Colorectal Cancer Explained

A Simple Guide for Houston Residents

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.”

In this guide, we'll cover:

We'll also answer some of the most common questions at the end. Let's get started.

1. What Is Colorectal Cancer?

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.

2. Early Signs and Symptoms

Knowing the warning signs can save lives. Here are the most common symptoms:

“These symptoms can also happen with less serious issues,” says Dr. Pothuri. “Still, don't ignore them-talk to your doctor in Houston.”

3. What Increases Your Risk?

Some people are more likely to get colorectal cancer. You're at higher risk if you:

“If we know your risks, we can create a screening plan that works best for you,” explains Dr. Pothuri.

4. How Does It Develop?

Here's a simple look at how colorectal cancer forms:

Removing polyps during a colonoscopy can stop cancer before it starts.

5. Screening Saves Lives

Screening finds polyps or cancer before symptoms appear. Here's a quick guide:

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.

6. Cancer Stages Explained

Knowing the stage helps doctors choose the right treatment:

Each stage helps guide your treatment and recovery plan.

7. How Is It Treated?

Treatment depends on the stage and your health. Here are the common options:

“We use a team-based approach in Houston,” says Dr. Pothuri. “Each plan is customized.”

8. Preventing Colorectal Cancer

You can lower your risk with these diet and lifestyle changes:

“Good habits can cut your risk by nearly 40%,” says Dr. Pothuri. “Houston's great weather is perfect for staying active!”

9. What's the Outlook?

Your chance of survival depends on when the cancer is found:

Early detection makes a big difference. That's why screening is so important.
