Brain Cancer

Brain Cancer:

Brain cancer is a disease in which cancer cells are found in the brain. Brain cancer is known as brain tumor. There are two types of brain tumors: primary brain tumors and metastatic (secondary) brain tumors. Primary brain tumors originate in the brain. Primary brain tumors can be cancerous or noncancerous. Both types take up space in the brain and may cause serious symptoms. The most common symptoms and complications are vision loss, hearing loss and stroke. A noncancerous primary brain tumor is life threatening when it compromises vital structures. Metastatic (secondary) brain tumors are brain tumors that that originate from cancer cells that have spread from other parts of the body.

Symptoms of Brain Tumors:

There are many symptoms of brain tumors. The symptoms will depend on the part of the brain the tumor is located. The most common symptoms of brain tumors are: 1.Nausea 2.Vomiting 3.Headaches 4.Behavioral and emotional changes 5.Impaired judgment 6.Loss of hearing 7.Impaired sense of smell 8.Memory loss 9.Muscle weakness 10.Paralysis on one side of the body

Causes of Brain Tumors:

Cancer can occur in any part of the Brain or Spinal Cord. Cancer cells are abnormal cells that divide too frequently and without any order. The causes of central nervous system tumors are not known. In addition, scientists cannot explain why Brain Tumors develop in healthy adults. Certain factors have been identified that may increase someone's chance of developing a Brain Tumor. Consider the following information; workers in certain industries such as oil refining, rubber manufacturing, and drug manufacturing industries have higher rates of select types of Brain Tumors. Researchers are also studying families in which multiple members have developed the same type of Brain Tumor to see whether heredity plays a role. Researchers are also looking at the connection between viral infections and exposure to radiation as a cause of Brain Tumors. There is no research to suggest that injuries to the head cause or increase anyone's risk for developing a Brain Tumor. Because most patients diagnosed with a Brain Tumor have no identifiable risk factors, it is believed that Brain Tumors are the result of many factors working together.
