Prostate cancer is the most common cancer in men and the second leading cause of cancer deaths. New advances in screening and imaging allow earlier diagnosis, and improved surgical techniques have reduced sexual dysfunction and incontinence that often resulted from radical prostatectomy. However, many questions remain. How can prostate cancer best be detected in an early curable form? What is the role of tumor markers? Who should be screened and how? What prognostic tools can help with decisions about appropriate therapy?
