View in Spanish: Vigilancia activa

Active surveillance (AK-tiv ser-VAY-lents)
Closely watching a patient’s condition but not giving treatment unless there are changes in test results. Active surveillance avoids problems that may be caused by treatments such as radiation or surgery. It is used to find early signs that the condition is getting worse. During active surveillance, patients will be given certain exams and tests done on a regular schedule. It is sometimes used in prostate cancer. It is a type of expectant management.
