   Melanoma of the skin: men 3.5% (1 in 29) risk of developing, 0.4% (1 in 269) risk of dying; women 2.5% (1 in 40) risk of developing, 0.2% (1 in 496) risk of dying — figures are for non-Hispanic White people

   ACS uses SEER mortality and incidence data (2020-2022) to compute direct lifetime probabilities from a life-table conditional on birth. The 3.5% male and 2.5% female figures are the gold standard for US non-Hispanic white lifetime melanoma diagnosis risk. Sex-averaged midpoint: (0.035 + 0.025) / 2 = 0.030; weighted slightly toward the male rate (higher incidence, larger share of melanoma burden) gives ~0.034 as the headline. Uncertainty band 0.025-0.045 spans the female-only to the upper bound for high-UV-exposure male subgroups.

   Independencia

   ACS lifetime probability tables are built directly on SEER 2020-2022 incidence/mortality data and life tables from the same NCHS pipeline referenced by the SEER Stat Facts source below. Treat ACS and SEER as one analytical pipeline on a shared upstream dataset; the AAD and Green (Nambour RCT) sources provide the genuine independent verification.

   Approximately 2.2% of men and women will be diagnosed with melanoma at some point during their lifetime; non-Hispanic white males 39.7 per 100,000/year, non-Hispanic white females 26.8 per 100,000/year; 5-year relative survival 94.7%

   SEER's 2.2% overall figure covers all races/ethnicities. Non-Hispanic white incidence rates (39.7 M, 26.8 F per 100,000/year) are roughly 30-40x the rates for Black Americans (1.0 M, 0.9 F), confirming the enormous racial disparity that justifies scoping this entry to fair-skinned adults. The 94.7% 5-year survival rate underscores that melanoma diagnosis risk far exceeds mortality risk.

   Independencia

   SEER is the upstream data source for the ACS lifetime probability calculations in source 1. Treat as the same pipeline for incidence/mortality figures; included here for the race-stratified incidence rates and overall population figure.

   Reduced melanoma after regular sunscreen use: randomized trial follow-up

   Estadística

   Daily sunscreen users had half the melanoma incidence of discretionary users (HR 0.50, 95% CI 0.24-1.02); invasive melanoma reduction was 73% (HR 0.27, 95% CI 0.08-0.97)

   Extracto

   “"11 new primary melanomas had been identified in the daily sunscreen group, and 22 had been identified in the discretionary group (hazard ratio [HR], 0.50; 95% CI, 0.24 to 1.02; P = .051). The reduction in invasive melanomas was substantial (n = 3 in active v 11 in control group; HR, 0.27; 95% CI, 0.08 to 0.97)." ”

   The Nambour RCT (Queensland, Australia; 1,621 participants; 1992-2006 follow-up) is the only large-scale randomized trial of sunscreen for melanoma prevention. The overall HR of 0.50 (borderline significance at p=.051) and the invasive-melanoma HR of 0.27 (significant) anchor the "~50% melanoma reduction with regular sunscreen" claim used in personal_factor_multipliers. The wide confidence intervals reflect the relatively small number of melanoma events (33 total) over the 10-year follow-up.

   1 in 28 men and 1 in 39 women lifetime melanoma risk; 5+ blistering sunburns age 15-20 increases melanoma risk by 80%; indoor tanning before 30 increases melanoma risk 6x for women

   “"It is estimated that melanoma will affect 1 in 28 men and 1 in 39 women in their lifetime. [...] Experiencing five or more blistering sunburns between ages 15 and 20 increases one's melanoma risk by 80% and nonmelanoma skin cancer risk by 68%." ”

   AAD figures (1 in 28 M, 1 in 39 F) are marginally different from ACS (1 in 29 M, 1 in 40 F) due to different data vintage and rounding; both are within expected variation. The 80% sunburn multiplier (5+ blistering sunburns age 15-20) and the indoor tanning risk figures are used in personal_factor_multipliers.

   Independencia

   AAD compiles statistics from multiple sources including SEER, ACS, and independent dermatology literature. The sunburn and tanning bed figures derive from separate epidemiological studies (Lew et al., Lazovich et al.) and are independently sourced from the SEER lifetime probability.

   The 234,680 figure originates from the American Cancer Society's "Cancer Facts & Figures 2026" annual report (122,680 in situ + 112,000 invasive = 234,680 total new US melanoma cases estimated for 2026); AIM at Melanoma Foundation's statistics sheet reproduces the ACS estimate. Used here to source the body text's "234,680 new cases projected for 2026" figure, which supports the entry's fifth-most-common-cancer underrated framing.

   Distinct from the ACS lifetime-probability tables (source 1) and SEER Stat Facts (source 2) used elsewhere in this entry — this source is used solely for the annual new-case count estimate, not the lifetime probability figures.
