Can you tell me if cell phones cause brain cancer/tumors?

No: Somebody may tell you this is "still under study", but this pathologist thinks the idea is just wrong. No theoretical mechanism. You can find that anything causes anything if you do a bad study or ask the wrong questions, especially retrospectively. In one big study, the tumors were more common on the side opposite the cell phone. Stop worrying and enjoy the benefits of today's technology.

Cell phone use: Cell phone radiation is low-frequency & low energy. It is actually nonionizing radiation. Unlike high frequency wave ionizing radiation, it is doubtful it can cause cancer in humans. Cell phone radiation was however, shown to ^ risk for developing schwannomas in rats & gliomas in other animal studies. REF: https://www.mskcc.org/blog/do-cell-phones-cause

Can cell phones cause cancer, brain tumors, etc?

Controversial: There is very little evidence that cell phone usage causes brain tumors. At least one large study in (i think) sweden suggested a slight increase in the frequency of tumors or the 8th (acoustic) nerve in high-use individuals, but showed no increase in other types of brain tumors, including gliomas. Other studies have not even supported that there are more 8th nerve tumors from cell phones.

U.S. C.D.C. says...: In the last 15 years, hundreds of research studies have investigated whether health problems can be linked to cell phone use. Some of these studies have suggested the possibility that long-term, high cell phone use may be linked to certain types of brain cancer. These studies do not establish this link definitively. Scientists need to conduct more studies to learn more about this possible risk.

Variable: Location and tumor size typically determine how a brain tumor will present. People can have seizures, headaches or even focal neurologic problems (similar to a stroke) such as blurred vision, weakness or difficulty speaking.

No real answer: No on knows what really causes malignant brain tumors. There are clearly genetics which can be part of the story. There are probably also linkages to environmental exposures, etc....But not have been teased out. There's been a lot of stories about cell phone use....But that has never really been shown to be linked to tumors - we haven't seen a dramatic increase over the alst 20 years.

Good question: Symptoms can be varied depending on location, size and tumor. Tumors in the posterior fossa can cause balance, nausea, vomitting, headaches. Tumors in the supratentorial area can cause weakness, seizures, speech, word finding, sensory loss etc.
