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.

The purpose of this article is to review blood and urine tests that are currently available and under investigation for a role in prostate cancer screening and detection.
The diagnosis of prostate cancer (PCa) is currently based on serum PSA testing and/or abnormal digital rectal examination and histopathologic evaluation of prostate biopsies. The main drawback of PSA ...
Impact electrochemistry provides a useful alternative technique for the detection of silver nanoparticles in solutions. The combined use of impact electrochemistry on screen-printed electrodes (SPEs) ...
Full-field digital mammography (FFDM) has replaced screen-film mammography (SFM) in most breast cancer screening programs due to technological advantages such as possibilities to adjust contrast, bett...
To determine the amount of daily screen time in children 18 months of age and ascertain correlations that may be contributing to excessive screen use.
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...
The investigators intend to screen children who are suspected of having GAS tonsillitis. From each child we will take a throat culture and saliva sample to screen for molecular evidence of...
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...
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...
