Colon Cancer

Colon cancer does not affect everyone equally. Certain factors raise an individual's risk, and knowing these helps us have more targeted conversations with patients who may benefit from earlier screening.

• Age over 45 — the risk increases significantly from mid-life onward, though we are seeing presentations in younger adults with greater frequency than before
• A diet high in red or processed meat and low in fibre, vegetables, and whole grains is consistently associated with higher colorectal cancer risk
• A personal or family history of colorectal polyps or cancer — if a first-degree relative has had colon cancer, your own risk is meaningfully elevated
• Inflammatory bowel disease — patients with long-standing Crohn's disease or ulcerative colitis carry a higher lifetime risk of colorectal cancer
• Type 2 diabetes and obesity — both are independent risk factors and are becoming more prevalent across urban Uganda
• Smoking and heavy alcohol use — each contributes to cellular damage in the bowel lining over time
• Physical inactivity — a sedentary lifestyle is associated with a higher risk, independent of diet and weight

Colon cancer in its early stages produces no symptoms that most people would recognize as significant. By the time patients come to us with clear complaints - blood in the stool, unexplained weight loss, a persistent change in bowel habit - the disease has often progressed to a stage that requires more complex treatment.

At UMC Victoria Hospital, a leading colon cancer hospital in Uganda, we advise adults over 45 with no specific risk factors to discuss screening with their doctor. For those with a family history of colon cancer or polyps, we would typically recommend starting earlier - from age 40, or ten years before the age at which a close relative was diagnosed, whichever comes first.

• Colonoscopy
  is the most thorough screening method. It allows direct visualization of the entire colon and the removal of polyps before they become malignant - combining detection and prevention in a single procedure
• Faecal occult blood testing
  is a non-invasive option that checks for blood in the stool not visible to the naked eye. A positive result warrants a follow-up colonoscopy
• Flexible sigmoidoscopy
  examines the lower section of the colon and may be used in specific situations where a full colonoscopy is not immediately available

Many patients with early colon cancer have no symptoms at all, which is why screening matters. These include:

• A persistent change in bowel habits - more frequent stools, looser stools, or constipation that has no clear explanation and lasts more than a few weeks
• Blood in the stool, whether bright red or darker in colour - this always warrants investigation
• Abdominal discomfort, cramping, or a sense of bloating that does not resolve
• A feeling that the bowel has not emptied after passing stool
• Unintended weight loss over weeks without a change in diet or activity
• Fatigue and pallor - these may indicate anaemia from slow, ongoing blood loss from the bowel
• Severe abdominal pain, inability to pass stool, or vomiting

If you or a family member has noticed any of these symptoms - particularly blood in the stool or unexplained weight loss, seek emergency medical care.

We approach diagnosis systematically, beginning with a detailed history and examination. From there, the investigations we recommend depend on symptom pattern, age, and risk profile.

• Colonoscopy
  is our primary diagnostic tool. It provides direct visualization of the colon lining, allows biopsy of any suspicious areas, and enables removal of polyps during the same procedure
• CT colonography
  offers a non-invasive alternative for patients who are not suitable candidates for colonoscopy, producing detailed cross-sectional images of the colon
• Biopsy and histopathology
  — tissue samples taken during colonoscopy are analysed to confirm whether cancer cells are present and to characterize the tumour type
• CT scan of the chest, abdomen, and pelvis
  is used for staging to determine whether the cancer has spread beyond the colon to lymph nodes or other organs
• Blood tests, including CEA (carcinoembryonic antigen)
  may be used alongside imaging to support staging and to track response to treatment over time

Treatment depends on the stage at which the cancer is identified. When caught early, Colon Cancer is highly curable. Even at more advanced stages, effective treatment is available that can extend life and improve quality of life significantly.

• Surgery
  is the primary treatment for localized Colon Cancer. We perform colectomy - removal of the affected section of colon - with the goal of clear margins. In many cases, the bowel can be rejoined without a permanent colostomy
• Laparoscopic (keyhole) surgery
  is available for suitable candidates, offering faster recovery and smaller incisions compared to open surgery
• Chemotherapy
  is used after surgery in certain stages to reduce the risk of recurrence, or before surgery to shrink a tumour in more advanced cases
• Targeted therapy and immunotherapy
  are increasingly used for advanced or metastatic Colon Cancer, particularly in tumours with specific molecular profiles identified through biopsy analysis
• Palliative care and symptom management
  form an important part of our approach for patients with advanced disease - focusing on comfort, function, and quality of life alongside active treatment

Our Gastroenterology and GI Surgery team at UMC Victoria Hospital in Kampala provides coordinated, specialist care for Colon Cancer treatment in Uganda.

  for both diagnostic and therapeutic procedures under one roof
• Multidisciplinary case review
  ensuring each patient's treatment plan is informed by specialist input across surgery, oncology, and pathology
• Structured follow-up and surveillance
  after treatment, to monitor recovery and detect any recurrence at the earliest opportunity
