Medical News Summary (summary of medical news story as reported by Forbes HealthDay): A study published in Cancer found that a relationship existed body mass index and prostate specific antigen level. High BMI was associated with a lower PSA level and thus obesity was related to lower PSA levels. It is believed that obesity reduces the level of testosterone which in turn reduces the level of PSA. High PSA levels are indicative of prostate cancer and thus obesity may mask the presence of the cancer through artificially low PSA. This supports findings in other studies that claim that overweight men had a higher risk of death from prostate cancer. Diagnosis of prostate cancer can be done through PSA tests or digital rectal exams. However, PSA tests have been under intense scrutiny recently over claims that it fails to diagnose many cancers. A researcher believes that prostate cancer screening should be undertaken by all at risk groups ie people who are older, black or have a family history of the disease
