Objective:
To evaluate cancer incidence overall and renal cancer in particular among workers at the Valley Forge satellite manufacturing complex in Pennsylvania. A previous mortality study observed a slightly elevated risk estimate for brain cancer.
Methods:
A cohort of 27,586 workers, employed between 1962 and 2008 and alive in 1990 when cancer follow-up began, was investigated. Standardized incidence ratios (SIRs) were calculated.
Results:
A total of 4303 incident cancers were diagnosed. The SIRs were significantly reduced for all cancers (0.88; 95% confidence interval [CI], 0.85 to 0.90) and several site-specific cancers. The renal cancer SIR was 1.00 (95% CI, 0.84 to 1.19) and the brain cancer SIR was 1.17 (95% CI, 0.90 to 1.49).
Conclusions:
This cancer incidence study of satellite manufacturing workers found no convincing evidence of increased cancer risk overall, or for renal or brain cancer in particular.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
