Weighty issue with prostate cancer

Recent research has linked obesity with an increase in lifetime risk of prostate cancer. Most of the study subjects were identified by increased blood levels of the prostate specific antigen (PSA), which is used as an indicator of prostate cancer. Increased risk was due to reduced ability of doctors to effectively perform a digital rectal examination, which is a main diagnostic test. Fat cells also produce more estrogen-like hormones that artificially lower the level of PSA. These findings conflict with other data that highlights the lower level of testosterone in obese men, reducing their prostate cancer risk.
