Cancer Screening Considerations
➤ Obesity elevates the risk for several malignancies, including
breast, colorectal, endometrial, kidney, liver, ovarian, pancreatic,
and prostate cancers, underscoring the importance of diligent,
guideline-based cancer screening, such as mammography,
colonoscopy, and cervical cytology, with adjustments as
needed for age, sex, and risk profile. The Cancer Screening
Recommendations table lists screening recommendations for each
cancer type. In individuals with obesity, special considerations may
include technical challenges with imaging, the need for specialized
equipment, and tailored screening intervals, all of which require
close coordination among care teams to ensure thorough
evaluation and management of abnormal findings.
