What Is Colorectal Cancer?
Colorectal cancer originates in the colon or rectum, both of which are part of the digestive system. It typically begins as small, benign clumps of cells called polyps that can develop into cancer over time. While not all polyps turn cancerous, regular screenings can help identify and remove them before they become a threat.
Risk Factors for Colorectal Cancer
Several factors can increase the likelihood of developing colorectal cancer, including:
Age: Most cases occur in individuals over 50, although younger people can also be affected.
Family History: A family history of colorectal cancer or polyps can increase risk.
Diet: Diets high in processed meats and low in fiber have been linked to higher risks.
Lifestyle Factors: Smoking, excessive alcohol consumption, lack of exercise, and obesity contribute to increased susceptibility.
Chronic Conditions: Inflammatory bowel diseases like Crohn’s disease and ulcerative colitis can raise the risk.
Symptoms to watch for:
Colorectal cancer often presents no symptoms in its early stages, making regular screenings crucial. However, as the disease progresses, common symptoms include:
Changes in bowel habits, such as persistent diarrhea or constipation
Blood in the stool or rectal bleeding
Abdominal pain, cramps, or bloating
Unexplained weight loss
Fatigue or weakness
The Importance of Early Detection
Colorectal cancer is highly treatable when detected early. Screening tests such as colonoscopies, stool tests, and sigmoidoscopies can identify abnormal growths before they become cancerous. The American Cancer Society recommends that individuals at average risk begin screening at age 45, though those with higher risk factors may need earlier or more frequent screenings.
Prevention Strategies
While some risk factors are beyond control, adopting a healthy lifestyle can significantly lower the risk of colorectal cancer. Here are some key preventive measures:
Eat a Balanced Diet: Incorporate plenty of fruits, vegetables, whole grains, and lean proteins into your meals.
Stay Active: Regular physical activity helps maintain a healthy weight and reduces cancer risk.
Limit Alcohol and Quit Smoking: Both habits are linked to an increased risk of colorectal and other cancers.
Get Screened: Early detection through routine screenings is one of the most effective ways to prevent colorectal cancer.
March is recognized as Colorectal Cancer Awareness Month, making it an excellent time to discuss the importance of screenings and lifestyle modifications. By educating ourselves and others, we can help reduce the number of colorectal cancer cases and improve survival rates.
If you or a loved one is due for a screening, take action today. Awareness and early detection are key to fighting colorectal cancer and living a healthier life.
