We found no high-quality evidence that suggests that Wi-Fi is associated with a higher risk of brain cancer or any type of cancer.
Some in-vitro cell studies reported possible effects of radiofrequency from Wi-Fi in the metabolism or growth of colorectal cancer, prostate, and breast cancer
However, theWorld Health Organization, the National Cancer Institute, the Government of Canada and the Government of the United Kingdom guidelines report that radio frequency exposures from Wi-Fi are likely lower than those from mobile phones, and cause no health risks.
There is no consistent evidence to date that exposure to radio signals from Wi-Fi adversely affects the health of the general population.

Opinions alone are not a reliable basis for claims about the effects of treatments.
Just because someone in authority makes a treatment claim, you cannot be sure that it is trustworthy unless it is clearly based on a summary of fair comparisons.
Always ask yourself whether the possible advantages of treatment outweigh the disadvantages of the treatment.
