What is Colorectal Cancer and How Does It Affect Your Diet?

Colorectal cancer is the fourth most common cancer in the United States, affecting men and women nearly equally. It can begin in the colon or rectum—parts of the lower digestive tract—and often starts as noncancerous polyps that gradually become cancerous over time.

While symptoms may not appear early, rectal bleeding, blood in the stool, abdominal pain, changes in bowel habits, anemia, and unexplained weight loss can be signs of advanced colorectal cancer. Diet and lifestyle play a major role in prevention and overall colon health.

What Is Colorectal Cancer?

Colorectal cancer refers to cancer that begins in the colon (large intestine) or the rectum. It’s sometimes called colon cancer, bowel cancer, or rectal cancer depending on where it starts. Most cases begin as small growths called polyps, which may become cancerous if not removed early.

As the cancer progresses, it can grow into deeper layers of the colon and even spread to other organs if untreated.

Risk Factors for Colorectal Cancer

Several factors can increase your risk, including:

• Family history or personal history of colorectal cancer
• Diet high in red or processed meats
• Low intake of fruits, vegetables, and calcium
• Obesity and physical inactivity
• Type 2 diabetes
• Chronic inflammatory bowel disease
• Heavy alcohol use and smoking
• Low fiber intake or long-term NSAID use

Best Foods for Colon Health

Certain foods are known to support digestive health and may help lower your risk of colorectal cancer. Here's what to include more of in your daily diet:

1. Fatty Fish

Rich in omega-3 fatty acids, fish like salmon, tuna, and sardines may reduce inflammation and support healthy cells in the colon.

2. Fruits

High in fiber and antioxidants. Great options include apples, berries, oranges, bananas, pears, and blueberries.

3. Non-Starchy Vegetables

Load your plate with leafy greens, broccoli, carrots, cabbage, cucumbers, cauliflower, and spinach. These are low in starch and high in vitamins.

4. White Meat & Eggs

Lean proteins like skinless chicken, turkey, and eggs are better alternatives to red meat and help support tissue repair and digestion.

5. Whole Grains

Whole grains like brown rice, oats, quinoa, and barley are rich in fiber and help keep your digestive tract moving.

6. Nuts & Seeds

Tree nuts like almonds, pistachios, cashews, and pecans support blood sugar balance and provide colon-protective nutrients.

7. Beans & Legumes

Black beans, lentils, peas, and soybeans offer fiber, protein, and anti-inflammatory benefits that support colon health.

Can Diet Alone Prevent Colorectal Cancer?

While diet is a critical part of prevention, it’s not a guarantee. A healthy eating pattern can lower your risk, but it’s still essential to schedule regular screenings—especially if you're over age 45 or have a family history of the disease.

When to Get Screened for Colorectal Cancer

Because symptoms often appear late, routine screening is the best way to detect colorectal cancer early. Ask your doctor about options such as:

• Colonoscopy
• Stool-based tests
• CT colonography

The right choice depends on your risk level and health history.
