Self-inflicted DNA breaks let the cells hit pause on repair of radiation-induced DNA damage, giving them time to recover, an in vitro study shows.

The immune cells facilitate healing, but they may also help tumors metastasize to the lungs after injury, a study in mice finds.

In a retrospective analysis, a team found that an algorithm integrating the gene expression of a tumor with the radiation dose a patient received predicted how well the patient responded to the treatment.

Depleting intestinal fungi allows radiation to effectively fight cancer, likely because the microbes influence the antitumor immune response.

Scientists make oxygen-filled microbubbles designed to increase tumor sensitivity to radiation.

Researchers use bacteria to deliver radiation to shrink pancreatic tumors in mice.
