Hemorrhoids vs Colorectal Cancer: Know the Difference

Rectal bleeding is often caused by hemorrhoids, but it can also be a sign of colorectal cancer. Here's how to tell the difference and when to get checked.

Why This Matters

• Hemorrhoids affect 50%+ of adults
• Colorectal cancer is the 3rd most common cancer
• Both can cause rectal bleeding
• Early detection of cancer saves lives

Key Differences

When to Get Checked

See a doctor immediately if you have:

• Bleeding with any concerning features
• Unexplained weight loss
• Persistent changes in bowel habits
• Family history of colorectal cancer
• Age 45+ with new bleeding

The age 45 rule: Colorectal cancer screening (colonoscopy) is now recommended starting at age 45 for average-risk individuals.

Risk Factors for Colorectal Cancer

Non-modifiable:

• Age (risk increases after 45)
• Family history of colorectal cancer or polyps
• Personal history of polyps
• Inflammatory bowel disease
• Certain genetic syndromes

Modifiable:

• Obesity
• Physical inactivity
• Diet high in red/processed meats
• Smoking
• Heavy alcohol use

Don't Self-Diagnose

The most important message: Don't assume bleeding is just hemorrhoids.

Many people delay evaluation because they assume their symptoms are hemorrhoids. This can lead to late-stage cancer diagnosis.

The Colonoscopy: Not as Bad as You Think

If you need a colonoscopy:

• Prep is the hardest part
• Procedure itself is under sedation
• Takes about 30 minutes
• Can remove polyps during exam
• Could save your life

What Happens at Your Appointment

Your doctor will: 1. Ask about your symptoms and history 2. Perform a physical exam 3. May do a digital rectal exam 4. May order blood tests 5. Recommend colonoscopy if indicated

Key Takeaways

1. Don't assume bleeding is hemorrhoids 2. Get screened starting at age 45 3. Know your risk factors 4. Watch for warning signs 5. See a doctor if symptoms don't match typical hemorrhoids

The Bottom Line

Hemorrhoids are common and usually not serious. Colorectal cancer is treatable when caught early.

The only way to know for sure is to get checked. Don't let embarrassment or fear of the colonoscopy put your health at risk.
