Which statement about CA-125 testing is true?

Explanation:
CA-125 is a tumor marker that’s used mainly to follow how ovarian cancer responds to treatment and to watch for recurrence. By measuring its level over time, clinicians can see whether the disease is shrinking with therapy, staying stable, or progressing. It’s not a diagnostic test or a general screening tool, and many non-cancer conditions can raise CA-125, so it isn’t used to identify a Bartholin cyst, measure testosterone, or screen for prostate cancer (where PSA is typically used).
