While many of our lives have revolved around the pandemic in recent months, the death of actor Chadwick Boseman is a tragic reminder that there is more to our health than COVID-19. Boseman, known most notably for his role in “Black Panther”, died at just 43 years old of complications related to colon cancer, shocking fans worldwide. Colorectal cancer (CRC), cancer affecting the colon or rectum, is the second-leading cause of cancer death in the United States, responsible for 51,000 deaths in 2018 alone, many of which may have been prevented by routine screenings. Despite the severity of the disease however, routine preventative screenings for colorectal cancer have decreased dramatically during COVID-19. A study by Epic Health, for instance, found that colorectal cancer screenings dropped by 86 percent immediately following the pandemic. While Boseman’s death may not have been preventable by screening, it brings a spotlight to the importance of colorectal cancer screenings, even amid the coronavirus pandemic. Having an understanding of your risk level and a relationship with your PCP can help to make sure you are taking advantage of the screening options that are recommended for you. Below is a guide on how you can identify colorectal cancer and work with your primary care provider to determine the right time to start screening.

What are the signs of colorectal cancer?

One of the reasons why colorectal cancer is so fatal is because you could have no symptoms at all, which is why regular screening is pivotal in identifying colorectal cancer and preventing things from getting worse. That being said, if symptoms do present themselves, there are some key signs to be on the lookout for.

The hallmark signs of colorectal cancer are blood in your stool (which can be bright red or black) and/or changes in the caliber of your stool. You can also experience abdominal pain and changes in bowel movements.

If you have any of these symptoms, don’t panic! There are several other less harmful conditions that could cause these exact symptoms, such as hemorrhoids, tears around your rectum after a hard bowel movement, and diverticulitis. On top of that, if you are younger than 40 and have no family history of colorectal cancer at a young age, your chances of colorectal cancer are quite low. If you are having symptoms though, it is important to not ignore them and check in with your primary care provider to see what is going on.

Who is at higher risk?

Recent headlines have been highlighting the growing body of research showing an increased number of colorectal cancer cases among younger individuals (40s and early 50s), but the majority of cases typically occur among men and women in their 60s and 70s. Older age is a major risk factor for colorectal cancer, but there are other unique risk factors that may increase your chances of developing colorectal cancer.

  • Family history
    • Anyone with an first-degree relative (parents or siblings) diagnosed with CRC
    • Anyone with a family history of CRC in a first-degree relative younger than 60 or two first-degree relatives at any age are at significantly higher risk and will need to be screened younger and more frequently.
  • Race: Case rates and deaths from CRC impact communities of color differently, but more research is needed in identifying the underlying cause of these health disparities. For example, CRC disproportionately impacts the black community, with African Americans having both higher case rates and deaths compared to white communities. The cause of this is multifactorial, but this health disparity is one that needs to be considered in improving the detection and treatment of CRC in the black community.
  • Nutrition: Diets high in red meat and processed meat have been found to be associated with higher rates of cancer.
  • Obesity: Individuals who have a BMI >30 are at higher risk of developing colorectal cancer
  • Smoking: tobacco smokers are more likely to die from colorectal cancer than non-smokers
  • Inflammatory bowel disease (IBD): Not to be confused with Irritable Bowel Syndrome (IBS), IBD can lead to chronic inflammation of the large intestine, which in turn increases the risk of colorectal cancer

When should I start screening?

At One Medical, we believe the decision to start screening for CRC should be tailored to you and your specific health needs. We encourage you to have a discussion around age 45 with your primary care provider about when to start screening for colorectal cancer, as we are here to help guide you in your health and find the path that makes sense for you.

While colorectal cancer screening is strongly recommended by the American Cancer Society and the United States Preventive Services Task Force (USPSTF) for all people between the ages of 50-74, the American Cancer Society released a recommendation in 2018 that routine screening for average risk individuals should start at 45 years old. In October of 2020, the USPSTF announced that it too is considering (still in development) lowering the recommended age of colorectal screening to age 45 as early screening has demonstrated moderate benefits with little harm. This change was because of a growing body of data showing increasing cases of colorectal cancer in younger individuals. More research is needed to better understand the pros and cons of screening for colon cancer earlier, which is why medical providers may have differing opinions on when to start. This is also why some health insurances may not cover screenings at any age earlier than 50.

The decision to screen for colorectal cancer in adults between the ages of 76 -85 should be an individual one, as the benefits of screening can be much smaller after 75 depending on an individual's current health and life expectancy. The decision to be screened should be based on a person’s overall health and prior screening history to determine whether the benefits outweigh the potential harm from invasive testing and follow up procedures.

How do I screen?

There are several options for colon cancer screening, including a colonoscopy at least once every ten years or a stool test kit (also known as a FIT ) every year that can be done from the comfort and privacy of your own home. A FIT looks for tiny amounts of blood in your stool and may require follow-up testing if found. Colonoscopies are an invasive procedure where you will need to be referred to a gastroenterologist to perform the procedure. FIT tests on the other hand can be ordered by your primary care provider and picked up at any One Medical lab on the same day.

We recommend you discuss with your primary care provider to determine the best colon cancer screening method for you based on your personal and family history.
