So what's the current speculation on how it causes cancer?
Glyphosate acts on the Shikimate pathway that doesn't exist in humans.
Is it killing gut bacteria?
My theory is that if you torture a chemical with enough diverse studies, you can find some where it confesses to causing cancer, even if it actually doesn't.
Human gut bacteria have the Shikimate pathways so it can kill them.
Basicaly glyphosate could act like a gut bacteria antibiotic.
>> 54% of the human core gut bacterial species are potentially sensitive to glyphosate, which targets an enzyme in the shikimate pathway, suggesting that roughly half of gut bacteria possess this pathway

Mechanistic evidence shows low doses cause genotoxicity and oxidative stress in human lymphocytes and other cells.
A novel mechanism proposal is that glyphosate may chelate and accumulate in the bone, slowly releasing into the bloodstream, exposing bone marrow and potentially triggering hematologic malignancies.
