We previously showed that higher inflammatory responses are associated with higher tumor incidence in wild‐type mice (23) as well as DNA repair deficient mice including Xpa‐knockout and Ogg1‐knockout mice, both of which are deficient in removing dipyrimidine photoproducts and 8‐oxo‐7,8‐dihydroguanine (oxidatively generated DNA damage), respectively (21, 23, 34). Here, OGG1 is linked to neoplasm.
