Colorectal cancer is one of the most common cancers in the U.S., affecting both the colon and rectum. At Gastrodoxs Endoscopy Center in Houston, TX, we’re here to help you stay informed and prepared. Dr. Bharat Pothuri shares tips on how to catch it early, prevent it, and explore treatment options.
“Colorectal cancer is highly preventable and treatable when found early,” says Dr. Bharat Pothuri. “Our mission at Houston Gastroenterology is to support you every step of the way-from screening through recovery.”
We’ll also answer some of the most common questions at the end. Let’s get started.
Colorectal cancer starts in the inner lining of the colon or rectum. Cells in this lining may grow out of control and form tumors. Some stay put, but others can spread to nearby organs or lymph nodes. Since the disease often grows slowly, regular screening can catch it early-before it becomes a serious threat.
“These symptoms can also happen with less serious issues,” says Dr. Pothuri. “Still, don’t ignore them-talk to your doctor in Houston.”
“If we know your risks, we can create a screening plan that works best for you,” explains Dr. Pothuri.
Removing polyps during a colonoscopy can stop cancer before it starts.
| Test | How It Works | How Often | Pros | Cons |
| Colonoscopy | Camera checks the full colon, removes polyps | Every 10 years | Most thorough, removes polyps | Requires prep & sedation |
| FIT (Fecal Immunochemical Test) | Tests stool for hidden blood | Every year | Easy, home test | Not as detailed |
| Stool DNA Test (e.g., Cologuard) | Looks for DNA and blood in stool | Every 3 years | High accuracy | Expensive, may need follow-up |
| CT Colonography | 3D scan of the colon | Every 5 years | Non-invasive | Still needs prep, uses radiation |
| Flexible Sigmoidoscopy | Checks lower colon only | Every 5 years | Less prep, no sedation | Doesn’t check whole colon |
“Discuss the best test for you with your Houston doctor,” says Dr. Pothuri.
Each stage helps guide your treatment and recovery plan.
“We use a team-based approach in Houston,” says Dr. Pothuri. “Each plan is customized.”
“Good habits can cut your risk by nearly 40%,” says Dr. Pothuri. “Houston’s great weather is perfect for staying active!”
Early detection makes a big difference. That’s why screening is so important.
