Debate about the use of prostate-specific antigen (PSA) tests to screen prostate cancer in men is ongoing. Prostate cancer is the most common cancer after skin cancer in men and the second most deadly after lung cancer. An elevated PSA level can lead to this cancer's diagnosis and treatment even before the onset of symptoms. However, other causes also can create a high PSA level, which may lead to men being unnecessarily treated for prostate cancer. This article will shed some light on the issue and discuss prostate cancer screening.

To compare the diagnostic accuracy of five internationally used indolent prostate cancer screen protocols in Chinese prostate cancer patients.
To evaluate changes in the serum levels of prostate specific antigen (PSA), %free PSA and -2proPSA biomarkers, and prostate health index (PHI) in the diagnostic algorithm of early prostate cancer.
To reduce the number of unnecessary biopsies in patients with benign prostatic disease, however, without missing significant PCa the present study re-evaluates the age-dependent PSA cut-offs in the Ty...
In 1899, Freud introduced the concept of screen memories. His insights were revolutionary: screen memories do not emerge into consciousness at the time of recall, he argued; they are formed at that ti...
In addition to TNM stage, there are adverse tumour and host factors, such as venous invasion and the presence of an elevated systemic inflammatory response (SIR) that influence the outcome in colorect...
The study measures the impact of "screen–and-treat" on the prevalence of high-grade cervical intraepithelial neoplasia and cancer (CIN 2+). It is a three-arm, randomized clinical trial c...
The purpose of this study is to determine whether or not participation in an experimental program called the "P4 program" is useful to men who are faced with choices about treatment for th...
Early detection of prostrate cancer and development of metastases. The research will attempt to match the SCM test (structuredness of the cytoplasmic matrix) in lymphocytes as an early can...
Prostate specific antigen (PSA) and digital rectal exam (DRE) are used to screen for prostate cancer. Patients with abnormal DRE or elevated PSA undergo transrectal ultrasound guided biops...
The primary purpose of this study is to determine the effectiveness of a multi-media presentation and survey to increase screening for colorectal cancer. Content of this presentation is b...
Screens which absorb the energy in the x-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less x-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen.
Methods to identify and characterize cancer in the early stages of disease and predict tumor behavior.
A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.

A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Production of an image when x-rays strike a fluorescent screen.
Prostate cancer (cancer de prostata) Prostate cancer (cancer de prostata) is a form of cancer that develops in the prostate, a gland in the male reproductive system. Most prostate cancers are slow growing; however, there are cases of aggressive prostat...
