Effective Cancer Screening Methods Essay -- Health, Screening, Early

Effective crab louse wake methods atomic number 18 used to detect or identify the presence of a unique(predicate) malignant neoplastic disease before the individual displays whatever symptoms of cancer. Early signal detection of a cancer through projection binding can save the life of a person who may have died without screening detection. Early detection of cancer can also provide a less costly and more effective treat handst than if the cancer progresses requiring more advanced or drastic treatment. Screenings runines for the more car park cancers such as breast, colon, prostate or cervical can be non-invasive or exactly slightly invasive. The majority of screening procedures are non-invasive which is more cost effective, patient convenient, and does not require any patient aftercare. Screening tests usually have a recommended age and frequency. As people age there is a higher risk of cancer and more screening is recommended. There are some considerations on whether to screen or not to screen such as is the cancer common or fatal, are there detectable symptoms, and how reliable are the test results (Bast, 2000). There are currently two slightly invasive screening tests used to detect prostate cancer. They are the digital rectal exam (DRE) and the prostate-specific antigen broth test (PSA). The DRE is a quick exam that can impede the prostates health. A doctor inserts a gloved and lubricated finger into the rectum to notion the back portion of the prostate for size, irregularity or abnormal areas. DRE is the only method in which a physician can physically see to it the prostate gland. If a doctor does find an irregularity the conclusion is not necessarily prostate cancer, but a reason to pursue diagnosis (Bast, 2000).Prostate-specific antigen (PSA) is a protein produced by cells of the prostate g... ...te posts coated with antibodies that bind to tumor cells. When blood passes across the chip, cancer cells stick and stains make them glow f or easy detection (Prostate.net, n.d.). This blood test could possibly eliminate tissue sampling and imaginativeness scans (Prostate.net, n.d.). EN2 is a new prostate cancer test measuring the EN2 protein in urine. The study found that interrogatory for the protein could accurately identify 66% of men with prostate cancer, and correctly rule out the disease in around 90% of men without the disease (National Health Service, 2011). The cases of prostate cancer were substantiate with a biopsy. The University of Surrey, UK studies confirmed that even if the EN2 test performs well in large scale testing, the test would not necessarily replace PSA testing (National Health Service, 2011) but could be used with PSA (National Health Service, 2011)
