> No evidence is needed. Tissue damage is damage and genetic stress. It can increase the risk of a local cancer.
"No evidence needed" works if you want to be an astrologer.
Then everything causes cancer (and death really) by means of break, bruise, bump, burn, cut, prick, sprain, tear, etc.
Where evidence is needed is if you want to show a statistically significant result of your analysis that something indeed causes injury, and does it often enough to cause cancer within a person's lifetime.
The healing of repeated damage to the body is a vector for cancer. For example, mesothelioma caused by asbestos. The asbestos is continuously damaging tissue in the body, and the healing of said damage leads to calcification of tissue and potentially cancer.
It's certainly possible that other repeated tissue damage, such as those from burns, could also be cancer causing.
..let’s assume that a specific area of our inner body is “micro-cooked” constantly, the body will certainly try to repair that area with higher frequency and therefore there would be a higher risk of cancer, wouldn’t it?
I guess we should consider heated seats dangerously carcinogenic then. They put out far more power than a cellphone. Same with heating bags and homes without air conditioning.
I use shorter or higher wavelengths (depends on the channel in question) to cook my food every day but my phone sure doesn't emit 700W
