Colon cancer is one of the most common cancers in the U.S. Anyone can get it, but some factors can increase your risk. At Gastrodoxs, we believe that knowing the risks helps you take control.
This guide explains who's most at risk for colon cancer in simple terms. You'll learn how age, family history, diet, polyps, and certain diseases affect your chances. We'll also cover the role of genetics, lifestyle, screening tips, and where to get care in Houston. Let's jump in!
Dr. Bharat Pothuri says: “Family history is one of the strongest predictors. If your close relatives had colon cancer, you may need earlier and more frequent screenings.â€Â
Polyps are small growths inside the colon. Most are harmless, but some typesâ€â€like adenomatous polypsâ€â€can turn into cancer.
Dr. Pothuri says: “Catching polyps early helps prevent cancer. Your colonoscopy report tells a storyâ€â€make sure to understand it.â€Â
What you eat daily affects your colon over time. Some foods raise your risk; others protect it.
Tip: Swap hot dogs for grilled fish. Add fresh salad to meals.
IBD includes ulcerative colitis and Crohn's diseaseâ€â€both cause long-term inflammation in the digestive tract.
Dr. Pothuri says: “Managing inflammation and getting regular colonoscopies are key. We work closely with GI experts across Houston to care for our IBD patients.â€Â
Genetic counseling reviews your family's health history. You may be referred for genetic testing.
Dr. Pothuri says: “Genetic counseling helps people make smart choices. It tells us when to screen and what steps to take next.â€Â
Dr. Pothuri says: “Screening saves lives. Houston has great endoscopy centers. Don't delay care.â€Â
Dr. Pothuri says: “In Houston, you'll find expert care and community support at every stage.â€Â
