That only accounts for ionization which is the most common way of damaging cell tissue and most importantly DNA through the breaking down of molecular bonds.

However other effects can also cause biological processes to differ or fail for example heat e.g. boiling an egg.

Now I’m not saying that the radiation form a cellphone can cook you but we don’t have a clear understanding of how non-ionizing radiation affects all biological processes such as protein folding but we know that it does:

The fact that nonionizing radiation can affect biological processes has been well documented and is being studied.

Again this doesn’t mean that cellphones cause cancer or any other harm but you really don’t need new physics for them do so.
