Overview

Colorectal cancer, also known as bowel cancer, originates in the colon or rectum. It typically starts as benign polyps that can develop into cancer over time. Colorectal cancer is one of the most common cancers worldwide and can affect both men and women, especially those over 50 years old.

Signs and Symptoms

The symptoms of colorectal cancer can vary and might not be noticeable in the early stages. Common signs and symptoms include:

• Changes in bowel habits (diarrhea, constipation, or narrowing of the stool)
• Blood in the stool (bright red or very dark)
• Rectal Bleeding
• Persistent abdominal discomfort (cramps, gas, or pain)
• Feeling that the bowel does not empty completely
• Weakness or fatigue
• Unexplained weight loss
• Iron Deficiency Anemia

Types

Colorectal cancer is classified based on the location and characteristics of the cancer cells:

• Adenocarcinomas: The most common type, originating in mucus-producing glandular cells.
• Carcinoid Tumors: Develop in hormone-producing cells in the intestines.
• Gastrointestinal Stromal Tumors (GISTs): Rare tumors starting in the connective tissue of the colon.
• Lymphomas: Cancers of the immune system cells that can start in the colon or rectum.
• Sarcomas: Rare tumors that start in the blood vessels, muscle layers, or other connective tissues of the colon.
• Melanomas: These skin cancers can rarely develop in the rectum.

Diagnosis

Diagnosing colorectal cancer involves several tests and procedures:

• Colonoscopy: Examination of the entire colon and rectum using a long, flexible tube with a camera.
• Sigmoidoscopy: Similar to a colonoscopy but only examines the rectum and lower colon.
• Stool Tests: Detect blood or DNA changes in stool samples.
• CT Colonography (Virtual Colonoscopy): Uses CT scans to create detailed images of the colon and rectum.
• Imaging Studies: Imaging tests such as computed tomography (CT) scans, magnetic resonance imaging (MRI), or positron emission tomography (PET) scans.
• Biopsy: Removal of a tissue sample during a colonoscopy to check for cancer cells.
• Blood Tests: Faecal Occult Blood Test (FOBT) or Fecal Immunochemical Test (FIT) These tests detect blood in the stool, which can be a sign of colorectal cancer or precancerous polyps.
• Stool DNA Test: This test detects specific DNA markers associated with colorectal cancer and precancerous polyps. It may be used as an alternative to colonoscopy in certain cases.

Treatment

Surgical options depend on the stage and location of the cancer:

Surgery

• Polypectomy and Local Excision: Removal of polyps or small, localized cancers during a colonoscopy.
• Partial Colectomy: Removal of the cancerous part of the colon or rectum and nearby lymph nodes.
• Colostomy: Creation of an opening (stoma) in the abdominal wall to allow waste to leave the body, sometimes necessary if the rectum is removed.
• Minimally Invasive Surgery: Robotic Laparoscopic surgery involves smaller incisions and a faster recovery.

Other Treatments

• Radiation Therapy: Uses high-energy rays to destroy cancer cells, often used before or after surgery. It may be used alone or in combination with chemotherapy, either before or after surgery.
• Chemotherapy: Uses drugs to kill cancer cells or stop them from growing, often used in combination with other treatments. It may be given before surgery (neoadjuvant chemotherapy) to shrink the tumor, after surgery (adjuvant chemotherapy) to reduce the risk of recurrence, or as the primary treatment for advanced colorectal cancer.
• Targeted Therapy: Uses drugs to target specific molecules involved in cancer growth. Drugs like cetuximab and bevacizumab may be used in combination with chemotherapy to treat advanced colorectal cancer.
• Immunotherapy: Boosts the body's immune system to fight and attack cancer.

Meditation

Meditation and other complementary therapies can support the overall well-being of patients undergoing cancer treatment. Techniques such as mindfulness, deep breathing, and guided imagery can help reduce stress, anxiety, and pain.

Colorectal Cancer Prevention

Reducing the risk of colorectal cancer involves implementing various strategies. Here are key approaches:

• Undergo regular screening tests such as colonoscopy to detect colorectal cancer early, when treatment is most effective. Consult your healthcare provider for screening guidelines.
• Maintain a balanced diet rich in fruits, vegetables, and whole grains. Regular exercise and avoiding smoking and excessive alcohol consumption are also essential.
• Manage weight effectively through diet and exercise to lower your risk.
• Moderate or eliminate alcohol consumption, and quit smoking to reduce your risk.
• Some studies suggest that aspirin or NSAIDs may lower colorectal cancer risk, but consult with a healthcare provider before starting any new medications.
• Effectively manage inflammatory bowel diseases like Crohn's disease and ulcerative colitis to reduce the risk of colorectal cancer.
• Individuals with a family history of colorectal cancer may benefit from genetic counseling and testing to develop personalized prevention strategies.

Frequently Asked Questions (FAQ)

What are the risk factors for colorectal cancer?

Risk factors include age, family history, inflammatory bowel disease, a diet high in red or processed meats, smoking, and heavy alcohol use.

How can colorectal cancer be prevented?

Preventative measures include regular screenings, maintaining a healthy diet, regular exercise, avoiding tobacco, and limiting alcohol consumption.

What is the prognosis for colorectal cancer?

Prognosis depends on the stage at diagnosis, with early detection significantly improving outcomes.

Are there any genetic factors involved in colorectal cancer?

Yes, genetic conditions such as Lynch syndrome and familial adenomatous polyposis (FAP) increase the risk of colorectal cancer.

What are the common treatments for colorectal cancer?

Common treatments include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy.
