Introduction

Millions of Americans are living with a diagnosis of cancer*. This National Cancer Institute (NCI) booklet (NIH Publication No. 06-1566) has information about this disease. You will read about possible causes, screening tests, symptoms, diagnosis, and treatment. You will also find suggestions for coping with cancer.

Researchers are learning more about what causes cancer, and how it grows and progresses. And they are looking for new and better ways to prevent, detect, and treat it. Researchers also are looking for ways to improve the quality of life for people with cancer during and after their treatment.
