What does a PSA test screen for?

• A. Breast cancer
• B. Skin cancer
• C. Prostate cancer
• D. Lung cancer

Answer: (C)

The PSA test, or Prostate-Specific Antigen test, is specifically designed to screen for prostate cancer. It measures the level of PSA in the blood, which can be elevated in men who have prostate cancer. While elevated PSA levels can also occur due to other prostate conditions, such as benign prostatic hyperplasia or prostatitis, the primary use of the test is to help in the early detection of prostate cancer. Understanding the other options clarifies why they do not fit with what the PSA test screens for. For instance, breast cancer is typically screened for using mammograms and breast exams, skin cancer is commonly screened through skin checks and biopsies, and lung cancer screening usually involves imaging tests like chest x-rays or CT scans. Each type of cancer has its own specific screening methods tailored to the particular characteristics and risk factors associated with that cancer.
