Colon Cancer Screening Q & A

What is colon cancer screening?

Colon cancer screening includes procedures that detect the presence of colon cancer, which affects the lower part of your digestive tract (your large intestine). About 1 in 23 men and 1 in 25 women get colorectal cancer at some point. Early detection and treatment offer your best chance of beating the disease.

What are the symptoms of colon cancer?

The common symptoms of colon cancer include:

  • Rectal bleeding
  • Blood in your stool
  • Diarrhea
  • Constipation
  • Bowel changes
  • Weakness
  • Fatigue
  • Unexplained weight loss
  • Cramps
  • Gas
  • Abdominal pain

Colon cancer can also cause a feeling that your bowel doesn’t empty completely. During the early stages of colon cancer, you might not have any symptoms.

Do I need colon cancer screening?

Your Lone Star Gastroenterology specialist lets you know if you’re a candidate for colon cancer screening if you’re at risk of developing it. They review your symptoms and medical history, check your vital signs, and complete a physical exam.

Colon cancer risk factors include:

  • Being over 50
  • Being African American
  • Family or personal history of colon cancer/polyps
  • Certain gene mutations
  • Inflammatory intestinal problems
  • Crohn’s disease
  • Ulcerative colitis
  • Being sedentary
  • Low-fiber diet
  • Diabetes
  • Obesity
  • Smoking
  • Alcohol
  • Cancer radiation therapy

Ways to reduce your chance of developing colon cancer include eating high-fiber foods and reducing your alcohol intake. Don’t smoke, exercise regularly, and maintain a healthy body weight.

A genetic study can be performed for high risk family history of colon cancer.

What kinds of colon cancer screening are there?

The common colon cancer screening procedures include:


During a colonoscopy, your doctor inserts a flexible tube into your rectum. It has a video camera attached to it, which allows your specialist to obtain an in-depth view of the inside of your colon and rectum. The procedure usually lasts 30-60 minutes.

Stool tests

Lone Star Gastroenterology also offers stool tests. Your provider takes a stool sample and looks for DNA changes that indicate colon cancer, blood in your stool, and precancerous conditions.

Virtual colonoscopy

A virtual colonoscopy, also called CT colonography, is a procedure that creates images of the inside of your abdominal organs. It allows your provider to detect colon and rectum abnormalities. Your specialist first places a tiny tube inside your rectum to fill your colon with air.
