Bowel Cancer Comprehensive Guide

What is Bowel Cancer?

Bowel cancer, also known as colorectal cancer, is a type of cancer that begins in the colon or rectum. It occurs when cells in the bowel grow uncontrollably, forming a tumor that can invade nearby tissue and spread to other parts of the body.

Classification of Bowel Cancer

Type: Malignant cancer.
Classification Explanation: Bowel cancer is classified as a malignant tumor due to its potential to spread and invade other tissues.

Types of Bowel Cancer

Adenocarcinomas: The most common type, starting in glandular cells of the bowel lining.
Squamous Cell Carcinoma: Arises from squamous cells in the bowel.
Carcinoid Tumors: Originates from hormone-producing cells in the bowel.
Lymphomas and Sarcomas: Rare, starting in lymph tissue or connective tissue.

Bowel Cancer Health Signs and Symptoms

Changes in bowel habits (e.g., diarrhea, constipation)
Blood in stool
Persistent abdominal pain or cramping
Unexplained weight loss
Fatigue or weakness

Body Parts Affected by Bowel Cancer

Colon
Rectum
Surrounding lymph nodes and potentially other organs through metastasis

Bowel Cancer Causes

Genetic predispositions (e.g., Lynch syndrome, familial adenomatous polyposis)
Lifestyle factors (high red/processed meat intake, low fiber)
Obesity, smoking, and heavy alcohol use
Age (higher risk after 50)

Bowel Cancer Stages

Early Stage: Cancer limited to the bowel lining.
Intermediate Stage: Cancer has invaded the muscle layer of the bowel wall.
Advanced Stage: Cancer has spread to nearby lymph nodes or distant organs.

How to Prevent Bowel Cancer

Maintain a high-fiber, low-fat diet with fruits, vegetables, and whole grains.
Limit red and processed meat intake.
Exercise regularly, avoid smoking, and moderate alcohol consumption.
Get regular screenings, especially if you have a family history of bowel cancer.

Bowel Cancer Diagnosis

Diagnosis involves reviewing symptoms, family history, and performing tests like colonoscopies and imaging.

Testing for Bowel Cancer

Colonoscopy: Examines the entire colon and rectum for polyps or tumors.
Sigmoidoscopy: Examines the lower part of the colon.
Fecal Occult Blood Test (FOBT): Detects hidden blood in stool.
CT Colonography: A CT scan specifically for the colon.
Biopsy: Confirms cancer by analyzing tissue samples.

Health Professionals Who Treat Bowel Cancer

Gastroenterologists: Experts in digestive diseases, handle initial diagnosis.
Oncologists: Specialists in cancer treatment, including chemotherapy and radiotherapy.
Colorectal Surgeons: Perform surgeries to remove tumors or affected bowel sections.

Reasons to See a Bowel Cancer Health Professional

Persistent changes in bowel habits
Blood in stool or unexplained weight loss
Family history of colorectal cancer or genetic predisposition

Process to Find the Right Bowel Cancer Treatment

Consult with oncologists and gastroenterologists to determine cancer stage and appropriate treatment options.

Preparing to See a Specialist

Bring detailed notes on symptoms, family history, and a list of current medications.
Prepare any previous test results or medical records.

Questions to Ask Your Doctor

What stage is my cancer, and what are my treatment options?
Are there any clinical trials available for my case?
How will treatment impact my daily life?
What lifestyle changes should I consider?
How will my treatment be monitored over time?

Types of Treatments for Bowel Cancer

Surgery: Removal of cancerous sections of the bowel.
Chemotherapy: Targets and kills cancer cells.
Radiotherapy: Uses radiation to shrink or destroy tumors.
Targeted Therapy: Focuses on specific cancer cells without affecting healthy cells.
Immunotherapy: Boosts the body’s natural defenses to fight cancer.

Bowel Cancer Checkups, Tests, and Examinations

Regular follow-ups with colonoscopy, imaging, and blood tests (e.g., CEA tests for cancer markers).
Periodic physical exams to monitor for signs of recurrence.

Bowel Cancer Clinical Trials

Clinical trials on new targeted therapies, immunotherapy drugs, and minimally invasive surgeries.
Studies on the effects of diet and exercise on recovery and recurrence.

How to Monitor Bowel Cancer

Routine blood tests for cancer markers.
Stool tests and regular colonoscopies post-treatment.
Monitoring devices for tracking treatment side effects.

Managing Bowel Cancer – Living with Bowel Cancer

Bowel Cancer Facts & Stats:

Prevalence and Incidence:

Incidence: Each year in the UK, approximately 42,900 people are diagnosed with bowel cancer. This is more than 115 people every day. (Source: Cancer Research UK)
Prevalence: As of 2017, it is estimated that around 363,000 people in the UK who are alive have been diagnosed with bowel cancer at some point in their lives. (Source: Macmillan Cancer Support)

Risk Factors and Prevention:

Risk Factor (Age): Over 90% of people diagnosed with bowel cancer in the UK are aged 50 and over. (Source: Cancer Research UK)
Risk Factor (Diet): A diet high in red and processed meat and low in fibre can increase the risk of bowel cancer. It’s estimated that around 13% of bowel cancer cases in the UK are linked to processed and red meat consumption. (Source: World Cancer Research Fund International)
Prevention (Screening): Regular bowel cancer screening can detect the condition at an earlier, more treatable stage and can also find and remove polyps (small growths in the bowel) which can become cancerous. For people aged 60 to 74 in England, Scotland and Wales, bowel cancer screening is offered every two years. In 2022-23, the uptake rate for the bowel cancer screening programme in England was around 60%. (Source: NHS England)

Mortality and Morbidity:

Mortality: Bowel cancer is the second most common cause of cancer death in the UK, accounting for around 16,800 deaths each year. (Source: Cancer Research UK)
Survival: More than 50% of people diagnosed with bowel cancer in England survive their cancer for ten years or more. Survival rates are higher when the cancer is diagnosed at an earlier stage. (Source: Cancer Research UK)
