The article focuses on the risk of prostate-specific antigen (PSA) testing. Peter Scardino, Managing Director of Memorial Sloan Kettering Cancer Center in New York, observes that to reduce the potential harm of
The US Preventive Services Task Force (USPTF) recommends that middle-aged men not receive the prostate-specific antigen test (PSA) because research has shown that the benefits of testing do not outweigh the risks, which include false positive results. More than three-quarters of the men who pa...
There are only a few estimates of absolute risks of PCa for BRCA1/2 mutation carriers and those are based on retrospective studies [4], [6], [7], [13], [15], [17], [21], [22]. Given the rapidly rising incidence of PCa in the prostate-specific antigen (PSA) testing era, retro...
PSA is a protein made by cells in the prostate gland. Only small amounts of this protein are found in the blood. The PSA blood test measures PSA in units called nanograms per milliliter (ng/mL). As PSA measures rise, so do the risks of prostate cancer. There is no exact PSA number...

Nanotechnology holds immense promise in revolutionising healthcare, offering unprecedented opportunities in diagnostics, drug delivery, cancer therapy, and combating infectious diseases. This review explores the multifaceted landscape of nanotechnology i
Frequent monitoring of CABG patients with physiologic testing can identify early problems in grafts. PTCA (angioplasty) with stenting, in addition to aggressive risk factor modification, may significantly limit the need for repeat CABG years later. Repeat CABG surgery is occasionally necessary, but may...
A large, retrospective study has found that high-risk prostate cancer that can only be detected through PSA testing is more likely to occur among men over the age of 75 and in African Americans. Hong Zhang, MD, PhD A large, retrospective study has found that high-risk prostate cancer that...
(55–69 years) for which the U.S. Preventive Services Task Force recommends discussing PSA testing with their doctor. Making aninformed decisionrequires that they have a clear understanding of the magnitude of the potential risks and benefits of screening, and of each step that might follow it...
and 1.5 mL of the upper supernatant of each sample was transferred to a 2-mL cleanup tube containing different sorbents: for the vegetable, fruit, and cereal samples, 50 mg PSA + 10 mg GCB + 150 mg MgSO4; for the pork, chicken egg, and cow milk samples, 50 mg PSA + 50 mg C18 ...
