Obesity represents a risk factor for cancer and compromises immune function, however the mechanisms linking the two together are not fully known. Here authors show in a mouse sarcoma model that obesity increases tumour incidence, impairs intra-tumoral T cell immunity but paradoxically increases sensitivity to immune therapy via impairing immunoediting.
