Nature never ceases to disappoint when it comes to combating diseases, even deadly ones like cancer. In Japan, a groundbreaking study was published last December but not widely reported and went virtually unnoticed – that is until now when it has been shared on X by epidemiologist and health expert Nicolas Hulscher and featured in the Jimmy Dore podcast.
The study by Japanese researchers was published in the journal Gut Microbes (Volume 17, 2025, Issue 1). It studied the effect of 9 different strains of bacteria found in amphibians on cancerous tumors. One of these bacteria called ewingella americana (or E. Americana for short), which is found in the gut of the Japanese tree frog, had remarkable ant-tumor effects when administered to mice having cancerous tumors. Hulscher explains concisely what the bacteria did to the tumors.
A SINGLE dose of a newly discovered frog gut bacterium ELIMINATES 100% of cancerous tumors within just a few days in mice.
A new landmark study found the natural bacterium Ewingella americana selectively targets, colonizes, and terminates tumors—with NO detectable toxicity.… pic.twitter.com/puq5e6rEtU

This study has invaluable potential for end of cancer in humans if it provides the same results in humans with cancer. The fact that no negative effects or health risks were found with this bacteria as it caused the end cancer in mice speaks for its eligibility as a potential cancer treatment.
Now the hard part is whether big pharmaceutical companies that make billions off their cancer treatments would allow naturally occurring bacteria to be turned into potential cancer cure. Past experiments on groundbreaking cancer cures have been derailed through defunding, intimidation, or other underhand tactics.
