Screening Colonoscopy in Breast Cancer Patients
Screening Colonoscopy In Patients With Breast Cancer: Prevalence Of Colorectal Neoplasia In A Prospective Cohort
Source: ClinicalTrials.gov · Last updated 1 Jul 2026
Brief summary (registry, in English)
Breast cancer survivors may be at increased risk for developing colorectal polyps and colorectal cancer because of shared genetic, hormonal, and lifestyle-related risk factors. However, the prevalence of colorectal neoplasia in women with breast cancer has not been clearly established. This prospective screening study aims to evaluate the prevalence of colorectal polyps, adenomas, and colorectal cancer detected by screening colonoscopy in women who have completed treatment for breast cancer. The study also investigates whether clinical, pathological, and genetic characteristics of breast cancer are associated with the risk of colorectal neoplasia. All eligible participants undergo screening colonoscopy after completion of breast cancer treatment. The findings of this study may help identify breast cancer survivors who could benefit from individualized colorectal cancer screening strategies and contribute to improving long-term cancer survivorship care.
