This is pretty easy. After 2010 is when smartphones and data-heavy apps exploded. Everyone has a emf transmitter in their pocket less than 12 inches from their colon for 10+ hours of the day, every day, pulsing according to the chronic transmission activity of every running app. It's not the electric but the magnetic field component that is doing the damage to the biology. The tissue in the gut is most susceptible so it shows this pathology more readily than other tissue. If you wait long enough you'll see an uptick in overian/testicular cancer, and then later bone cancer in the pelvis/femur.

Even conspiracy newbs know about the prevalence of head tumors (brain, lymph, salivary, etc) that became prevalent as the antennas in cellphones were miniaturized. Old story, more pulses, more sheep, different body part.
