Voluntary exercise influences metastatic organotropism in a murine colorectal cancer model

Physical activity is associated with a lower risk of colorectal cancer (CRC) and CRC‐specific mortality. However, evidence for a causal relationship between physical activity and disease progression is lacking. Here, we have used CRC organoids to create a novel mouse model for spontaneous metastasis formation to multiple organs. We have used this model to assess the influence of voluntary exercise on disease progression.
