Radiation Increase Brain Cancer Risk In Children

Children who are affected by exposure to radiation therapy before the age of five are known to have risk for tumors in the brain or central nervous system a few years later. Data were obtained from studies of children who survive childhood cancer. Types of nerve tumors are often found in children are gliomas and meningiomas, which are generally found in the brain and other parts.

Approximately 1% of the total cancer patients aged children are able to survive in an interval of many years known to be affected by a tumor on her nervous system if they are exposed to radiation. The highest risk for second cancer (cancer of the nervous system) for children who undergo radiation therapy at very young ages have a chance to develop into brain cancer later in life.

A study involving 14 361 patients with cancer at the age of children who survive five years after liberated from cancer, including 116 children suffering from cancer a few years later the nerve. A total of 40 people whom suffer from intermittent gliomas nine years after the first cancer free at the age of the children and 66 of them suffering from cancer meningiomas lapse 17 years after first declared cured of cancer at the age of the children.

Healing by means of radiation is known to have a risk up to six times more likely to cause the occurrence of gliomas and ten-fold to hit meningioma. The risk of developing cancer of the nerves will increase along with increasing doses of radiation used for treatment of first cancer treatment he suffered.

However, the researchers concluded that there is need for further observations of the children are able to survive from cancer at a young age especially those undergoing radiation therapy for a clue or early detection of cancer types that will strike next.
