What is the most important thing to beat câncer?

The most important avenue for improving cancer treatment is immunotherapy—especially engineering T cells to recognize and attack cancer more effectively. Immunotherapy redirects the immune system toward cancer: checkpoint-inhibitor drugs can release natural “brakes” on T cells, while engineered CAR T cells are programmed to seek cancer targets. The longer-term goal is to make T cells even better at recognizing tumors and resisting the ways cancers evade immune attack. 1 2

• Immunotherapy: It uses the immune system’s ability to distinguish abnormal cells and attack cancer while aiming to spare healthy tissue. 1
• Immune function with age: Immune function may weaken as people age, potentially contributing to cancer susceptibility. Rapamycin has shown potential to enhance cellular immunity and vaccine response in short-term human experiments, but whether that translates into cancer prevention or treatment is unknown. 3
