Cancer Prevention: You Can Help

The following information is borrowed from the American Cancer Society's website and is used with permission.  

There are nearly 13.7 million people in America who have survived cancer, and the increasing number of survivors each year is due in large part to ongoing research being performed around the world. Many of you may make monetary gifts to organizations that support cancer research, but did you know there is another way you can help prevent cancer in future generations?

The American Cancer Society's Epidemiology Research Program is inviting men and women between the ages of 30 and 65 years who have no personal history of cancer to join an historic research study - the Cancer Prevention Study 3 (CPS-3). The ultimate goal is to enroll at least 300,000 adults from various racial/ethnic backgrounds from across the U.S. By joining CPS-3, you can help researchers understand how to prevent cancer, which will save lives and give people more of their most precious resource: time.

How Does the CPS Saves Lives?
The American Cancer Society (ACS) first began conducting long-term prospective studies in the 1950s. For these studies, large groups of individuals were recruited through a successful partnership between the ACS researchers and volunteers. The study population provides information (e.g. lifestyle, medical, or behavioral) and then are followed over time to assess their health outcomes and to determine how those outcomes are related to the previously collected exposure data. The commitment of the study participants and the volunteers who recruited them has been vital to the success of these studies.

Past long-term follow-up studies have played a major role in cancer prevention. More than 300 scientific articles by ACS epidemiologists have been published from these studies, significantly contributing to tobacco-related research, and  the understanding of obesity, diet, physical activity, hormone use, air pollution, and various other exposures in relation to cancer and other diseases.

Past American Cancer Society long-term studies include:
Hammond-Horn Study (1952-1955): Included 188,000 U.S. men recruited by 22,000 volunteers. This study was the first large prospective study to examine the effect of cigarette smoking on death rates from cancer and other diseases. This study set the methodologic foundation for the two subsequent Cancer Prevention Studies (CPS-I and CPS-II).

Cancer Prevention Study (CPS)-I (1959-1972): CPS-I included approximately one million men and women recruited by 68,000 volunteers in 25 states. In contrast to the Hammond-Horn Study, CPS-I was designed to address a wide range of potential exposures, in addition to tobacco use, that may increase or decrease cancer risk.

Cancer Prevention Study (CPS)-2 (1982-ongoing): CPS-II includes 1.2 million subjects recruited by 77,000 volunteers in 50 states, Washington, DC, and Puerto Rico. All participants have been followed for over 20 years to determine causes of death. Like CPS-I, this study was designed to address a wide range of environmental and lifestyle exposures that may increase or decrease cancer risk.

CPS-2 Nutrition Cohort (1992-ongoing): 185,000 CPS-II participants from 21 states were enrolled in the new CPS-II Nutrition Cohort, a study designed to better understand how diet affects cancer risk. We periodically mail questionnaires to CPS-II Nutrition Cohort members to update exposure information and follow them for both cancer occurrence and all causes of death. For many members of the CPS-II Nutrition Cohort, biological specimens (blood and buccal (cheek) cells) have also been collected. The CPS-II Nutrition Cohort was designed to address a wide range of potential exposures, behavioral, environmental, and genetic, that may increase or decrease cancer risk.

Results from previous American Cancer Society long-term follow-up studies have demonstrated:
  • The link between cigarette smoking and lung cancer
  • The significant impact of being overweight or obese on risk of cancer occurrence and death
  • The impact of hormones, physical activity, diet, various medications and vitamins, and various other factors in relation to cancer risk
  • The impact of air pollution on cardiopulmonary conditions motivating the Environmental Protection Agency to propose more stringent limits on particulate air pollution
  • the link between aspirin use and reduced risk of colon cancer
  • the link between postmenopausal hormone replacement therapy and various gynecologic cancers (such as breast and ovarian cancer)
  • the link between diabetes and cancers of the pancreas and colon
  • the link between physical activity and lower risk of various cancers (including breast, colon, and aggressive prostate cancer)
Why a New Study?
Because the current study population (CPS-2) is aging, we must recruit a new study population for the next generation of research. Also, the environment and individuals' lifestyles change over time. New follow-up studies like CPS-3 are needed to understand these changes. We will be studying CPS-3 members for the next 20 to 30 years. This younger study population will have environmental and lifestyle exposures that may be meaningfully different from our previous populations and will help us further advance our understanding of the factors that cause or prevent cancer.

Finally, as we improve our understanding of what causes cancer, CPS-3 will allow us to explore new and emerging hypotheses related to cancer. Through this landmark new study, we will continue our work to eliminate cancer as a major health concern for future generations.

In Northwest Arkansas, connect with the ACS through their Facebook page. Study enrollments are currently scheduled in Fort Smith for April 2-3, and in Benton and Washington Counties in September with specific dates TBA.

Will you sign up? Feel free to share this information with everyone you know - the more people who are involved in the study, the more useful the results will be.

Let's Make More Survivors!

Throughout the month of June we've been sharing information about survivorship and what it means to those who are given the title "Survivor" after hearing the words "You have cancer." The journey of cancer is different for everyone. Some consider the journey to be a kind of battle - a war they will either win or lose. Others look at it as just one bump in the road that they will get over and put behind them. For others it is (or becomes) a spiritual journey that causes them to look at their life differently and perhaps rearrange some of the priorities they had pre-diagnosis. And for some, it's a combination of some or all of these, or something completely their own.

No matter what the journey is to each individual, it's safe to say that the desire to become a "survivor" is universal. And for those of us who have been caregivers or who have just been around as a friend or loved-one dealt with cancer treatments, we want to do everything we can to make their journey shorter, easier, and more likely to end with the rest of a long life ahead of them. What if we told you that you have the opportunity to help potentially millions of people not only become survivors, but never be diagnosed at all? It's true... read on.

The American Cancer Society's Epidemiology Research Program is inviting men and women between the ages of 30 and 65 years of age who have no personal history of cancer to join an historic research study. The ultimate goal is to enroll at least 300,000 adults from various racial/ethnic backgrounds from across the U.S. By joining Cancer Prevention Study - 3 (CPS-3), you can help researchers understand how to prevent cancer.

The first version of this study, CPS-1, was the largest prospective mortality study of diseases caused by tobacco use ever conducted. The study, which began in 1959 and continued through September 1972, played a critical role in establishing the causal linkage between smoking and several diseases, and it remains one of the most comprehensive presentations of the disease risks caused by smoking. The laws and regulations currently in place related to advertising and sales of tobacco products are a direct result of CPS-1.

CPS-2 began in 1982 as a prospective mortality study of approximately 1.2 million American men and women. Approximately 77,000 volunteers for the American Cancer Society recruited participants into the study in all 50 states, the District of Columbia, and Puerto Rico. This study is still ongoing.

All voluntary participants in CPS-3 will be required to undergo a simple blood draw, and to complete a detailed questionnaire that will be used as a base-line for your current health and lifestyle. The purpose of CPS-3 is to better understand ways to prevent cancer. This multi-year survey will study lifestyle, behavioral, environmental and genetic factors that may cause or prevent cancer with the ultimate goal of eliminating cancer as a major health problem for this and future generations.

A local enrollment opportunity is coming up July 19 and 20 in Fort Smith. You can find more information on enrollment on the event website. Feel free to share the site and recruit your friends and family. Together, we can make an impact on the future of cancer in our world.
