&gt;[A study by the US National Toxicology Program (NTP) exposed large groups of lab rats and mice to types of RF energy used in cell phones. The animals were exposed over their entire bodies for about 9 hours a day, starting before birth and continuing for up to 2 years. The study found an increased risk of rare heart tumors called malignant schwannomas in the male rats exposed to RF radiation, as well as possible increased risks of certain types of tumors in the brain and adrenal glands. However, there was no clear increased risk among female rats or among male or female mice in the study. The male rats also lived longer than rats who were not exposed to RF radiation, for unclear reasons. ](https://www.cancer.org/cancer/cancer-causes/radiation-exposure/radiofrequency-radiation.html)

So only the male rats got more cancer. The mice did not. And the exposed male rats lived longer than the male rats in the control group. 

These tests generally expose the rats to RF over their entire bodies for many hours per day at higher power than a cell phone. Humans don't get whole body RF exposure from cell phones.
