Exposure to Toxin in Certain Foods Could Cause Testicular Cancer
A Wake Forest University cancer researcher has proposed that a compound found in certain foods
may be a cause of testicular cancer in young men. Writing in the February issue of Cancer Causes and Control, Gary G.
Schwartz, Ph.D., M.P.H., Ph.D., proposes that exposure to a common carcinogen called ochratoxin A during childhood or
even before birth may set up the testes so that testicular growth during puberty triggers the launch of testicular cancer. more

Researchers Challenge Value Of Widely Used Prostate Cancer Diagnostic Methods
"Serendipity" rather than science plays a prominent role in the current diagnosis of prostate cancer,
according to Stanford University Medical Center researchers. A new study finds that prostate specific antigen (PSA), a marker
traditionally used by doctors as an indicator of prostate cancer risk, is clinically unreliable. more

Information For Patients: Prostate Cancer Screening
Screening for cancer is examination (or testing) of people for early stages in the development of cancer
even though they have no symptoms. Scientists have studied patterns of cancer in the population to learn which people are more
likely to get certain types of cancer. They have also studied what things around us and what things we do in our lives may cause
cancer. This information sometimes helps doctors recommend who should be screened for certain types of cancer, what types
of screening tests people should have, and how often these tests should be done. Not all screening tests are helpful, and most
have risks such as bleeding or infection due to a biopsy of the prostate for an abnormal PSA blood test. For this reason,
scientists at the National Cancer Institute are studying many screening tests to find out how useful they are and to determine the
relative benefits and harms. more

Stanford Researchers Home In On Huntington's Disease Treatment
Stanford University Medical Center researchers have discovered a potential treatment for Huntington's
disease. By enhancing the brain's natural protective response to the disease, researchers were able to alleviate the uncontrollable
tremors and prolong the lives of mice with a neurological disorder that mimics Huntington's. Their finding suggests that a similar
treatment strategy may be effective in humans. more

US National Cancer Institute (NCI) Statement on Mammography
A recent report in the scientific literature has reawakened debate about the value of screening
mammograms. The analysis, which appeared in The Lancet on 20 October 2001, reviewed the large, long-term mammography
trials upon which the National Cancer Institute (NCI) and other groups have based their recommendations and guidelines
concerning mammography screening. This review cited a number of possible flaws in the conduct of the trials and the methods
used to analyze the data. more
