Thanks, Pam!.
One of the studies mentioned linked to Lancet,

which has a collection of other studies, one being this:
Cell Phone Radio Frequency Radiation
Final reports from the rat and mouse studies, plus the press release and fact
sheet, are now available.
Cell phone
Research Overview
Status: Completed
Substances: Cell Phone Radiation: GSM, Cell Phone Radiation: CDMA
Nominated: May 1999
BACKGROUND INFORMATION
Cell phones are currently used by 95% of American adults. The U.S. Food
and Drug Administration (FDA) nominated radio frequency radiation (RFR)
used by cell phones for an NTP study because of widespread public use of
cell phones and limited knowledge about potential health effects from long-
term exposure.
NTP STUDIES & FINDINGS
NTP conducted two-year toxicology studies in rats and mice to help clarify
potential health hazards, including cancer risk, from exposure to RFR like
that used in 2G and 3G cell phones which operate within a range of
frequencies from about 700–2700 megahertz (MHz). These were published
as Technical Reports in November 2018.
What did the studies find?
NTP uses a standard scale (graphic of NTP’s Level of Evidence Rating
System for Cancer Studies) to determine the strength of the evidence for an
association between the exposure and findings in the tissues or organs
studied. The scale ranges from the highest rating of “clear evidence,”
followed by “some evidence,” then “equivocal evidence,” and finally “no
evidence.” Different organs or tissues can have different conclusions.
The NTP studies found that high exposure to RFR (900 MHz) used by
cell phones was associated with:
Clear evidence of an association with tumors in the hearts of male rats. The
tumors were malignant schwannomas.
Some evidence of an association with tumors in the brains of male rats. The
tumors were malignant gliomas.
Some evidence of an association with tumors in the adrenal glands of male
rats. The tumors were benign, malignant, or complex combined
pheochromocytoma.
It was unclear if tumors observed in the studies were caused by exposure to
RFR in female rats (900 MHz) and male and female mice (1900MHz).
As a follow-up, NTP published an article in October 2019 that evaluated
DNA damage in three regions of the brain, the liver, and in blood cells in rats
and mice that were removed at an earlier timepoint from the ongoing 2-year
toxicology study. DNA damage, if not repaired, can potentially lead to
tumors. This work was also included in NTP’s published Technical Reports,
but this study includes analyses of the data in the supporting information
not included in the Technical Reports.
NTP scientists found that RFR exposure was associated with an increase
in DNA damage. Specifically, they found RFR exposure was linked with
significant increases in DNA damage in:
the frontal cortex of the brain in male mice,
the blood cells of female mice, and
the hippocampus of male rats.
There are many factors that influence whether damaged DNA will lead to
tumors. NTP plans to conduct additional studies to learn more about how
RFR might cause DNA damage. Please see the FAQs below for more
information about the specific studies and NTP’s cell phone RFR program.
What are NTP’s future plans for studying cell phone RFR?
