What does PSA stand for in the context of prostate cancer screening?

Prostate Specific Antigen
Prostate Sensitivity Assessment
Prostate Size Analysis
Prostatic Surface Area

The correct answer is: Prostate Specific Antigen

In the context of prostate cancer screening, PSA stands for Prostate Specific Antigen. This is a protein produced by both normal and malignant cells of the prostate gland. The measurement of PSA levels in the blood is a widely used method for screening and monitoring prostate cancer. Elevated levels of PSA can indicate the presence of prostate cancer or other prostate-related conditions, which is why it plays a crucial role in the early detection and management of the disease. Monitoring PSA levels can also help assess the effectiveness of treatments and detect possible recurrence of cancer. Understanding the significance of PSA is essential for oncology nurses in their practice related to prostate cancer care and patient education.
