I think the point is that you likely won't do all of those things all day every day; rarely do you spend all day and night in the sun, drinking coffee every hour, and eating red meat 3 times a day.
Your phone is with you at all times of the day, always within 5 feet of your person, which means that if it leads to cancer (which we will likely find out within the next 30 years since American children are now surrounded by phones and tablets from age 5) then it's much more likely that you end up with cancer because of your phone rather than the fact that you were out in the sun for an hour every day.
The first iPhone was released in 2007. Radars have been used since WW2. Of course it's theoretically possible that cell phone radiation causes cancer to everyone but only after being largely ineffectual for 12 years of continuous use, but that's somewhat reaching, IMHO.
