It’s no secret that most of us are addicted to body odor.
And now, thanks to new research from the University of Toronto, it appears that the same chemical we associate with body odor also plays a role in the development of cancer.
“For decades, researchers have speculated that odor could play a role on cancer development, but until now, no research has directly linked odor with disease progression or survival,” said senior author and associate professor of medicine at the University’s Department of Pathology and Toxicology, Dr. Michael Fauci.
“Our research is the first to provide direct evidence that the development and survival of cancers depend on the chemical composition of a person’s microbiome.”
“Our study indicates that the body’s microbiome may play a crucial role in developing the disease state of a cancerous tumour,” said Dr. Faucs, who is also the chair of the department of pathology and toxicology at the university.
Using a combination of gene sequencing and molecular biology, Fauces team identified a set of genes that are located on specific bacterial chromosomes, and then used a variety of molecular and genetic tools to analyze their expression in the colon, liver, lung, pancreas, kidney and thyroid.
Their findings show that the genetic and epigenetic components of the bacterial microbiome are key to shaping the disease process.
“In particular, we found that certain bacterial DNA regions were highly enriched in genes associated with disease, such as tumor necrosis factor alpha, which we describe as a hallmark of the disease,” Dr. Fauci said.
The findings, which were published in the journal Science, provide evidence that these genes play a key role in cancer progression and survival.
Specifically, the scientists found that high-level genes associated to the development, progression and metastasis of the cancer were more abundant in people who had more than 20 bacteria.
This finding suggests that these high-functioning genes may be essential to the normal growth and maintenance of the microbiome.
Dr. James Faucci is a professor of pathology and toxicological sciences at the School of Medicine and Health Sciences at the Université de Montréal.
He is also co-author of The Origins of Cancer and The Evolution of Cancer. More from Breitbart News:
