Cancer prevention and risk-based screening

Established prevention measures remain the focus, including tobacco cessation, lower alcohol intake, HPV vaccination, healthy activity and weight, UV protection, and guideline-based screening. A Canadian screening guide offers useful plain-language discussion of false positives, HPV testing, mammography, colorectal screening, lung CT eligibility, and the absence of routine ovarian screening, but schedules require local and individual-risk context. Broad community reminders should not replace current USPSTF, ACS, ACOG, ACR, or applicable national guidance.
