Red Flag Origin

DefinitionChronic high cumulative occupational outdoor UV exposure (≥10 years outdoor work in high-UV-index latitudes — agricultural workers, fishermen, sailors, construction trades, road workers, lifeguards, landscapers, equatorial / sub-tropical residence with daily outdoor exposure). Solar UV radiation is an IARC Group 1 carcinogen (Monograph 100D, 2012) — established etiologic driver of cutaneous squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and melanoma. Occupational outdoor work raises non-melanoma skin cancer (NMSC) risk ~1.5-2x baseline (meta-analyses of outdoor vs indoor worker cohorts); melanoma signal is weaker for chronic occupational UV but strong for intermittent / sunburn-pattern exposure. Risk compounds with Fitzpatrick skin type I-III, age >50, history of ≥5 sunburns, immunosuppression (transplant, autoimmune disease on therapy). Mechanisms: UVB (290-320 nm) directly...

Notes

Prevention-persona RedFlag for chronic occupational outdoor UV exposure ≥10y in high-UV-index latitudes. IARC Group 1 solar UV. Distinct from broader RF-LIFESTYLE-UV-EXPOSURE-PREVENTION (which covers tanning beds + sunburn history + recreational UV). Anchored to DIS-BCC per task brief (closest skin DIS to UV-NMSC). Engine routes to PreventionPlan recommending photoprotection counseling + clinical skin exam cadence + patient skin self-exam education + Vitamin D balance. STUB pending two-Clinical-Co-Lead signoff per CHARTER §6.1 dev-mode.
