“…Compared to population counterparts, risk of later stage prostate, breast or colorectal cancer diagnosis was not found in Californian Hispanic farmworkers; nor for colorectal cancer stage in French farm men and women. 14,16 Findings in our study were similar to these cohorts for women, although slightly different for men. However, compared to our study, the French and Californian cohorts were younger and defined by occupation not residence.…”

“…11,12 International studies have generally reported reduced cancer risk in farmers compared with others for breast and colorectal cancers, with mixed results for prostate cancer. [13][14][15] Stage at diagnosis has only been reported in two cohorts involving farmers in the international literature. 14,16 This study will examine if stage at diagnosis differs between farm, rural non-farm and urban residents for prostate, breast and colorectal cancers in the 45 and Up cohort.…”

Objective: To determine if stage at diagnosis of prostate, breast and colorectal cancers differs between farm, rural non-farm and urban residents. Design: Data linkage of baseline survey information from a large cohort study, with state cancer registry records from 2006 to 2009. Setting: New South Wales, Australia. Participants: New South Wales residents enrolled in the 45 and Up Study cohort. Main outcome measures: Adjusted odds ratio of nonlocalised cancer stage was modelled using binary logistic regression, controlling for commonly known cancer risk factors. Results: Overall differences in the odds ratios for later stage prostate, breast and colorectal cancer diagnosis in farm men and women compared with rural nonfarm and urban counterparts were not statistically significant, although farm men had twice the odds of either group of being diagnosed at later stage colorectal cancer. The odds of later stage prostate cancer for farm and urban men were similar, but rural non-farm men were significantly less likely than urban men to be diagnosed at later stage. Higher household income was associated with later stage breast and prostate cancer; and private health insurance with extras was negatively associated with later stage prostate cancer.Conclusions: Differences in stage of cancer diagnosis, particularly between farm and rural non-farm men, remain unexplained but were not statistically significant. Farm men may be at higher risk of later stage colorectal cancer diagnosis, which if confirmed has implications for research on possible reasons, and for the delivery of appropriate cancer diagnostic services in rural areas.

“…A study among Mexican Latinos in Texas identified associations between exposure to agrichemicals, being US-born, lack of physical activity and PC family history and higher risk of PC [ 54 ]. This finding is supported by the observation that California farm workers, which are predominantly Mexican migrant workers, showed disproportionately more PC cases than Californian NHW [ 55 ]. Diets high in red meat have been proposed to increase PC risk, and an association between red meat cooked at high temperatures and risk was reported among Latinos in a multi-ethnic study [ 56 ].…”

Variability in Cancer Risk and Outcomes Within US Latinos by National Origin and Genetic Ancestry

Latinos have lower rates for most common cancer sites and higher rates of some less common cancers (gallbladder, liver, gastric, and cervical) than other ethnic/racial groups. Latinos are a highly heterogeneous population with diverse national origins, unique genetic admixture patterns, and wide spectrum of socio-demographic characteristics. Across the major cancers (breast, colorectal, prostate, lung, and liver) US-born Latinos have higher incidence and worse survival than foreign-born, and those with low-socioeconomic status have the lowest incidence. Puerto Rican and Cuban Latinos have higher incidence rates than Mexican Latinos. We have identified the following themes as understudied and critical to reduce the cancer burden among US Latinos: (1) etiological studies considering key sources of heterogeneity, (2) culturally sensitive cancer prevention strategies, (3) description of the molecular tumor landscape to guide treatments and improve outcomes, and (4) development of prediction models of disease risk and outcomes accounting for heterogeneity of Latinos.

“…Similarly, an analysis on members of the United Farm Workers of America in California from 1973 – 2000 found farmers to be at reduced risk for lung cancer [37]. In a study assessing cancer risk in California farm workers from 1988 – 2010, less lung cancer was found in farm workers compared to a non-Hispanic white population assessed [38]. On the other hand, a study comparing farmers to non-farmers in the Province of Vercelli in Italy, farmers had increased risk of numerous cancers including lung cancer (OR = 1.59), with males having a higher lung cancer risk than females [39] The AGRICAN cohort study from France summarizing data collected from 2005 – 2009 reported no significant changes in lung cancer risk for farm owners and agriculture workers [40].…”

Purpose of review Occupational exposures in the agricultural industry are associated with numerous lung diseases, including chronic obstructive pulmonary disease, asthma, hypersensitivity pneumonitis, lung cancer and interstitial lung diseases. Efforts are ongoing to ascertain contributing factors to these negative respiratory outcomes and improve monitoring of environmental factors leading to disease. In this review, recently published studies investigating the deleterious effects of occupational exposures in the agricultural industry are discussed. Recent findings Occupational exposures to numerous agricultural environment aerosols, including pesticides, fungi, and bacteria are associated with impaired respiratory function and disease. Increases in certain farming practices, including mushroom and greenhouse farming, present new occupational exposure concerns. Improved detection methods may provide opportunities to better monitor safe exposure levels to known lung irritants. Summary In the agricultural industry, occupational exposures to organic and inorganic aerosols lead to increased risk for lung disease amongst workers. Increased awareness of respiratory risks and improved monitoring of agricultural environments are necessary to limit pulmonary health risks to exposed populations.
