Radiotherapy against prostate cancer may cause very serious intestinal side effects and only a few studies have investigated the impact of the local microbiota.

Now, Miguel Reis Ferreira and colleagues from the Institute of Cancer Research in London, UK, analyzed the bacterial differences between the microbiome of patients suffering from radiotherapy side effects and the microbiome of those who do not suffer from them.

We discussed the research findings with Ferreira in Milan during MIBIOC, the first international congress dedicated to the relationship between microbiota and cancer.
