About a year ago, a friend of mine who just turned fifty went for her screening colonoscopy and was found to have an early stage colon cancer requiring surgery. She was understandably upset when she heard the word CANCER but was relieved in the end that she had her colon cancer screening and did not delay which could have led to a different outcome. She, along with my patients, (I am a Gastrointestinal Oncology Nurse Practitioner) inspired me to proceed with my first colonoscopy last year.

The American Cancer Society (ACS) changed their recommendation to start colon cancer screening at age 45 in 2018 which had previously been to start at age 50. The ACS made changes because data showed there was a rising incidence of colorectal cancer being diagnosed in younger and middle-aged patients.

A sessile serrated adenoma was found when my colonoscopy was done. This type of polyp is not cancerous but can be pre-cancerous. This type of polyp has an increased risk of developing into a colon cancer if not addressed early.

With this being identified I had a repeat colonoscopy this year and no polyps were seen. My gastroenterologist suggested a repeat colonoscopy in two years.

Colon cancer screening presents concerns for many patients that are reported as: unpleasantness of the prep, financial costs, time away from work/limit time to complete the prep, lack of transportation to appointments and now COVID concerns. Colorectal cancer screening should not put off until the pandemic is over. I try to reassure my patients when they are due for their colonoscopy screening as part of their surveillance after their colon cancer treatment.

For patients who do not have a history of colon cancer there are a few options for colon cancer screening. Colonoscopy is the preferred and gold standard for testing. Other tests include: flexible sigmoidoscopy, CT colonography, FIT (fecal immunochemical test), High-sensitivity Guaiac based Fecal Occult Blood Test (HSgFOBT), Multi-target Stool DNA Test (MT-sDNA). Each of these tests have pros and cons as any testing does. You should discuss the options and what is best for you with your primary care provider.

There are few things I would recommend that you ask your primary care provider when discussing colon cancer screening:
  • If you are 45 and older ask your Primary Care Provider (PCP) if they recommend you schedule your screening colonoscopy.
  • If you are concerned about a colonoscopy, ask your PCP what are other options for colon cancer screening and what are the pros/cons of that type of testing versus a colonoscopy?
  • What do I need to do to prepare for the test?
  • What should I expect during the test and how long does it last?
  • How long does it take to get the test results?
  • What happens if an abnormality is identified?
  • What are things I can do to prevent developing colon cancer?
I strongly recommend commitment to colon cancer screening as it can decrease the deaths related to colon cancer. Screening is most effective when it is done! So get to it !

For patients who do not have insurance and have no prospects of obtaining it, the cost of FIT-DNA testing is $500–$600 versus $2,750 for colonoscopy (national average), and $24 for FIT alone. Clearly, in this instance, FIT alone is most cost effective, with an additional acceptable cost of FIT-DNA with a higher sensitivity and a slightly better polyp detection rate.

When choosing the best test for your patient, there are two practical mantras: some screening is better than no screening, and the best test is the one that will get done. While cancer detection rates may be nearly equivalent between FIT-fecal DNA and colonoscopy, colonoscopy is the clear choice for advanced polyp detection and removal before cancer is established.
