There is a correlation between the rising number of cancer cases and the rapid spread of cell phone use. Cell phones first began to become widely available to consumers in the 1990s, growing to over 5 billion cell users by the late 2010s. Over roughly the same time period, from 1990 to 2017, the number of cancer deaths globally increased by 66%. These trends are exactly what would be expected if cell phone use was causing increased cancer risk.
Correlation does not mean causation. There is no concrete proof that increased cancer rates are caused by radiation emitted by cell phones.
[P1] As cell phone use has risen, so have cancer rates. [P2] Cell phones must be causing the increase in cancer rates.
Rejecting the premises
[Rejecting P2] There's no real proof that cell phone use is responsible for cancer rates.
