contralateral surveillance
Systematic monitoring of the opposite breast in patients with unilateral breast cancer to detect metachronous cancer development.
Full Definition
Contralateral surveillance involves the systematic imaging and clinical monitoring of the unaffected breast in patients diagnosed with unilateral breast cancer. This surveillance is crucial because breast cancer survivors have a 2-5 fold increased risk of developing cancer in the opposite breast compared to the general population. The surveillance protocol typically includes annual mammography of the contralateral breast, with consideration for supplemental MRI screening in high-risk patients such as BRCA mutation carriers or those with very dense breast tissue. Early detection of contralateral breast cancer significantly impacts treatment planning and overall survival outcomes.
Usage
Usage note: Distinguish from 'bilateral surveillance' which includes both breasts; this specifically refers to the unaffected breast.
