Aswell as infection, the imbalance of the microbiome can lead to carcinogenesis (Schwabe, R.F. & Jobin, C. 201). Liver and pancreatic cancer can be caused by the imbalance of the microbiome in the intestine (Schwabe, R.F. & Jobin, C. 201). An imbalance in the microbiome

I had no idea that bacteria could cause cancer. Do medical professionals worry about the bacteria causing cancer, or is it mostly just the infection they are concerned about?
ReplyDeleteSorry I’m a bit confused …are you saying that our microbiomes may sometimes turn against and cause cancer, but that this is a trade-off because the bacterium that can cause gastric cancer helps prevent oesophageal cancer? If so, does this mean that the incidence of oesophageal cancer is much higher than gastric cancer, which could be why we rely on this bacterium?
