There is no known cause of brain cancer. Extensive research has been conducted to pinpoint a cause to help prevent the cancer from occurring. Although there has not been very much conclusive evidence leading to a cause of brain cancer, the one thing that doctors do know is that brain cancer is not contagious and it does not occur due to head injury. There are known instances where cancer has spread to the brain from other parts of the body.(Lung cancer,Breast cancer,Liver cancer and so on.)
Brain cancer can occur at any age. Studies have shown that two major age groups are affected. From ages 3 to 12 and 40 to 70 are the age groups when brain cancer is formed. Since researchers have been able to gather this data, it has led to the discovery of some risk factors. Workers in certain industries are at a higher risk for brain cancer than workers in other industries. These include, rubber manufacturing, drug manufacturing, and oil refining. Since brain cancer often occurs with members of the same family, heredity is believed to be another cause of brain cancer.
There are many different kinds of cells in the brain, each with a different function. Sometimes the cells inside the brain begin to grow uncontrollably leading to a tumor. A tumor in the brain may or may not be malignant.If benign a tumor stays where it starts, although it can grow very large and put pressure on crucial areas. In the case of a malignant brain tumor however this has the ability to spread and brain cancer occurs. Brain cancer is dangerous and life-threatening as the cancerous cells can interrupt vital brain functions. When brain cancer occurs, the cells continue to grow at a rapid pace. The cells and tissue around these cancerous cells become crowded out and invaded.
Symptoms of brain cancer include headaches that are worse in the morning, changes in personality, abnormal eye movements, and weakness in the arms and legs. Seizures, nausea, and drowsiness are other symptoms of brain cancer.
Surgery is the treatment of choice for primary brain tumors radiation therapy, and chemotherapy are the treatments that are used when cancer has spread to the brain. The doctor will use one or a combination of these treatments depending on the needs of the patient.
