Obesity ''may distort cancer test''
Doctors must take body weight into account when reading test results for prostate cancer, a US study argues.
London''s Cancer Hot Spots
A new study has found that Kingston is London''s hot spot for skin, breast and prostate cancer. It is one of the boroughs in the capital with the highest rates of all three types of cancer. The Cancer Inequalities in London report by the Thames Cancer Registry reveals stark differences in cancer levels in different areas. It shows the highest rates for skin cancer are in Kingston, Richmond & Twickenham, Sutton & Merton, Croydon and Havering. [click link for full article]
UC Davis Researchers Identify A Cellular Pathway That Makes Prostate Cancer Fatal
Expanding evidence that tiny strands of RNA - called microRNAs - play big roles in the progress of some cancers, UC Davis researchers have identified one that helps jump start prostate cancer cell growth midway through the disease process, eventually causing it to become fatal. The discovery is an important link to finding new treatments targeting this cellular function and reducing cancer deaths among American men. [click link for full article]
PSA test in obese men can produce false results
Scientists in the United States suggest a blood test widely used to screen for prostate cancer can be misleading in the case of men who are obese.
Why Obese Men Post Lower PSA Levels (HealthDay)
HealthDay - TUESDAY, Nov. 20 (HealthDay News) -- In recent years, doctors
have learned that they need to adjust the results of blood tests to
properly diagnose prostate cancer in obese men, but now researchers think
they know why.
Obesity can skew key prostate cancer test results (Reuters)
Reuters - Doctors reading the results of a
blood test widely used to screen for prostate cancer can be
fooled into thinking obese men are disease-free, researchers
said on Tuesday.
Obesity-linked high blood volumes render PSA prostate cancer test less effective, study suggests
The extra blood volume produced in the obese may so dilute levels of a telltale protein produced by prostates that the popular PSA test may be essentially useless for diagnosing prostate cancer in men carrying extra pounds, a new study in the Journal of the American Medical Association suggests.
Obesity associated with lower PSA levels in men with prostate cancer
Higher body mass index is associated with higher plasma volume, which may be related to lower prostate-specific antigen levels among obese men, according to a study in the Nov. 21 issue of JAMA.
