Could Lower Abdominal Pain After 50 Be Colon Cancer or an Aneurysm?

Lower abdominal pain is a common complaint in adults over 50. Most cases are due to benign conditions, but on occasion the discomfort can signal something more serious—such as colon cancer or an abdominal aortic aneurysm (AAA). Understanding the warning signs and risk factors can help you decide when to seek medical attention.

Common Causes of Lower Abdominal Pain After 50

Before diving into red-flag conditions, it’s useful to know the more frequent, less serious causes of abdominal pain after age 50:

• Diverticulitis
  Small pouches (diverticula) in the colon become inflamed or infected. Symptoms often include cramping pain (usually on the left side), fever, and changes in bowel habits.
• Irritable Bowel Syndrome (IBS)
  A functional disorder with cramping, bloating, constipation or diarrhea. It does not cause permanent damage to the colon.
• Urinary Tract Infections (UTIs)
  Can cause lower abdominal discomfort, burning with urination, and frequent urges to urinate.
• Kidney Stones
  Sharp, cramp-like pain often radiating from the back to the lower abdomen or groin, sometimes accompanied by blood in the urine.
• Hernias
  A bulge in the groin or lower abdomen that can become painful when coughing or lifting.

While these are more common, it’s always wise to rule out serious conditions—especially if you’re over 50.

When to Consider Colon Cancer

Colon cancer risk rises with age. While screening colonoscopies usually begin at 45–50, pain or other symptoms before your next scheduled test may warrant a closer look.

Key Risk Factors

• Age over 50
• Family history of colorectal cancer or polyps
• Personal history of inflammatory bowel disease
• Lifestyle factors (smoking, heavy alcohol use, low-fiber diet, obesity)

Warning Signs

• Persistent abdominal pain that doesn’t go away with basic treatments
• Changes in bowel habits, such as ongoing diarrhea, constipation or narrowing of stools
• Blood in the stool (bright red or very dark)
• Unexplained weight loss
• Fatigue or weakness, possibly due to anemia

If you notice any combination of these signs—especially rectal bleeding or significant changes in bowel function—talk to your doctor. Early detection of colon cancer dramatically improves treatment options and outcomes.

When to Consider an Abdominal Aortic Aneurysm (AAA)

An AAA occurs when the large blood vessel supplying blood to the abdomen, pelvis and legs becomes abnormally large or balloons outward. If it ruptures, the result can be life-threatening.

Key Risk Factors

• Age over 65 (men more often than women)
• History of smoking (current or former)
• High blood pressure
• Family history of aneurysms
• Atherosclerosis (hardening of the arteries)

Warning Signs

• Sudden, severe pain in the lower abdomen or back, often described as tearing or ripping
• Pulsating feeling near the navel
• Low blood pressure, dizziness or fainting (if the aneurysm starts to leak or ruptures)
• Rapid heart rate

An AAA may be present without symptoms until it’s large or leaking. That’s why one-time screening with an abdominal ultrasound is recommended for men 65–75 who have ever smoked. If you experience sudden, intense abdominal or back pain—especially with lightheadedness—call emergency services right away.

Red Flags: When to Seek Immediate Care

Any of these signs accompanying lower abdominal pain warrant prompt medical evaluation:

• Severe, sudden pain that intensifies rapidly
• Pain with fever over 100.4°F (38°C)
• Repeated vomiting or inability to keep fluids down
• Bloody or tarry stools
• Lightheadedness, fainting or sudden drop in blood pressure
• Pain that wakes you from sleep

Call 911 or go to your nearest emergency department if you suspect an aneurysm rupture or other life-threatening event.

How Your Doctor Will Evaluate Lower Abdominal Pain

When you see your healthcare provider, expect:

1. Detailed medical history
   Discuss onset, location, intensity and character of the pain, plus any changes in bowel or urinary habits.
2. Physical examination
   Palpation of the abdomen to locate tenderness, assess for a pulsating mass, or detect signs of inflammation.
3. Laboratory tests
   Blood tests for anemia, infection markers; stool tests for blood or infection.
4. Imaging studies
   • Abdominal ultrasound (to screen for aneurysm)
   • CT scan or MRI (to evaluate colon pathology or diverticulitis)
5. Endoscopic evaluation
   Colonoscopy may be recommended for direct visualization of the colon if cancer or polyps are suspected.

What You Can Do Now

• Monitor your symptoms. Note changes in pain intensity, bowel habits, fevers or bleeding.
• Adopt healthy lifestyle habits:
  • High-fiber diet (fruits, vegetables, whole grains)
  • Regular exercise
  • Smoking cessation
  • Moderate alcohol intake
• Stay up to date on recommended screenings, such as colonoscopy.
• Consider a free, online symptom check, using the doctor approved Ubie Symptom Checker to help you better understand your symptoms and gauge urgency.
