original passage: The World Health Organization has classified radio frequency electromagnetic radiation as Group 2B - possibly carcinogenic. This group contains possible carcinogens such as lead, DDT, and styrene. For example, epidemiological studies looking for a relationship between cell phone use and brain cancer development, have been largely inconclusive, save to demonstrate that the effect, if it exists, cannot be a large one.

sentence2: Although it would be highly misguided to assume causation from correlation, could someone reading this passage get the idea that cell phones might actually slow down the growth of cancer cells in the human brain that would otherwise have come about from some other cause?
