• U.S. National Toxicology Program (NTP): A $30 million large-scale rodent study reported "clear evidence" of malignant schwannomas in the hearts of male rats exposed to high levels of 2G/3G radiofrequency radiation (RFR), alongside some evidence of brain gliomas and DNA damage in certain tissues.

• Ramazzini Institute: A large rodent study mirrored findings from the NTP, observing similar heart and brain tumor increases at lower exposure levels that closely mimic environmental cell tower exposures.

• Cellular and DNA Research: Multiple in vitro and animal studies (including reviews indexed via PubMed) suggest that RF radiation can increase oxidative stress, trigger cellular inflammation, or cause single- and double-strand DNA breaks under specific experimental conditions.

Here are two studies, one from the National Cancer Institute and the other from the National Institute for Health.
