In mice, low-dose carbon ion radiation sparked stronger tumor immunity than a much higher x-ray dose.
A low, standard dose of carbon ion radiation can trigger a strong immune attack on tumors. Normally this level of immune response needs much higher doses of regular x-rays. The carbon ions push cancer cells to die in a messy, inflammatory way instead of a quiet way. This messy death alerts the immune system and helps it attack tumors elsewhere in the body, not just the treated spot.
The low carbon ion dose caused more immune-triggering cell death than a much higher x-ray dose.
