Dr. Champion talks about colorectal cancer, a leading cause of cancer death
Monday, March 9, 2020
Colorectal cancer is among the top causes of cancer death in Indiana. The number of Hoosiers who die from colorectal cancer is higher than the national average, especially among African Americans. Equally troublesome, Hoosiers lag the rest of the country when it comes to screening, which has been shown to be effective in decreasing the number of deaths from colon cancer.
We caught up with Victoria Champion, Ph.D., R.N., to learn more about the disease and efforts at the IU Simon Comprehensive Cancer Center to help turn the tide. Dr. Champion, an IU Distinguished Professor and Edward W. and Sarah Stam Cullipher Professor at IU School of Nursing, leads the Office of Community Outreach and Engagement at the cancer center. She is the cancer center’s Associate Director of Community Outreach and Population Science Research.
Q: Most Hoosiers would probably correctly say that lung and breast cancer are among the top causes of cancer deaths in Indiana. Do you think most would be surprised to know that colon cancer is among the most common death risks for Hoosiers?
Dr. Champion: Yes, for several reasons. Many people are not comfortable talking about a problem related to their colon, therefore it is easy to ignore. Secondly, colon cancer does not get the publicity that lung or breast cancer do so people don’t realize it is a significant problem.
Q: For many years, you and your colleagues have led research on the cancers that cause the most deaths in Indiana. What has been learned about colon cancer among Hoosiers?
Dr. Champion: We have learned that people don’t like to think about colon cancer because it involves a body function that people consider private or distasteful. Because people don’t like to think about this, they also don’t like to think about screening, which either prevents the cancer or finds it early enough that it can be successfully treated. Until people become more comfortable discussing colon cancer and doing something about it, I am afraid it will be a significant cause of death – especially for Hoosiers.
Q: Your office has an impact across the state, not only in trying to reduce both the incidence and mortality rates caused by this cancer but other cancers as well. But, let’s stay focused on colon cancer for the moment. What efforts and partnerships are underway to make Hoosiers aware of this deadly cancer and screening options?
Dr. Champion: The Indiana State Department of Health and the American Cancer Society received a grant from the Centers for Disease Control and Prevention to educate Hoosiers and health care providers about the necessity of colon cancer screening and about the different screening options available. We are also partnering with the Indiana Clinical Translation Science Initiative to provide a cancer liaison who works with partners around the state to increase colon cancer screening. Here at the IU Simon Comprehensive Cancer Center, our researchers are studying ways to implement colon cancer screening options into primary care practices throughout the state. We are currently partnering with the Indiana Rural Health Association to submit a large implementation grant to help rural primary-care practices increase their screening rates.
Q: Is it true that colorectal cancer is preventable?
Dr. Champion: Yes, colorectal cancer is preventable. Through colonoscopy, precancerous polyps can be removed before they turn into cancer. Additionally, there are several unhealthy behaviors that increase your risk for colon cancer such as smoking, excessive alcohol consumption, a diet high in red meats, lack of exercise, and excess weight, especially around the middle of your body. We can do a lot with a healthy lifestyle to prevent colon cancer.
Q: Do we know why the colon and rectal cancer mortality rate is higher for African Americans than for Caucasians? Are other minorities also at greater risk of dying from this type of cancer? Are residents of any particular region of Indiana more at risk for developing and dying from colorectal cancer?
Dr. Champion: We know that African Americans have lower colon cancer screening rates in Indiana and this could be a significant factor in later stage diagnosis. We also know that African Americans have a higher incidence of obesity in Indiana, which could put them at greater risk, especially if their excess weight is around the middle of their body. The mortality for colon cancer is greater in Indiana compared to the average for the nation and, in the Hoosier state, Blackford and Jay counties in east central Indiana, have higher mortality rates than the Indiana average, but there is not an obvious reason for this occurrence.
Q: What about colon cancer screening, which includes options such as at-home stool tests and colonoscopy? Why don’t Hoosiers take advantage of this life-saving screening?
Dr. Champion: There are many reasons people don’t get screenings – many more than can be discussed here. It is important for people to know that if they are at average risk, there are options. Not everyone has to have a colonoscopy. Still, everyone over the age of 50 needs to talk to their doctor about what test is right for them. At-home stool tests offer a good alternative to colonoscopy for many people, but only the individual and his or her doctor can decide what is best.
Q: Through your research, have you found any outreach efforts effective in getting Hoosiers to be screened for various cancers, particularly colorectal cancer?
Dr. Champion: One of the most effective tools is simply having a doctor recommend the test. Another is making colon cancer screening convenient, such as mailing a stool test kit to the patient’s home. Unfortunately, many times people are not screened because a health care provider doesn’t suggest it at a health care visit or the person forgets to schedule a screening and the physician’s office doesn’t have a reminder system in place.
Q: If you had a magic wand and could change one thing concerning attitudes or behaviors about health in Indiana, what would it be?
Dr. Champion: It would be that people in Indiana take active responsibility for their health and work with their health care provider to prevent or find cancer early. The majority of deaths from cancer could be prevented if people knew about and worked on healthy behaviors and prevention. Healthy behaviors that can prevent the development of cancer or detect it early include: not smoking, getting cancer screening as recommended by national guidelines, eating healthy, exercising and maintaining a healthy weight.
