Purpose: There are complex and paradoxical patterns in lung cancer incidence by race/ethnicity and gender; compared to non-Hispanic White (NHW) males, non-Hispanic Black (NHB) males smoke fewer cigarettes per day and less frequently but have higher lung cancer rates. Similarly, NHB females are less likely to smoke but have comparable lung cancer rates to NHW females. We use a multistage carcinogenesis model to study the impact of smoking on lung cancer incidence in NHB and NHW individuals in the Multiethnic Cohort Study (MEC).

Background: After accounting for smoking history, lung cancer incidence is greater in African Americans than Whites. In the multiethnic cohort, total nicotine equivalents (TNE) are higher in African Americans than Whites at similar reported cigarettes per day. Greater toxicant uptake per cigarette may contribute to the greater lung cancer risk of African Americans.

Importance: This study aimed to evaluate if there is a difference between outcomes when retropubic or transobturator midurethral sling surgery is performed at the time of colpocleisis.
Objectives: The purpose of this study was to compare the surgical outcomes of the retropubic midurethral sling (RP-MUS) versus the transobturator midurethral sling (TO-MUS) in women who underwent concomitant colpocleisis, specifically 2-year MUS failure and 1-year lower urinary tract symptoms (LUTSs). A secondary aim was to identify factors associated with these surgical outcomes.

Background: A growing literature has reported associations between traffic-related air pollution and breast cancer, however there are fewer investigations into specific ambient agents and any putative risk of breast cancer development, particularly studies occurring in populations residing in higher pollution areas such as Los Angeles.
Objectives: To estimate breast cancer risks related to ambient air toxics exposure at residential addresses.
Methods: We examined the relationships between ambient air toxics and breast cancer risk in the Multiethnic Cohort among 48,665 California female participants followed for cancer from 2003 through 2013.
