Understanding Colorectal Cancer
What is Colorectal Cancer?
Colorectal cancer is cancer that starts in the colon or rectum. These organs are located in the lower part of your digestive system. The colon, also known as the large intestine, absorbs water and nutrients from digested food. The rectum is the final section of the large intestine and stores stool before it is eliminated from the body.
Most colorectal cancers start as small, noncancerous (benign) clumps of cells called polyps that form on the inside of the colon or rectum. Over time, some of these polyps can become cancerous. Screening tests can help find polyps so they can be removed before they turn into cancer . Screening can also find colorectal cancer early, when treatment is most effective.
Risk Factors for Colorectal Cancer
Several factors can increase your risk of developing colorectal cancer. Some of these risk factors are within your control, while others are not.
Age: The risk of colorectal cancer increases with age. Most cases occur in people over the age of 50. Family History: If you have a family history of colorectal cancer or adenomatous polyps, your risk is higher. Personal History: A personal history of colorectal cancer or adenomatous polyps also increases your risk. Inflammatory Bowel Disease (IBD): Chronic inflammatory diseases of the colon, such as ulcerative colitis and Crohn's disease, can increase your risk. Lifestyle Factors: Certain lifestyle factors, such as a diet low in fiber and high in fat, lack of physical activity, obesity, smoking, and excessive alcohol consumption, can contribute to an increased risk. Race and Ethnicity: African Americans have a higher risk of developing and dying from colorectal cancer compared to other racial groups.
Symptoms of Colorectal Cancer
In the early stages, colorectal cancer may not cause any symptoms. As the cancer progresses, you may experience the following symptoms:
A persistent change in your bowel habits, including diarrhea or constipation Rectal bleeding or blood in your stool Persistent abdominal discomfort, such as cramps, gas, or pain A feeling that your bowel doesn't empty completely Weakness or fatigue Unexplained weight loss
It's important to note that these symptoms can also be caused by other conditions. However, if you experience any of these symptoms, it's essential to see your doctor for an evaluation.
Colorectal Cancer Screening Methods
Colonoscopy
A colonoscopy is considered the gold standard for colorectal cancer screening. During a colonoscopy, a long, flexible tube with a camera attached is inserted into your rectum and guided through your colon. This allows your doctor to view the entire colon and rectum and identify any polyps or abnormalities.
If polyps are found during the colonoscopy, they can be removed and sent to a lab for testing. Colonoscopies are typically recommended every 10 years for individuals at average risk of colorectal cancer.
Preparation: Before a colonoscopy, you will need to follow a special diet and take a bowel preparation to clean out your colon. Procedure: The procedure is usually performed under sedation, so you will be comfortable and relaxed. Recovery: After the colonoscopy, you may experience some bloating or gas. It's important to follow your doctor's instructions for post-procedure care.
Stool Tests
Stool tests are non-invasive screening methods that can detect blood or DNA markers associated with colorectal cancer in your stool. There are several types of stool tests available:
Fecal Occult Blood Test (FOBT): This test checks for hidden blood in the stool. It needs to be done annually. Fecal Immunochemical Test (FIT): This test also checks for hidden blood in the stool and is more sensitive than FOBT. It's typically done annually. Stool DNA Test (sDNA): This test detects both blood and DNA markers associated with colorectal cancer in the stool. It's typically done every three years.
If a stool test comes back positive, you will need to have a colonoscopy to further evaluate your colon.
Flexible Sigmoidoscopy
A flexible sigmoidoscopy is similar to a colonoscopy, but it only examines the lower part of the colon (the sigmoid colon and rectum). A flexible tube with a camera is inserted into your rectum, but it doesn't go as far into the colon as a colonoscopy.
Flexible sigmoidoscopies are typically recommended every 5 years, often in combination with a FIT test done annually.
Preparation: The preparation for a flexible sigmoidoscopy is less extensive than for a colonoscopy. Procedure: The procedure is usually performed without sedation. Recovery: After the flexible sigmoidoscopy, you may experience some bloating or gas.
CT Colonography (Virtual Colonoscopy)
CT colonography, also known as a virtual colonoscopy, uses X-rays and computers to create detailed images of your colon and rectum. It's a non-invasive screening method that doesn't require a scope to be inserted into your colon.
If any abnormalities are detected during a CT colonography, you will need to have a colonoscopy to further evaluate your colon. CT colonography is typically recommended every 5 years.
Preparation: Before a CT colonography, you will need to follow a special diet and take a bowel preparation to clean out your colon. Procedure: The procedure is performed in a radiology department. Recovery: After the CT colonography, you may experience some bloating or gas.
When to Start Colorectal Cancer Screening
Recommended Screening Age
The American Cancer Society recommends that most people at average risk of colorectal cancer start screening at age 45. Previously, the recommendation was to start at age 50, but the guidelines were updated due to an increase in colorectal cancer cases among younger adults.
It's important to talk to your doctor about when to start screening and which screening method is right for you.
Screening for High-Risk Individuals
If you have a higher risk of colorectal cancer due to family history, personal history, or other risk factors, your doctor may recommend starting screening earlier or being screened more frequently.
Family History: If you have a first-degree relative (parent, sibling, or child) who has had colorectal cancer or adenomatous polyps, you may need to start screening 10 years earlier than the age at which your relative was diagnosed, but not before age 40. Personal History: If you have a personal history of colorectal cancer or adenomatous polyps, your doctor will recommend a follow-up screening schedule based on the size, number, and type of polyps that were removed. Inflammatory Bowel Disease (IBD): If you have IBD, your doctor may recommend starting screening with colonoscopy earlier and more frequently. Genetic Syndromes: Certain genetic syndromes, such as familial adenomatous polyposis (FAP) and Lynch syndrome, significantly increase your risk of colorectal cancer. If you have one of these syndromes, your doctor will recommend a specialized screening schedule.
Talking to Your Doctor
It's essential to talk to your doctor about your individual risk factors and to develop a screening plan that's right for you. Your doctor can help you weigh the pros and cons of each screening method and choose the test that's most appropriate for your situation.
Don't hesitate to ask your doctor any questions you have about colorectal cancer screening. They are there to help you make informed decisions about your health.
Overcoming Barriers to Screening
Addressing Fear and Anxiety
Many people are hesitant to get screened for colorectal cancer because they are afraid of the procedure or worried about the results. It's normal to feel anxious, but it's important to remember that early detection can save your life.
Talk to your doctor about your concerns. They can explain the procedure in detail and help you understand the risks and benefits. You can also ask about sedation options to make the procedure more comfortable.
Cost and Access to Care
Cost can be a significant barrier to colorectal cancer screening, especially for people who are uninsured or underinsured. Fortunately, many insurance plans cover colorectal cancer screening as a preventive service.
If you don't have insurance or can't afford the cost of screening, there are resources available to help. You can contact your local health department or the American Cancer Society for information about low-cost or free screening programs.
Lack of Awareness
Lack of awareness about the importance of colorectal cancer screening is another common barrier. Many people simply don't realize that screening is recommended or that it can save lives.
Help spread the word about the importance of colorectal cancer screening. Talk to your friends and family members about getting screened. Share information on social media. The more people who are aware of the benefits of screening, the more lives can be saved.
