What laboratory marker might be elevated in cases of Prostate Cancer?

The elevated laboratory marker commonly associated with prostate cancer is Prostate-Specific Antigen (PSA). PSA is a protein produced by both normal and malignant cells of the prostate gland, and its levels can be elevated due to prostate cancer, benign prostatic hyperplasia (BPH), or prostatitis. In clinical practice, PSA is often used as a screening tool to detect prostate cancer in men, as higher levels can suggest the presence of cancer, although it is not exclusively indicative of malignancy.

Monitoring PSA levels can also be helpful in assessing treatment responses and disease progression in patients already diagnosed with prostate cancer. The specificity of PSA for prostate conditions makes it a critical marker in the evaluation and management of prostate health.

The other markers listed are used for different types of cancers or conditions and do not hold significance in the context of prostate cancer; hence they are not relevant for this specific question regarding elevated markers in prostate cancer.
