Many diseases related to bacteria, such as inflammatory bowel disease or colorectal cancer, are associated with an overgrowth of gut bacteria considered 'bad'.

By 2050, there will be more than 35 million new cases of cancer worldwide, an increase of 77% from the 20 million cases reported in 2022. These are projections made by the WHO's International Agency for Research on Cancer (IARC), which has published the latest estimates of the global burden of cancer. Using data from 185 countries, IARC estimates that in 2022 lung cancer was the most common cancer worldwide, with female breast cancer in second place, followed by colorectal, prostate and stomach cancer. The authors stress the urgent need to address inequalities around these diseases.
