Colorectal cancer is one of the most common cancers worldwide and a leading cause of cancer-related deaths. Yet it is also among the most preventable and treatable cancers when detected early.
The key to improving survival rates lies in timely colorectal cancer screening, which can detect abnormal growths or early-stage cancer before symptoms become severe.
Despite this, many individuals delay screening due to lack of awareness or fear of the procedure. Understanding the early signs of colorectal cancer, the importance of routine screening, and the available treatment options can empower individuals to take proactive steps toward protecting their health.
At Chinese General Hospital and Medical Center (CGHMC), patients have access to comprehensive cancer screening programs and advanced treatment options, including minimally invasive and robotic-assisted colorectal surgery.
Understanding Colorectal Cancer
Colorectal cancer develops in the colon or rectum, which are parts of the large intestine responsible for absorbing water and storing waste before elimination.
Most colorectal cancers begin as polyps, which are small, abnormal growths on the inner lining of the colon or rectum. While not all polyps become cancerous, some can gradually develop into cancer over time.
This process can take several years, which is why routine colorectal cancer screening plays a critical role in prevention. Screening allows doctors to detect and remove polyps before they become malignant.
Early Signs of Colorectal Cancer
In its early stages, colorectal cancer may not cause noticeable symptoms. However, as the disease progresses, individuals may begin to experience certain warning signs.
Some of the early signs of colorectal cancer include:
- Persistent changes in bowel habits (diarrhea or constipation)
- Blood in the stool or rectal bleeding
- Abdominal discomfort, cramps, or bloating
- Unexplained weight loss
- Fatigue or weakness
- A feeling that the bowel does not empty completely
These symptoms may also be associated with other digestive conditions, but persistent or worsening symptoms should always be evaluated by a healthcare professional.
Early medical consultation allows doctors to determine whether further testing or colorectal cancer screening is needed.
Who Is at Risk?
While colorectal cancer can affect anyone, certain factors may increase the likelihood of developing the disease.
Common risk factors include:
Age
The risk increases significantly after the age of 45, which is why screening is often recommended beginning at this age.
Family History
Individuals with a family history of colorectal cancer or colon polyps may have a higher risk and may require earlier or more frequent screening.
Lifestyle Factors
Certain lifestyle habits can contribute to colorectal cancer risk, including:
- Diets high in processed or red meat
- Low fiber intake
- Sedentary lifestyle
- Smoking
- Excessive alcohol consumption
Inflammatory Bowel Disease
Conditions such as ulcerative colitis or Crohn’s disease may increase the risk of developing colorectal cancer.
Understanding these risk factors can help individuals make informed decisions about preventive screening.
Why Colorectal Cancer Screening Matters
Screening is one of the most effective ways to reduce the impact of colorectal cancer.
Routine colorectal cancer screening helps doctors detect:
- Precancerous polyps
- Early-stage cancer before symptoms develop
- Other abnormalities in the colon
When colorectal cancer is detected at an early stage, treatment outcomes are significantly better. Early-stage colorectal cancer often has a high survival rate, especially when treated promptly.
For many patients, screening not only detects cancer early—it can actually prevent cancer by removing polyps before they become malignant.
Recommended Screening Guidelines
Medical organizations recommend that individuals at average risk begin colorectal cancer screening at age 45.
However, people with higher risk factors may need to start screening earlier.
Common screening methods include:
Colonoscopy
A colonoscopy allows doctors to examine the entire colon using a flexible camera. If polyps are found, they can often be removed during the same procedure.
This test is considered the gold standard for colorectal cancer screening.
Stool-Based Tests
Certain non-invasive tests analyze stool samples to detect hidden blood or abnormal DNA associated with colorectal cancer.
These tests may be recommended for individuals who are unable to undergo colonoscopy. Imaging Tests
In some cases, specialized imaging tests may be used to evaluate the colon for abnormalities.
Doctors will recommend the most appropriate screening method based on the patient’s age, risk factors, and medical history.
Treatment Options for Colorectal Cancer
If colorectal cancer is diagnosed, treatment depends on the stage of the disease and the patient’s overall health.
Treatment options may include:
- Surgery to remove the tumor
- Chemotherapy
- Radiation therapy
- Targeted therapy
- Immunotherapy in selected cases
One of the most significant advances in surgical treatment is the development of robotic colorectal surgery, which offers a more precise and minimally invasive approach.
Robotic Colorectal Surgery: A Modern Surgical Approach
Robotic-assisted surgery represents an important advancement in colorectal cancer treatment in the Philippines.
Using robotic technology, surgeons can perform highly precise procedures through small incisions while maintaining greater control and visualization.
Benefits of robotic colorectal surgery may include:
- Smaller incisions
- Reduced blood loss
- Lower risk of complications
- Shorter hospital stay
- Faster recovery
At CGHMC, robotic-assisted procedures are part of the hospital’s commitment to delivering advanced and patient-centered cancer care.
Comprehensive Cancer Care at CGHMC
Cancer care involves more than just treatment—it requires a coordinated approach that supports patients through every stage of their journey.
CGHMC provides a comprehensive cancer care continuum, which includes:
- Early detection and screening programs
- Advanced diagnostic imaging
- Multidisciplinary cancer treatment planning
- Minimally invasive and robotic surgical procedures
- Post-treatment monitoring and survivorship care
This integrated approach ensures that patients receive personalized care tailored to their specific needs.
When Should You See a Doctor?
Individuals should consider consulting a doctor if they experience:
- Persistent changes in bowel habits
- Blood in the stool
- Unexplained abdominal pain
- Unintentional weight loss
- Ongoing fatigue
Even in the absence of symptoms, adults aged 45 and older should discuss colorectal cancer screening with their healthcare provider.
Preventive screening can detect potential problems before they develop into serious disease.
The Power of Early Detection
Colorectal cancer is one of the few cancers where screening can prevent the disease altogether. By detecting and removing precancerous polyps early, doctors can stop cancer before it develops.
Raising awareness about the early signs of colorectal cancer and encouraging routine screening are essential steps toward reducing the impact of this disease.
At Chinese General Hospital and Medical Center, patients have access to advanced screening technologies, expert specialists, and comprehensive cancer care.
Taking the step to schedule a screening today may help protect your health and ensure peace of mind for the future.
