What We Do

The Cancer Prevention and Survivorship team is part of the Population Science Department. We conduct research to identify risk factors associated with developing cancer and to understand how to improve quality of life and survival after a cancer diagnosis. We do much of this work using our large, longitudinal cohorts the Cancer Prevention Studies (CPS) and Studies of Cancer Survivors (SCS). 

Since 1952, when the first of our cohorts was formed, we’ve enrolled over 2.7 million people who routinely answer surveys and have also provided blood and other biological samples such as tumor tissue samples from after a cancer diagnosis.

Collectively, our Cancer Prevention Studies and Cancer Survivor Studies have provided data for hundreds of scientific publications by our research staff and researchers across the world. Additionally, these studies help inform clinical and public health guidelines, including the American Cancer Society's Nutrition and Physical Activity guidelines.

Data from these studies have helped us better identify and understand the role of lifestyle behaviors, medical history, environmental exposures, genetics, metabolomics, and other biological factors on the risk for developing cancer and on survival.

Specifically, we study the influence of:

  • Nutrition
  • Physical activity and sedentary behavior
  • Obesity
  • Health care access and equity
  • Environmental carcinogens
  • Tobacco and tobacco cessation
  • Mental health
  • Social support processes
  • Caregiving and support of caregivers
  • Genomics
  • Metabolomics

Key Terms

  • Epidemiology: The study of the occurrence, distribution, and possible causes of diseases (like cancer) in a group of people.  
  • Prospective Cohort Study: A long, on-going (longitudinal) research study that captures and compares years of data from a group of people (cohort) to learn how specific characteristics or risk factors affect the rate of developing diseases such as cancer.  Prospective means data is collected before anyone has developed cancer. Cohort studies are a type of observational study.
  • Observational study: When researchers observe the effect of a risk factor, diagnostic test, treatment, or other intervention without trying to change who is or isn't exposed to it. 
  • Experimental study: When researchers introduce an intervention and study the effects. Randomized controlled trials are a type of experimental study.
  • Human Genomics: The study of a person’s genome—a complete set of DNA, including all of its genes.
  • Metabolomics: The study of small molecules, called metabolites, that are made and stored when the body breaks down food, drugs, or its own tissue and that are affected by the environment and diseases like cancer.

Our Cancer Prevention and Survivorship Work

The data we collect from our longitudinal studies helps answer important questions about the causes of cancer, how to help prevent it, and how to help people survive their cancers to lead long and healthy lives.

ACS Cancer Prevention Studies

Throughout the more than 50 years that we’ve collected data through our large, prospective Cancer Prevention Studies (CPS), we’ve been able to help answer key questions about why some people develop cancer and others do not.

We’ve published groundbreaking cancer prevention research that’s identified new risk factors for cancer and helped us understand the influence of family medical history and genetics in the development of cancer. The potential to find more answers continues with each year’s new data.

We thank the millions of people who have participated in these cohorts, and who participate today. With your help, we continue to move closer to a world without cancer.

Survivorship and Quality of Life Research

The population of cancer survivors continues to grow as more and more people live for years after learning they have cancer.

Using information collected from cancer survivors, physicians, and caregivers through studies like the ACS Studies of Cancer Survivors (SCS) and others, we study the physical, emotional, and social effects before, during, and after treatment. This research helps us to understand life after a diagnosis of cancer for survivors and their caregivers.

Additionally, our findings inform the development of ACS programs that offer support to cancer survivors, their communities and caregivers, and their health care providers.
