What Is Colorectal Cancer?

Cancer arising from the lining of the colon or rectum, often starting as non-cancerous polyps.

Why Do I Need Evaluation/Treatment?

You may have:

  • Blood in stool or change in bowel habits
  • Unexplained weight loss or fatigue
  • Family history of colorectal cancer

How Should I Prepare?

  • Bowel Prep: Clear-liquid diet 1–2 days before; prescribed laxative kit.
  • Medications: Continue most; inform us of blood thinners.
  • Consent: Review risks/benefits of colonoscopy or surgery.

What Happens During Diagnosis & Treatment?

  • Colonoscopy: Visualize and biopsy lesions.
  • Imaging: CT/MRI for staging.
  • Treatment:
    • Early stage: endoscopic polypectomy or EMR/ESD.
    • Localized cancer: surgical resection (colectomy) with lymph node removal.
    • Advanced disease: chemotherapy, radiotherapy, targeted therapy.

What Can I Expect Afterwards?

  • Recovery: Hospital stay 1–7 days post-surgery.
  • Diet: Gradual progression from liquids to solids.
  • Activity: Light walking immediately; avoid heavy lifting for 6 weeks.

Risks & Possible Complications

  • Bleeding or anastomotic leak (<5%)
  • Infection or deep-vein thrombosis
  • Bowel obstruction or altered bowel habits

Follow-Up

  • Surveillance colonoscopy at intervals based on stage.
  • CEA blood test every 3–6 months for 2 years, then annually.
