A new study finds that adolescent and young adult cancer survivors age faster than people who never had cancer. Researchers saw signs of faster biological aging and changes in brain function that affect memory and attention.
The study included about 1,400 patients who were at least five years after treatment. Most had acute lymphoblastic leukemia or Hodgkin lymphoma. Results showed chemotherapy sped up aging fastest. For those who had radiation to the brain, researchers want to stop problems from getting worse. Teams are testing quitting smoking, exercise and better nutrition as ways to help.
