The reason: The blood test that looks for elevated levels of the protein prostate-specific antigen ( PSA), indicating a heightened cancer risk, doesn't seem as reliable for obese men, Freedland said. Freedland说,常规的验血检测高水平的蛋白质前列腺特异性抗原(PSA)可表明癌症的风险加剧,但此检测对肥胖男性似乎并不可靠。
Asymptomatic men who have both a negative DRE and normal PSA blood test need only to continue an annual DRE and PSA check up. 对于无症状且指诊、前列腺特定抗原检查皆阴性者只要接受年度定期前列腺特定抗原检查和肛门指诊。
Everyone agrees that the proper evaluation of men with LUTS includes a PSA blood test and digital rectal examination as well as other studies. 大家都同意,在适当的评价男性下尿路症状包括变压吸附血液检查和直肠指诊以及其他研究。
Doctors typically conduct a biopsy when cancer is indicated by screening tests, such as a blood test for PSA, or by an irregular finding on a digital rectal exam. 当进行筛查如血液PSA检测或直肠指诊发现前列腺异常提示前列腺癌时,医生通常会进行活检。
A biopsy-surgery to remove and test small slices of the organ-typically follows the standard PSA blood test used to indicate the presence of disease. 通常为了指出这种疾病是否存在,我们要进行血PSA检测,然后才会进行活检即手术切除后观察器官的断层薄片。
