Welcome  to  Public  health  moment from  the  University  of  Minnesota. More  than  200,000  men  will be  diagnosed  with  prostate  cancer  this  year, and  27,000  will  die. Yet  there  is  no  clear  evidence  that  being screened  for  prostate  cancer  is  beneficial. That's  according  to  Tim  Church, a  University  of  Minnesota  expert  on  cancer  screenings. Screening  for  prostate  cancer  has  been a  hot  topic  ever  since  the  PSA, the  prostate  specific  antigen  test  was  invented. To  date,  no  well  designed  clinical  studies have  demonstrated  that  there's a  clear  consistent  benefit  of screening  using  PSA  to reduce  either  the  deaths  from prostate  cancer  or  to  reduce  the  amount  of  illness. Church  says  that  the  decision  to be  screened  for  prostate  cancer is  a  personal  one  that  a  man should  make  after  consulting  his  Dr. Most  prostate  cancer  is  not an  aggressive  cancer  and probably  won't  kill  the  man  who  has  it. Unfortunately,  there  is  a  non  trivial  proportion  of prostate  cancer  that  is  aggressive  and  does  need  to  be treated  if  we're  to  prevent  illness  and  death. Church  is  currently  conducting a  research  trial  involving  75,000  men. He  expects  it  will  provide an  answer  to  whether  screening  for prostate  cancer  actually  does save  lives  with  another  public  health  moment. I'm  John  Finnegan.
