Office Visit: What to Know About Colorectal Cancer and how to Protect Your Health
March 27, 2025
Colorectal cancer, including cancer of the colon and rectum, is one of the most common cancers in the United States. The good news is it can be detected early and often prevented with increased awareness and proactive measures.
What is colorectal cancer?
Colorectal cancer begins in the digestive tract, specifically in the large intestine or rectum. It can develop from polyps, small growths that can become cancerous. Symptoms vary, but many people experience changes in bowel habits, persistent abdominal discomfort, rectal bleeding and unexplained weight loss.
What are the risk factors?
Primary risk factors include age, family history, personal history of inflammatory bowel disease, sedentary lifestyle and a diet high in red or processed meats.
Prevention tips:
- Get screened: Regular screening is among the most effective ways to prevent colorectal cancer. The American Cancer Society recommends people begin screening at age 45. Those with a family history or other risk factors should consult their health care provider for personalized recommendations.
- Adopt a healthy diet: A diet rich in fruits, vegetables, whole grains and lean proteins can lower colorectal cancer risk. Aim for a variety of foods high in fiber, promoting digestive health and regular bowel movements. Additionally, red and processed meats should be limited because they have been linked to higher cancer risk.

- Stay active: Regular physical activity is essential for maintaining overall health and can reduce colorectal cancer risk. Aim for at least 150 minutes of moderate exercise each week.
- Maintain a healthy weight: Obesity increases risk of several cancers, including colorectal cancer. Keeping a healthy weight through balanced eating and regular exercise can prevent cancer.
- Limit alcohol and quit smoking: Excessive alcohol consumption and tobacco use are significant risk factors for colorectal cancer. If you drink, do so in moderation and consider seeking resources to quit smoking if you use tobacco products.
- Know your family history: Discuss incidents of colorectal cancer in your family with your health care provider. This information can guide creening and preventive strategies.
Colorectal cancer is a serious health concern. You can play a role in your health by understanding the risks and implementing preventive strategies. Discuss screening options with your health care provider and encourage loved ones to do the same. Early detection saves lives.
