From: Analysis of primary risk factors for oral cancer from select US states with increasing rates
Analysis of state-specific oral cancer mortality data. Historical trends (1981-2005) of mortality from oral cancer were sorted by race and ethnicity using NCI SEER*Stat (National Cancer Institute Surveillance Epidemiology and End Results) and regression lines calculated using the Joinpoint Regression Program. A) Oral cancer deaths in Nevada were initially declining, but exhibited a distinct, sustained upward trend among white males beginning in 1995. B) US states previously identified with short-term increases in oral cancer rates were confirmed as NV, NC, IA, OH, ME, ID, ND and WY, while states sharing a contiguous border with Nevada generally experienced declining trends.
