Researchers detail in "Sun exposure and prostate cancer risk: evidence for a protective effect of early-life exposure," new data in prostate cancer. "Mounting experimental and epidemiologic evidence supports the hypothesis that vitamin D reduces the risk of prostate cancer. Some evidence suggests that prostate cancer risk may be influenced by sun exposure early in life," scientists in the United States report. "We analyzed data from the National Health and Nutrition Examination Survey I Epidemiologic Follow-up Study to examine associations of prostate cancer risk with early-life and adult residential sun exposure and adult sun exposures that were assessed through self-report, physician report, and dermatologic examination. We used solar...

Research findings, "Overdiagnosis and overtreatment of early detected prostate cancer," are discussed in a new report. "Early detection of prostate cancer is associated with the diagnosis of a considerable proportion of cancers that are indolent, and that will hardly ever become symptomatic during lifetime. Such overdiagnosis should be avoided in all forms of screening because of potential adverse psychological and somatic side effects," scientists writing in the World Journal of Urology report. "The main threat of overdiagnosis is overtreatment of indolent disease. Men with prostate cancer that is likely to be indolent may be offered active surveillance," wrote C.H. Bangma and colleagues, Erasmus University, Department of Urology. Th...

When a prostate shifts during radiation treatment for prostate cancer, technicians run the risk of missing the tumor and radiating healthy tissue. Now, experts say new technology is making it easier to track the position and motion of a patient's prostate with GPS-like precision during treatment.

When prostate cancer spreads, the prognosis can be grim. However, a Bay Area hospital is hoping a new medication can change that.
