Phones cause cancer.?

If it did, we'd all have cancer, right? Radio waves are hitting you from everywhere, everyday, all day --- cell towers, police radio, satellites, TV and radio stations, automatic door openers at stores, and many more. Your cell phone is just one of many.

No more than 1000 other things in the environment that you encounter everyday.

If you believe that, get rid of your cell phone. You are responsible for your own health.

Not long ago a study was completed and cell service 2g-4g cause cancer

There have been studies that confirm both sides of the question. My BIL spent a lot of time driving with one of those headphone ear plug thing and was diagnosed with cancer of the salivary gland on that side of his head. Whether of not the emissions (admittedly Bluetooth) caused it is anyone's guess.

Only in the State of California and possibly Washington

Yes, pretty well documented and worse for children with thinner skulls. Cell phone companies have tried to suppress public awareness of this, but independent studies have corroborated the risk. Corporate profit over humane considerations is what built America , since Industrial Revolution

This matter will never be settled.
Do as you prefer.

i don't think so cuz otherwise i'd be dead long ago.

We don't know, yet. Lots of different sorts of cancer, and of phones.
