Doctors are studying the late effects caused by cancer treatment. They are working to improve treatments and stop or lessen late effects. While most late effects are not life-threatening, they may cause serious problems that affect health and quality of life.

Late effects in childhood cancer survivors may affect the following:
Organs, tissues, and body function.

Thinking, learning, and memory.
Social and psychological adjustment.
