Question

This gentleman had a radical prostatectomy by me 6 months ago.

His prostate-specific antigen is now 0.1 ng/ml (nanograms per
milliliter). He had a repeat prostate-specific antigen a few weeks
after th

Answer 1

Prostate-specific antigen (PSA) is a biomarker for detecting prostate cancer. A low PSA level (0.1 ng/ml) after a radical prostatectomy suggests successful treatment. Monitoring PSA levels is important for post-prostatectomy follow-up.

Step-by-step explanation:

Prostate-specific antigen (PSA) is a protein enzyme produced by the prostate gland. It is used as a biomarker to detect prostate cancer. Elevated levels of PSA can indicate the presence of prostate cancer, although other factors can also contribute to elevated PSA levels. A biopsy is necessary to confirm a diagnosis of prostate cancer.

In the case of the gentleman mentioned, his PSA level is currently 0.1 ng/ml, which is considered a low value. This suggests that the prostate cancer has been successfully treated through the radical prostatectomy. Monitoring the PSA level is an important aspect of post-prostatectomy follow-up to ensure that the cancer does not recur.
