Supposing cellphones cause cancer, why is it that radiation treatments shrink the tumor ?

Scientific basis: Cell phones don't cause cancer. This is something that's been kept alive by politicians, fear-mongers, and retrospective (basically junk) studies. In the big study a decade ago, more people had brain cancer on the opposite side. Radiation therapy works by several mechanisms, causing cancer cells (which are wimps) to self-destruct or fail to divide.

Radiationis anti DNA: Radiation in the proper doses can destroy the dna of a tumor cell which is more sensitive than that of normal cells. The frequency of cell phone radiation is not in the same range as gamma radiation.
