Study into second cancer risk for testicular cancer survivors

Diagnostic radiation and second cancer risk in testicular cancer survivors  ” ecancer medical science 30/08/2011 ,by ecancer reporter Clare Sansom The link between radiation exposure and cancer first became evident in studies of survivors of the atomic bombings of Hiroshima and Nagasaki in 1945.

Later studies established a link between therapeutic radiotherapy for cancer and increased risk of a second subsequent malignancy. There have, however, been few large, comprehensive studies to date of the association between the lower radiation levels associated with diagnostic testing and subsequent cancer risk.

Testicular cancer is one of the most treatable solid tumours, but survivors of this disease need regular monitoring for recurrence, generally through repeated X-ray computer tomography (CT) scans……..

As cancers are known to take a minimum of five years to develop following radiation exposure, all patients who received a second cancer diagnosis or died within five years of developing their testicular cancer were also excluded from the study…………. The resulting study population included 2,569 men with a mean age at diagnosis of 34.7 years, and who were observed for a median time of 11.2 years….

Van Walraven and his co-workers concluded from this study that the risk of developing a second abdominal-pelvic cancer following recovery from testicular cancer and its associated diagnostic radiation is very low.. http://www.ecancermedicalscience.com/news-insider-news.asp?itemId=1968
