"I am convinced that it is caused by holding cell phone"

Unlikely once you understand the science. You need high energy, ionizing, radiation to cause cancer. It needs to carry enough energy rip electrons from their atoms. Gamma rays, x-rays, UV-C and some UV-B can do this. Below that there isn't enough energy carried to damage an atom: visible light, microwaves, and even less energy in the RF waves from a cell phone.

So maybe there is some mechanism we don't understand yet, but there is neither empirical evidence to support the effect, nor is there a scientific reason to think it would.

See #45. Glioblastoma not located to one brain region anyway and some common locations are far from where a phone is held.

So you’re an “expert?”

Like the “experts” that gave us PCR false-positives, masks, lockdowns and fake “vaccines” for a virus no more deadly than the common flu?
