of cells coming together.

Brain Cancer Causes and Symptoms
Before we go on to causes of brain cancer, lets see what are the symptoms first. The symptoms are:
???Headache
???Weakness
???Clumsiness
???Difficulty Walking
???Seizures
???Changes in concentration, memory, attention, or alertness
???Nausea, vomiting, especially early in the morning
???Vision Abnormalities
???Difficulty with speech
After the symptoms, lets take a look at the causes. Read more on

What Causes Brain Cancer
Radiation: Radiation is a major cause of brain cancer. Those who work in an industry where maximum work is related to nuclear energy, face the risk of getting brain cancer. The nuclear radiations are extremely harmful for the body.
Genetics and Heredity: If a person has history of brain cancer in their family, it can cause brain cancer. In other cases if there is a certain type of genetic mutation, where an individual could lack a particular type of tumor suppressing genes, it may lead to cancer.
Cancer in Other Parts of the body: This is one of the most common reason for brain cancer. These are called secondary brain tumors. These result from cancer initiated in some other part of the body and then spreads to the brain. These are more rampant than primary brain cancers. Most common amongst these are breast cancer, lung cancer, colon cancer, kidney cancer, melanoma (skin cancer), sarcoma and neuroblastoma.
Brain Tumor: As mentioned earlier, tumor may not necessarily be cancerous, but a cancer inevitably is a manifestation of malignant tumor cells. Thus, if there are tumor cells in the brain and they get malignant, it leads to brain cancer. Primary brain cancer is caused when the healthy and normal cells are mutated. Primary brain cancer cases are less in number than secondary though. Thus, tumor is one of the possible causes of brain cancer. Read more on stage 4 brain cancer.
Environmental Factors: Exposure to Vinyl Chloride is another factor causing brain cancer. Certain products made of plastic have this cancer causing agent. These could be plastic parts of a car, household items and types of wires.
Other Causes: Other brain cancer causes are smoking, HIV/Aids infection, work involving the chemicals formaldehyde and Acrylonitrile. There are other factors too, like age, race and sex. Men, apparently are more prone to cancer than women.
Although these are the most obvious and ?straight in the eye? reasons for what causes brain cancer, there is still a lot of research going on as to why and how exactly does this happen and why do these cells go in a tizzy and create problems for the body. Brain cancer causes are thus, ambiguous and the above causes are the most common on which a lot of studies have been done. This is where I sign off. Take Care!
