The answer is B. Screening for cervical and colorectal cancer every six months for two years.
The guiding principle of surveillance is that it should consider a patient's risk of recurrence in the context of functional status and patient preferences.
American Cancer Society/American Society of Clinical Oncology (ASCO) Breast Cancer Survivorship Care Guidelines recommend age-appropriate screening for cervical and colorectal cancer as they would for patients in the general population. All other screening guidelines are part of the surveillance recommendations for breast cancer survivors based on the ACS/ASCO Guidelines.
