To determine prostate cancer, it is necessary to combine the indicators of anal diagnosis, laboratory tests, imaging tests, puncture biopsy and other tests to make a comprehensive judgment.
1. Anal diagnosis: Wearing gloves, touch the surface of prostate from anus to determine whether there are nodules or hard lumps. If nodules or hard lumps are felt and the prostate is hard, it suggests that there may be prostate cancer.
2 Laboratory examination: the earliest indicator used is prostate-specific antigen, the normal level is 0-4ng/ml, if more than 4ng/ml, there may be prostate cancer tendency. Others include the ratio of fPSA to tPSA, PSAV, PSAD and so on.
3. Imaging examination: such as transrectal ultrasound of the prostate, nuclear magnetic resonance of the prostate, whole-body nuclide bone imaging, positron emission computed tomography, etc.. It can find out whether there is occupation of prostate tissue, whether there is a mass and so on.
4. Puncture biopsy: If the above tests indicate abnormality, then prostate puncture biopsy is needed, which is the most reliable way to check prostate cancer.
If you have prostate problems, please consult a regular hospital in time, complete the relevant examinations and take active treatment.
