All You Need to Know About Colorectal Cancer Testing

All You Need to Know About Colorectal Cancer Testing

Colorectal cancer is one of Singapore’s most common and preventable cancers, yet many individuals delay or avoid testing due to fear or lack of awareness. Testing is not just about identifying cancer—it’s about taking control of your health, catching warning signs early, and preventing the disease altogether. 

Early detection through a colorectal cancer test can significantly improve treatment outcomes.

This guide dives into everything you need to know about colorectal cancer testing in Singapore, from testing methods to symptoms you should watch out for.

Colorectal Cancer Testing: The First Step in Detection

Colorectal Cancer Testing Methods

Several methods are available for colorectal cancer testing, each with its own benefits:

  • Fecal Occult Blood Test (FOBT): Detects hidden blood in stool, an early indicator of colorectal cancer.
  • Fecal Immunochemical Test (FIT): A more sensitive alternative to FOBT, requiring no dietary restrictions.
  • Colonoscopy: Considered the gold standard for colorectal cancer screening, it allows direct visualisation and removal of polyps.
  • CT Colonography: Also known as a virtual colonoscopy, this imaging test offers a non-invasive alternative to traditional colonoscopy.
  • Sigmoidoscopy: Examines only the rectum and lower colon for abnormalities.

Benefits of Early Detection Through Testing

Early detection can help with your long-term well-being:

  • Better treatment outcomes: Detecting cancer in its early stages increases the likelihood of successful treatment.
  • Less invasive treatments: Early-stage cancers can often be treated with less aggressive therapies.
  • Reduced healthcare costs: Early diagnosis minimises the need for extensive treatments, lowering medical expenses.
  • Improved quality of life: Addressing the disease early can help individuals maintain their lifestyle and overall well-being.

Patients might undergo a colorectal cancer test if they exhibit certain risk factors or symptoms associated with the disease. 

Improving Colorectal Cancer Testing Techniques in Singapore

Singapore is at the forefront of adopting innovative approaches to enhance colorectal cancer testing, aiming to increase detection rates and save lives. Here are some developments.

Developments in Diagnostic Technology

  • Artificial Intelligence (AI): AI-powered tools assist in analysing colonoscopy results, improving accuracy and reducing missed polyps.
  • Next-Generation Sequencing (NGS): This technology enables the identification of genetic mutations linked to colorectal cancer.
  • Non-invasive biomarkers: Blood-based and stool-based biomarker tests are being developed for easier and more accurate screening.

Overcoming Challenges in Adopting New Methods

While advancements are promising, some challenges remain:

  • Cost barriers: New technologies may be expensive, limiting accessibility.
  • Public awareness: Educating individuals about new testing options is crucial to encourage participation.
  • Integration into healthcare systems: Incorporating innovative methods requires training and infrastructure upgrades.

Singapore’s healthcare system is addressing these challenges through progressive education on and implementation of new diagnostic techniques.

Colorectal Cancer Testing Policies in Singapore

Understanding government policies on colorectal cancer testing is essential for knowing what resources are available and how they affect you.

Government Regulations and Guidelines

Singapore’s Ministry of Health (MOH) has implemented screening guidelines to encourage early detection:

  • Regular screening: Recommended for individuals aged 50 and above, or earlier for those with a family history of colorectal cancer.
  • Subsidised screenings: The government provides financial support for recommended tests such as FIT and colonoscopy.
  • Public awareness campaigns: Efforts to educate the population about the importance of regular screenings.

Recognising Early Signs of Colon Cancer

Understanding and recognising the early symptoms of colon cancer is crucial for timely medical intervention in Singapore.

Common Symptoms

  • Changes in bowel habits: Persistent diarrhoea, constipation, or changes in stool consistency.
  • Rectal bleeding: Blood in stool or on toilet paper.
  • Unexplained weight loss: A sudden drop in weight without dietary or activity changes.
  • Abdominal discomfort: Persistent cramps, gas, or pain.

How Symptoms Are Addressed

When symptoms suggest potential colorectal cancer, immediate medical attention is necessary to confirm the diagnosis and begin treatment.

Recognizing early symptoms of colon cancer in Singapore, such as unexplained weight loss and persistent changes in bowel habits, is crucial for residents. 

Medical Management of Colon Cancer Symptoms in Singapore

Once symptoms are identified, doctors may recommend:

  • Diagnostic tests: Including colonoscopy, FIT, or imaging studies.
  • Initial treatments: Addressing symptoms such as pain or bleeding while awaiting test results.
  • Specialist referrals: Patients with suspicious findings are referred to colorectal surgeons or oncologists.

After a positive result from an initial colorectal cancer test, further diagnostic procedures are typically recommended to assess the extent of cancer.

Treatment Options for Colorectal Cancer

Colorectal cancer treatment varies depending on the stage and severity of the disease. Common options include:

  • Surgery: To remove cancerous tissue or polyps.
  • Chemotherapy: Often used for advanced cases to shrink tumours and eliminate cancer cells.
  • Radiation therapy: Helps target localised cancer cells.
  • Targeted therapies: Focus on specific genetic mutations in cancer cells.

The approach to colorectal cancer treatment in Singapore typically involves a combination of surgery, chemotherapy, and radiation therapy. The availability of colorectal cancer treatment options in Singapore varies depending on the stage and spread of the disease at diagnosis.

Undergoing a medical procedure for the first time can be a nerve-wracking experience, especially when you don’t know what to expect. Many patients in Singapore feel anxious about endoscopy, a standard procedure used to examine the body’s internal structures.

Understanding what endoscopy entails, from preparation to post-procedure care, can help alleviate these concerns and ensure you feel more confident and prepared.

What Is An Endoscopy Specialist?

Endoscopies are performed by an endoscopist or endoscopy specialist in Singapore, a medical professional trained in gastroenterology, surgery, or other relevant fields. They use specialised instruments, such as an endoscope—a flexible tube with a light and camera attached—to view and operate on internal organs such as the lungs and stomach. 

Endoscopy specialists in Singapore diagnose, monitor, and sometimes treat conditions such as gastrointestinal bleeding, lung infections and gastric cancer. Patients undergoing endoscopy often find additional insights through gastroscopy screening in Singapore, which offers a more focused examination of the upper digestive tract.

Preparing For Your Appointment

Before The Appointment

Preparation for an endoscopy begins days before the actual procedure. Your endoscopy specialist will provide instructions based on the type of endoscopy you’re having.

To prepare for an endoscopy, inform your specialist about your medical history, including any allergies and all medications or supplements you take. Certain medications may need to be adjusted or temporarily discontinued.

You may need to follow a special diet a few days before the procedure, typically avoiding solid foods and sticking to clear liquids 24 hours before the endoscopy. You’ll need to cleanse your bowel for some types of endoscopy, especially colonoscopy. Clearing the bowel may involve taking a prescribed laxative solution to clear the intestines.

On The Day Of The Appointment

On the day of your endoscopy, ensure you follow all instructions meticulously. Most endoscopic procedures require fasting, so refrain from eating or drinking for at least 6 hours before the procedure.

Arrange for someone to drive you to and from the appointment, as sedatives or anaesthesia will be administered, impairing your ability to drive. Wear loose-fitting clothing to the appointment, as you may need to change into a hospital gown for the procedure.

The Endoscopy Procedure

What Happens During An Endoscopy

When you arrive for your endoscopy in Singapore, you’ll be greeted by the medical team and given an overview of the procedure. Here’s what typically happens:

  1. Preparation: You’ll change into a gown and be connected to devices that monitor your vital signs.
  2. Sedation: You’ll receive a sedative or anaesthesia to help you relax or sleep during the procedure.
  3. Insertion of the endoscope: The endoscope is gently inserted into your body through a natural opening, such as your mouth or rectum, depending on the type of endoscopy.
  4. Examination: The specialist uses the endoscope’s camera to examine the internal structures. Small instruments can be pushed through the endoscope to take tissue samples or perform minor treatments if necessary.
  5. Duration: The procedure usually takes 15 minutes to an hour, depending on its complexity.

Safety And Hygiene

Safety and hygiene are paramount in endoscopic procedures. The endoscope and all instruments are thoroughly sterilised to prevent infections. Doctors follow strict protocols to ensure a sterile environment and minimise any risk of complications.

Post-Procedure Care

Immediately After The Procedure

After the endoscopy, you’ll be taken to a recovery area, where the staff will observe you until the sedation wears off. Here’s what to expect:

  1. Observation: You’ll be observed for adverse reactions to the sedative or the procedure.
  2. Rest: It’s normal to feel groggy or sleepy. Rest until you feel alert enough to go home.
  3. Instructions: You’ll receive post-procedure care instructions, including dietary guidelines and activity restrictions.

Follow-Up

Follow-up care is essential to ensure proper recovery and address any findings from the endoscopy. Your endoscopy specialist in Singapore will discuss the results with you, often on the same day, if no biopsies were taken. If tissue samples were collected, it may take a few days to get the results. 

Contact your specialist if you experience severe pain, fever, vomiting, or any unusual symptoms after the procedure. Your endoscopy specialist may recommend additional tests, treatments, or lifestyle changes depending on the results. Patients interested in a complete digestive health check should consider both endoscopy and colonoscopy screening in Singapore, as these procedures collectively enhance the detection of early-stage gastrointestinal conditions.

If you experience excruciating pain during or after bowel movements, you might be suffering from an anal fissure. This condition can impact your daily life, making each trip to the bathroom uncomfortable.

Fortunately, anal fissures can be treatedIn this article, we discuss both surgical and non-surgical treatments for anal fissures, helping you make informed decisions about your well-being.

What Are Anal Fissures

Anal fissures are small tears in the anus lining that make bowel movements uncomfortable and painful. The pain may also be accompanied by itching, bleeding, and a visible tear in the skin around the anus. These fissures can affect anyone but are particularly common in adults aged 15 to 40.

Anal fissures are caused by:

  • Constipation: Hard, dry stools can cause tears as they pass through the anal canal.
  • Diarrhoea: Frequent loose or watery stools can irritate and tear the anal lining.
  • Childbirth: Women may develop fissures due to the strain of delivery.
  • Anal Intercourse: This can cause trauma to the anal lining.
  • Underlying Conditions: Conditions like Crohn’s disease can cause chronic inflammation of the intestines, leading to fissures.

Non-Surgical Treatment Options

Most anal fissures can be managed with non-surgical treatments, especially if addressed early. Here are some effective non-surgical options.

Dietary Changes

Changing your diet is one of the simplest ways to treat and prevent anal fissures. Key dietary changes you can implement include:

  • High-Fibre Foods: Incorporate fruits, vegetables, whole grains, and legumes for softer stools and make them easier to pass.
  • Hydration: Drinking plenty of water helps keep stools soft.
  • Avoiding Irritants: Limit intake of spicy foods, caffeine, and alcohol, which can irritate the digestive tract.

Medications

You can manage symptoms and promote healing of anal fissures with medication. These include:

  • Stool Softeners: Over-the-counter stool softeners can ease bowel movements.
  • Topical Anaesthetics: Creams or ointments containing lidocaine can reduce pain.
  • Nitrate Ointments: These help relax the anal sphincter and enhance blood circulation to the area, promoting healing.
  • Calcium Channel Blockers: Applied topically, these medications relax the anal sphincter muscles.

Sitz Baths

A sitz bath means sitting in warm water for 10-20 minutes several times daily, particularly after bowel movements. The warmth can soothe pain and itching, while increased blood flow to the area aids in healing. Regular sitz baths will also help maintain hygiene and prevent infection.

Lifestyle Modification

Changing your lifestyle can also support the healing process and prevent recurrence. Consider the following:

  • Regular Exercise: Being physically active can help prevent constipation and promote digestive health.
  • Proper Bowel Habits: Avoid straining during bowel movements, and go to the bathroom when you feel the urge.
  • Good Hygiene: Gently clean the anal area with water, and pat dry after bowel movements.

Surgical Treatment Options

If non-surgical treatments fail to heal the anal fissure or if it becomes chronic, your doctor may recommend surgery. Understanding the preparatory steps for anal fissure surgery in Singapore is crucial for a successful outcome.

Lateral Internal Sphincterotomy

Lateral internal sphincterotomy is the most common surgical procedure for treating anal fissures. This surgery has a high success rate, relieving pain and promoting healing. A small cut is made in the internal anal sphincter muscle. The cut helps reduce the muscle tension, allowing the fissure to heal.

Non Surgical Alternatives

  • Botox Injections: Botulinum toxin can be injected into the anal sphincter to paralyse the muscle, reducing spasms and pain temporarily.

Post-Surgery And Recovery

After surgery, proper care and adherence to recovery guidelines are essential:

  • Pain Management: Pain is usually minimal after surgery but can be managed with prescribed medications.
  • Wound Care: Clean the surgical site and keep it dry, and follow your surgeon’s instructions for wound care.
  • Diet: Continue a high-fibre diet and stay hydrated to prevent constipation.
  • Activity: Avoid straining yourself for a few weeks, but do light exercise as your doctor recommends.
  • Follow-up: Attend all follow-up appointments to ensure proper healing.

How To Choose The Proper Treatment

Choosing the right treatment for anal fissures depends on the severity of the fissure, your overall health, and your response to initial treatments. If you’re trying to understand your symptoms, our explanation on anal fissures vs fistulas and their causes might help clarify your doubts.

It is best to speak to your healthcare provider about your symptoms and treatment options so you can discuss which treatment option is suitable for you. It’s essential to understand the recovery timeline if you opt for anal fissure surgery in Singapore. If distinguishing between an anal fissure and haemorrhoid seems challenging, our blog provides a clear explanation of the four main differences.

Colon cancer and treatments in Singapore

Colon cancer, a malignancy of the large intestine, is a significant health concern in Singapore. Given its increasing prevalence and the complexities involved in its treatment, it’s crucial to understand the disease, its progression stages, and the various treatment options available. 

In Singapore, continuous improvements in colon cancer treatment protocols reflect the country’s commitment to medical excellence and patient care. This article provides an in-depth look at colon cancer, focusing on the stages of the disease, factors influencing treatment decisions and the support necessary for patients.

What Is Colon Cancer?

Colon cancer originates in the large intestine (colon), which is the final part of the digestive tract. It typically starts as small, noncancerous clumps of cells called polyps that form on the inside of the colon. Over time, some of these polyps can become colon cancers. Emphasising early detection, Singapore colorectal cancer screening programs are designed to identify precancerous conditions before they develop into full-blown cancer.

While the exact cause of colon cancer is not entirely understood, several risk factors have been identified, including age, a family history of the disease, certain genetic mutations, a diet high in red and processed meats, and lifestyle factors such as smoking and physical inactivity. With ongoing research and clinical trials, colorectal cancer treatment in Singapore continues to evolve, offering new hopes for better outcomes.

The Stages Of Colon Cancer

Colon cancer is classified into stages based on the extent of its spread. Understanding these stages is critical for determining the appropriate treatment strategy. Recognizing the signs can be crucial for catching potential issues early, enabling timely medical intervention and increasing the chances of a favourable outcome.

Stage 0 – Carcinoma In Situ

Stage 0, also known as carcinoma in situ, is the earliest form of colon cancer. At this stage, the cancerous cells are confined to the innermost layer of the colon’s lining and have not invaded deeper tissues or spread to other parts of the body. This stage is typically highly treatable, often through surgery to remove the localised area of abnormal cells.

Stage 1 – Early Stage Colon Cancer

In Stage 1, cancer has spread beyond the inner lining of the colon to the second and third layers of the colon wall, but it has not yet spread to the lymph nodes or distant sites. Treatment at this stage usually involves surgical resection of the affected section of the colon, often followed by a comprehensive monitoring plan to ensure that the cancer does not return.

Stage 2 – High-Risk Early Stage

Stage 2 colon cancer is more advanced, as the cancer has penetrated through the colon wall and may have reached nearby tissues but has not spread to the lymph nodes. It is further divided into sub-stages:

 

    • Stage IIA: Cancer has spread through the muscle layer to the outermost layers of the colon or rectum.

    • Stage IIB: Cancer has grown through the outermost layer but hasn’t reached nearby organs.

    • Stage IIC: Cancer has grown through the outermost layer and into nearby structures.

Treatment for Stage 2 typically involves surgery to remove the tumour, possibly followed by chemotherapy, especially if there are high-risk features such as poorly differentiated cells or lymphovascular invasion.

Stage 3 – Regional Spread

At Stage 3, cancer has spread to nearby lymph nodes but not to other parts of the body. This stage is divided into three subcategories based on the number of affected lymph nodes and the extent of tumour invasion:

 

    • Stage IIIA: Cancer has spread to up to three nearby lymph nodes and has penetrated the muscle layer.

    • Stage IIIB: Cancer has spread to up to four to six nearby lymph nodes or into surrounding tissues.

    • Stage IIIC: Cancer has spread to seven or more nearby lymph nodes but not to distant organs.

Treatment usually involves a combination of surgery, chemotherapy, and sometimes radiation therapy to address the cancer’s spread to lymph nodes.

Stage 4 – Metastatic Colon Cancer

Stage 4, or metastatic colon cancer, is the most advanced stage. Cancer has spread to distant organs such as the liver, lungs, or distant lymph nodes. This stage is further classified based on the extent and number of distant metastases:

 

    • Stage IVA: Cancer has spread to one distant organ.

    • Stage IVB: Cancer has spread to more than one distant organ or area.

    • Stage IVC: Cancer has spread to the peritoneum (the lining of the abdominal cavity).

Treatment for Stage 4 focuses on controlling the cancer and relieving symptoms. This may include a combination of surgery, chemotherapy, targeted therapy, and immunotherapy to extend life and improve quality of life.

Colorectal cancer screening in Singapore is regarded as a key preventive measure that is highly encouraged among adults over the age of 50.

Factors Influencing Treatment Decisions

While we have covered various treatments above based on the stages of cancer, there are other factors in play, too:

 

    • Patient’s overall health: Comorbidities and overall fitness can affect the choice of treatment.

    • Genetic mutations: Specific genetic profiles, such as those involving KRAS, NRAS, and BRAF mutations, can influence treatment options, particularly concerning targeted therapies.

    • Patient preferences: The patient’s quality of life, personal preferences, and treatment goals are essential in shaping the treatment plan.

Treatments

The treatment for colon cancer, as seen above, includes a variety of options. They may also be used in combination depending on the stage and characteristics of the cancer. Here are more details for each treatment:

 

    • Surgery: The primary treatment for early-stage colon cancer, involves the removal of the tumour and surrounding healthy tissue. Types of surgery include polypectomy, colectomy, and proctectomy.

    • Chemotherapy: Uses drugs to destroy cancer cells or stop them from growing. It is commonly used post-surgery in stages 2 and 3 and as a primary treatment for advanced stages.

    • Radiation therapy: Employs high-energy radiation to kill cancer cells or shrink tumours. Though it is used for colon cancer, it is more commonly used for rectal cancer.

    • Targeted therapy: Uses drugs or other substances to target specific molecules involved in cancer growth and spread. Commonly used drugs include cetuximab and bevacizumab.

    • Immunotherapy: Boosts the body’s natural defences to fight cancer. It is an option for certain advanced cancers that have specific genetic mutations or markers.

    • Palliative care: Focuses on relieving symptoms and improving the quality of life for patients with advanced cancer.

Supporting Patients Through Treatment

Supporting colon cancer patients involves a multidisciplinary approach that includes medical treatment, emotional support, and practical assistance.

 

    • Multidisciplinary care teams: These teams consist of oncologists, surgeons, radiologists, nurses, and social workers who collaborate to provide comprehensive care.

    • Patient education: Providing patients with detailed information about their diagnosis, treatment options, and side effects to empower them to make informed decisions.

    • Psychosocial support: Offering counselling services and support groups to help patients and their families cope with the emotional impact of cancer.

    • Financial assistance: Helping patients navigate financial resources and insurance options to ease the burden of treatment costs.

    • Rehabilitation services: Providing physical therapy and nutritional counselling to help patients recover and maintain their health during and after treatment.
