This abstract linking childhood Leukemia to AM radio transmitters does not
define "infantile cancers." As a grandparent of two
infant/toddler boys diagnosed with pre-Leukemic "rare immune
deficiencies" (close proximity to electric meters), I have a problem with
lack of findings re what is defined as "infantile
cancers......"
As with most studies, one must review the entire study
for clarification. Take care - Joanne

The great evolutionary biologist John
Maynard Smith likes saying that "all biology is false," meaning, of
course, that there are very few absolutes in biology...... http://press.princeton.edu/chapters/s7313.html
I would add to that "all epidemiology
is false," meaning, of course, that there are very few absolutes in
epidemiology.......Joanne C. Mueller 6-11-07

Leukemia and
brain cancer patients under age 15 years, along with controls with respiratory
illnesses who were matched to cases on age, sex, and year of diagnosis
(1993-1999), were selected from 14 South Korean hospitals using the South
Korean Medical Insurance Data System. Diagnoses were confirmed through the
South Korean National Cancer Registry. Residential addresses were obtained from
medical records. A newly developed prediction program incorporating a
geographic information system that was modified by the results of actual
measurements was used to estimate radio-frequency radiation (RFR) exposure from
31 amplitude modulation (AM) radio transmitters with a power of 20 kW or more. A
total of 1,928 leukemia patients, 956 brain cancer patients, and 3,082 controls
were analyzed. Cancer risks were estimated using conditional logistic
regression adjusted for residential area, socioeconomic status, and community
population density. The odds ratio for all types of leukemia was 2.15 (95%
confidence interval (CI): 1.00, 4.67) among children who resided within 2 km of
the nearest AM radio transmitter as compared with those resided more than 20 km
from it. For total RFR exposure from all transmitters, odds ratios for
lymphocytic leukemia were 1.39 (95% CI: 1.04, 1.86) and 1.59 (95% CI: 1.19,
2.11) for children in the second and third quartiles, respectively, versus the
lowest quartile. Brain cancer and infantile cancer were not associated with AM
RFR.
