Looking at causes of cancer first.
There is a new toxin that many people are now exposed to that can cause all forms of cancer.
MICROWAVE RADIATION from cordless landlines and WiFi and cell towers, etc
People need to cable up all wireless devices and shield from high beams from neighbours.
Cancer develops from 5 to 15 years of current exposures if these devices are in the house.
The radiation also acts as a catalyst for other toxins like chemicals.
