A peer-reviewed observational study in Cell looked at a large real-world group of patients with different cancers. It found that most changes in the microbiome were shared across cancers rather than specific to one; an observational study shows a link, not a cause. Distinct links appeared only for some cancers and, in separate analyses, for age of onset and for certain side effects of treatment.

Gut bacteria can worsen stroke via an immune receptor, study finds

A peer-reviewed study in Cell reports that indole-producing Escherichia coli, a gut bacterium, worsens ischemic stroke by activating aryl hydrocarbon receptor (AHR) signaling in immune cells called dendritic cells. Limiting that signaling reduced inflammation in the nervous system and increased regulatory T cells in the meninges, the membranes around the brain. The authors suggest this could be a target for treatment; the abstract does not say whether the work was done in animals or people.
