The Power of Early Screening: Treatment Starts with Screening

Colon cancer is one of the most common cancers worldwide, yet it is also one of the most preventable and treatable when detected early. The key to successful colon cancer treatment? Regular colon cancer screening. At Gastroenterology Consultants of San Antonio, we emphasize the power of early screening because treatment starts with early detection.

Understanding Colon Cancer and Its Risks

Colon cancer, also known as colorectal cancer, begins in the large intestine (colon) or rectum. It often starts as small, benign growths called polyps, which can develop into cancer over time. Many people with early-stage colon cancer experience no symptoms, making regular screening crucial for early detection.

Several risk factors can increase the likelihood of developing colon cancer, including:

• Age: While colon cancer can affect people of any age, it is most commonly diagnosed in individuals over 45.
• Family History: A family history of colorectal cancer or polyps increases the risk.
• Lifestyle Choices: Diets high in red and processed meats, a sedentary lifestyle, obesity, smoking, and heavy alcohol consumption all contribute to a higher risk.
• Medical Conditions: Individuals with inflammatory bowel diseases like Crohn’s disease or ulcerative colitis have a higher risk of developing colon cancer.

Understanding these risk factors helps highlight the importance of early and routine screening.

The Importance of Early Detection

Early detection through Colonoscopies saves lives. When colon cancer is caught in its early stages, it is far more treatable, with survival rates exceeding 90%. However, as colon cancer progresses and spreads to other parts of the body, treatment becomes more challenging, and survival rates decrease.

Screening colonoscopies allows doctors to detect and remove precancerous polyps before they become cancerous. This proactive approach prevents the development of colon cancer altogether. In cases where cancer is already present, early detection means colon cancer treatment can begin immediately, significantly improving outcomes.

Types of Colon Cancer Screening Tests:

There are several types of colon cancer screening tests, each with its benefits. The most commonly recommended screenings include:

Screening Colonoscopy

A colonoscopy is the gold standard for colon cancer screening. This procedure allows a doctor to examine the entire colon and rectum using a flexible tube with a camera. If polyps or abnormal growths are found, they can often be removed during the procedure, preventing cancer from developing. Every 10 years, if no polyps your doctor will suggest the best interval for follow-up procedures.

Fecal Immunochemical Test (FIT) & Fecal Occult Blood Test (FOBT)

These at-home stool tests detect hidden blood in the stool, which may indicate the presence of polyps or cancer. While they are non-invasive and convenient, a positive result requires a follow-up colonoscopy. We recommend these to be scheduled annually. 

CT Colonography: Virtual Colonoscopy

This imaging test uses a CT scan to create a detailed view of the colon and rectum. It is less invasive than a traditional colonoscopy but still requires bowel preparation. If abnormalities are found, a follow-up colonoscopy is needed. We recommend these to be scheduled every 5 years.

Stool DNA Test: Cologuard®

This test detects DNA changes and blood in the stool that may indicate colon cancer. Like the FIT and FOBT, a positive result necessitates a follow-up colonoscopy. We recommend these be done every 3 year years.

Shield Test

This test is a non-invasive blood test designed to detect colorectal cancer. The Shield test analyzes cell-free DNA (cfDNA) in the blood for specific alterations associated with colorectal cancer. These alterations can indicate the presence of tumors or precancerous polyps in the colon.

Who Should Get Screened?

The American Cancer Society recommends that individuals at average risk begin regular colon cancer screening at age 45. However, those with a family history of colorectal cancer, inflammatory bowel disease, or other risk factors may need to start screening earlier and undergo testing more frequently.

It is important to discuss your personal risk factors with a healthcare provider to determine the most appropriate screening schedule for you.

Overcoming Barriers to Screening

Despite the proven benefits of colon cancer screening, many individuals delay or avoid screening due to fear, misconceptions, or lack of awareness. Common concerns include:

• Fear of Discomfort: While a colonoscopy requires preparation, sedation ensures that most patients experience minimal discomfort during the procedure.
• Misconceptions About Risk: Even if you feel healthy and have no symptoms, colon cancer can develop silently. Screening is essential regardless of how you feel.
• Time Constraints: Many screening options, such as at-home stool tests, provide a convenient alternative for those with busy schedules.

Addressing these concerns with a healthcare provider can help ease anxiety and ensure individuals receive the life-saving screenings they need.

The Role of Lifestyle in Colon Cancer Prevention

In addition to regular screening, making healthy lifestyle choices can significantly reduce the risk of colon cancer. Steps you can take include:

• Eating a diet rich in fiber, fruits, and vegetables.
• Limiting red and processed meat consumption.
• Staying physically active and maintaining a healthy weight.
• Avoiding smoking and excessive alcohol intake.

By combining healthy habits with regular screenings, you can take proactive steps toward preventing colon cancer.
