Are there health dangers to having so many cell phone towers and wi-fi connnections everywhere?

I’m not a conspiracy theorist, but I’ve been reading about 5G, which will require many more cell phone towers spaced closer together and it sounds a bit concerning to me. In 2017, a scientific study about the carcinogenic effects of RF/EMF exposure to humans was submitted to the EU. We know that more people are getting cancer than ever before. Can there be downside to this advance in technology?
