    CT scans can reduce risk of lung cancer death
    (2010-11-16) Engebretson, Mark; Tim Church
    Welcome to Public Health Moment from the University of Minnesota. Heavy smokers who receive annual CT scans, instead of standard X-rays, reduce their risk of dying from lung cancer by 20 percent. That’s according to a study of 53,000 smokers. Tim Church, a University of Minnesota expert on cancer screenings, led the study in Minnesota. Despite the good news, Church says additional research needs to be done before CT scans can be recommended as a standard. That’s because a positive screening now requires additional testing to ensure that the positive finding is indeed cancer. This could range from additional radiological testing to surgery to remove parts of a lung. For Public Health Moment, I’m Mark Engebretson.

    Prostate cancer screening effectiveness
    (2009-03-19) Engebretson, Mark; Tim Church
    Welcome to Public Health Moment from the University of Minnesota. Being screened for prostate cancer does not appear to reduce your chance of dying from the disease. That’s according to a new report from the from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial than 76,000 men. Tim Church, a University of Minnesota expert on cancer screenings, was the study’s lead researcher. The finding is important because there are negative consequences to screening, Church says. For John Finnegan and Public Health Moment, I’m Mark Engebretson.

    PSA screening has resulted in more harm than good.
    (2011-12-08) Engebretson, Mark; Tim Church
    Should any man of any age -- absent symptoms -- ever be screened for prostate cancer using the Prostate-Specific Antigen (Or PSA) test? No, according to draft guidelines recommended by the U.S. Preventive Services Task Force. Public comment on the draft guidelines is open until Dec. 13. University of Minnesota professor Tim Church, who has conducted clinical trials to measure the success of PSA screenings, said that research has shown that these tests have resulted in more harm than good. The draft recommendations do not specify whether men of higher risk should be screened. But Church says that men concerned about prostate cancer should consult with their doctor.

    PSA screening not clearly beneficial
    (2007-06-08) Finnegan, John; Tim Church
    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, says Tim Church, a University of Minnesota expert on cancer screenings. Church says that the decision to be screened for prostate cancer is a personal one that a man should make after consulting his doctor. 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.

    Sigmoidoscopy screening reduces risk of colorectal cancer death.
    (2012-06-08) Engebretson, Mark; Tim Church
    Welcome to Public Health Moment from the University of Minnesota. The use of flexible sigmoidoscopy screening reduces deaths from colorectal cancer cases by more than 25 percent. That’s according to results from the first randomized clinical trial in the United States that looked at the effectiveness of sigmoidoscopy. Tim Church a University of Minnesota cancer prevention expert, said 155,000 people involved were in the study, including more than 29,000 people in Minnesota. Church says the results provide patients with freedom of choice when it comes to screening options for colorectal cancer and should result in more people being screened.
