    Thus, any given patient could have a score of between two and ten——the higher the score, the more aggressive the cancer, and the lower the chance of survival. Gleason found the score directly related to survival rates in a study of 270 patients, which was the basis of his journal report.

    Of the many cancer-specific schemes, the Gleason system, [3] named after Donald Floyd Gleason, used to grade the adenocarcinoma cells in prostate cancer is the most famous.

    Prostate cancer screening is the screening process used to detect undiagnosed prostate cancer in men without signs or symptoms. [1] [2] When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates. [2] Screening precedes a diagnosis and subsequent treatment.
