While ultra processed foods can definitely be an influential factor in the rise of cancers, it doesn't explain the sudden explosion in all types of cancers suddenly around 2021. People have been eating this crap since the 80s when food started to change.

My wife sees the top preventative oncologist in our region. He got 2 jabs before he realized the effects of the jab. His large practice has seen an explosion in these cancers, both novel and turbo. He became staunchly anti-COVID vax and "they" tried to blackball him, up to threatening his license and practice if he didn't stop doing interviews. Every time my wife sees him (2X/yr) his position, based on empirical and observational data, is further entrenched that the more shots you get, the higher the cancer risk.
