Context: Treatment Option Overview / The following types of treatment are used:

Active surveillance is closely watching a patient’s condition but not giving any treatment unless there are changes in test results that show the condition is getting worse. Active surveillance may be used to avoid or delay the need for treatments such as radiation therapy or surgery, which can cause side effects or other problems. During active surveillance, certain exams and tests are done on a regular schedule. Active surveillance may be used for very slow-growing tumors that do not cause symptoms.
