'Smartphones increase your risk of CANCER'

Question

This claim that cell phones cause cancer is false. This article by the Daily Mail says "Using a mobile phone for as little as 17 minutes per day over 10 years increases the risk of developing cancerous tumors by up to 60 percent, a surprising study found." This is a wild claim that is not backed by any factual evidence and a report from The National Cancer Institution debunks that by saying there is no evidence in their extensive research to prove that cellphones have any correlation to cancer or tumors. https://www.cancer.gov/about-cancer/causes-prevention/risk/radiation/cell-phones-fact-sheet

Answer 1

Although cellphones do emit radiation, the frequencies of radiation are not high enough to damage cells.  

Cellphones do not emit ionizing radiation like x-rays or radon, which do damage cells.  

The only noticeable effect cellphones have on the human body is warming the area where the cellphone is.  For example, your hand, your pocket, next to your ear.  However, this does not lead to an overall change in core body temperature.

Answer 2

According to the National Cancer Institute as of April of this year, there is no correlation between smartphone usage and developing brain or nervous system cancer.

Cell phone radiation corresponds to the electromagnetic spectrum's radiofrequency section, giving off amounts of non-ionizing radiation too small to harm human DNA. The only understood effect of radiofrequency waves emitted by cell phones is warming areas of the body in contact with a device. 

Notably: the most extensive case-control study ever conducted to examine causation between smartphone use and neck and head tumors presents a possible contradiction.The study's subjects and researchers spanned thirteen countries. It found a positive correlation "between intracranial distribution of tumors within the brain and self-reported location of the phone." However, the study authors asserts that a causal association was indeterminable based on the researchers' discoveries.

Answer 3

The claim that smartphones cause cancer is false. The National Cancer Institution explains that there is not enough evidence of data that says that smartphones cause cancer. The FDA states "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.", which then leads to them saying that even after 30 years of research they have not linked smartphones being the cause of cancer. Lastly, American Cancer Society have done studies that radio frequency waves don't have enough energy to hurt and damage our DNA or even to hurt our body tissue. 

These 3 sources have consistently provided studies that there either hasn't been enough data to prove that smartphones directly cause cancer, and they even through studies, smartphones are not the leading cause of cancer in humans.
