Maged Khalil, MD, medical oncologist with LVPG Hematology Oncology and Associate Director of Clinical Research with Lehigh Valley Topper Cancer Institute says the incidence of colorectal cancer has increased significantly in adults ages 40-50 and is rising among young adults 20-39. “Those under age 50 who are diagnosed with colorectal cancer often have more advanced disease. The reason for this trend is unclear, but 35 percent of these young adult cancers are associated with known hereditary colorectal cancer syndromes, like familial adenomatous polyposis (FAP) and Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC]), which are the most common of the inherited colon cancer syndromes,” Dr. Khalil says.
Family history also plays an important role, according to Dr. Khalil. “Having just one first-degree relative – parent, sibling or child – with colorectal cancer increases your risk by twofold over that of the general population,” he says.
And your personal health history is important too, especially if you have a condition like Crohn’s disease or ulcerative colitis, among others. “There is a well-documented association between inflammatory bowel disease and colon cancer, with the extent, duration and activity of disease being the primary determinants. However, there is evidence that treatment for inflammatory colitis may help decrease colorectal cancer risk,” Dr. Khalil says.
Boseman’s family has not shared if he had any of these condition-related risk factors.
Cancer-fighting power: Colonoscopy
Colonoscopy is regarded as the gold standard screening tool for detecting any cancerous changes that may occur in the colon or rectum. This procedure also allows for the removal of benign polyps (growths) that may line the colon and potentially develop into cancer.
You and your primary care clinician should discuss your risk for colorectal cancer and a screening method to help detect it. Colonoscopy is recommended for adults (45 and older) who have an average risk for colorectal cancer. If you have a colonoscopy and no polyps are detected, your next colonoscopy would occur 10 years later, provided you don’t have symptoms associated with colorectal cancer in those intervening years.
Other screenings are available, though they have limitations (compared to colonoscopy). Those screenings include:
Fecal immunochemical test (FIT)
- Frequency: Annually
- Where test is done: At home; sample sent to lab
- Looks for: Hidden blood in stool
Multi-target stool DNA (MT-sDNA) screening
- Frequency: Every three years
- Where test is done: At home; sample sent to lab
- Looks for: Biomarkers associated with colorectal cancer
- Frequency: Every five years
- Where test is done: Radiology department
- Looks for: Any growths or changes in the large bowel or rectum
“Though these other methods can be used by people who are at average risk, if any screening test comes back as positive, it should be followed up with a diagnostic colonoscopy,” Dr. Khalil says.
Pay attention: Signs of colorectal cancer
Colorectal cancer is highly treatable in early stages – it also does not cause noticeable symptoms early on. Pay attention to any of these signs of colorectal cancer and speak with your primary care clinician about them:
- Tiredness (weakness)
- Weight loss you cannot control
- Blood in your stools that make them appear a dark color
- Change in bowel habits, which may include frequent diarrhea or narrow stools
- Feeling the urge to have a bowel movement after just having one
- Cramping in your belly
Help reduce your risk
In addition to knowing your family history and having regular screenings for colorectal cancer, there are some ways you can improve the health of your colon:
- Eat a diet that includes fresh fruits, vegetables and fiber.
- Limit red meat and processed meats.
- Maintain a healthy weight.
- Exercise regularly.
- Don't smoke.
- Limit alcohol intake.
You can do it
Talk with your doctor or primary care clinician about your family history and any concerns you have about your poop habits or unexplained pain or weight loss. Also, don’t let fear of prep for a colonoscopy prevent you from getting this important screening. You can do it. And if cancer is detected, earlier stage diagnosis is always preferable to improve your odds of beating colorectal cancer.
