Abstract

Generational Risk of Colon and Rectal Cancer in Recent Birth Cohorts under Age 40 - the Hypothetical Role of Radiofrequency Radiation from Cell Phones Devra L Davis, Aaron M. Pilarcik, Anthony B. Miller. Generational Risk of Colon and Rectal Cancer in Recent Birth Cohorts under Age 40 - the Hypothetical Role of Radiofrequency Radiation from Cell Phones. Ann Gastroenterol Dig Dis, 3(1): 09-16. 2020. Abstract To determine if there are shifts in patterns of cancer, rates of disease can be evaluated in terms of Generational Risk (GR), comparing those born recently with those born decades earlier. Using data from the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Surveillance Epidemiology and End-Results (SEER) Program and Iranian cancer registries, increases in GR of colon and rectal cancer in those under age 50 are presented. For the U.S. those born in the 1990s have a doubled risk of colon cancer (GR=2) and a fourfold increase in rectal cancer (GR=4) by the time they reach age 24 compared to those born six decades ago. Experimental studies have determined that the colon and rectum of Sprague-Dawley rats are exquisitely sensitive to both ionizing and non- ionizing radiofrequency radiation (RFR), expressing significant differences in patterns of methylation of a number of well-identified proteins and other biomarkers predictive of cancer risk. Modeling of nonionizing exposures also indicates that absorption of RFR into the colon and rectum from cell phones stored in the pocket exceeds current test limits by up to 5-fold. French government tests of phones positioned next to the body report exposures to non-ionizing radiation that are up to 11 times more than current guidelines. Based on these findings, it is prudent to develop policies to reduce direct exposures to RFR from cell phones, as occurs when they are kept next to the body, and to promote advances in hardware and software that reduce direct exposures to RFR.

Main findings

Using CDC/SEER and Iranian registry data, the authors report increased generational risk of colon and rectal cancer in younger birth cohorts (e.g., U.S. 1990s birth cohort GR=2 for colon cancer and GR=4 for rectal cancer by age 24 vs those born six decades earlier). The paper cites experimental rat studies reporting biomarker/methylation differences after radiofrequency radiation exposure and cites modeling and French phone tests suggesting higher-than-limit/body-adjacent exposures; it argues these findings support policies to reduce direct cell-phone RF exposure when kept next to the body.

Outcomes measured

  • Colon cancer incidence/generational risk
  • Rectal cancer incidence/generational risk
  • Biomarkers/methylation patterns predictive of cancer risk (in rats)
  • Modeled RF absorption into colon/rectum from phones stored in pocket
  • Phone RF exposure levels in French government tests vs guidelines

Limitations

  • Appears to be a hypothesis-driven narrative linking cancer generational risk trends to cell-phone RF exposure rather than a direct epidemiologic test of RF exposure and colorectal cancer risk.
  • No quantitative details provided on exposure metrics (frequency, SAR, duration) or on the underlying registry sample sizes in the abstract.
  • Includes animal/biomarker and modeling/phone-test evidence alongside human incidence trends; causal inference for humans is not established in the abstract.
