Colon Cancer

Colon cancer begins as a benign polyp that can transform into a malignant tumour over years.

Screening colonoscopy detects and removes precancerous polyps, while staging and multidisciplinary care guide curative surgery, chemotherapy, or combined therapies when needed.

Early-stage cases often have excellent outcomes; advanced disease benefits from individualized systemic and surgical strategies.

Overview And Clinical Background

Pathway from polyp to cancer

Most colon cancers develop slowly from adenomatous polyps in the large intestine.

Risk increases with age, family history, inflammatory bowel disease, and certain lifestyle factors.

PathogenesisProgression from adenoma to carcinoma driven by stepwise genetic changes.
Risk factorsAge, family history, smoking, obesity, low-fiber diet, and IBD.
Screening importanceColonoscopy detects and removes precancerous polyps before they become cancer.

Symptoms, Signs And Presentation

Early colon cancer may be silent.

Symptoms usually appear once the tumour affects bowel function or bleeds.

Bleeding or anemiaOccult or visible blood in stool leading to iron-deficiency anemia.
Bowel habit changePersistent constipation, diarrhea, or altered stool calibre.
Obstructive signsCrampy abdominal pain, bloating, or blockage in advanced cases.

Diagnosis Methods And Investigations

Imaging, endoscopy and pathology

Diagnosis requires endoscopic visualisation and tissue biopsy, followed by imaging to stage the disease.

Accurate staging is essential to plan surgery and adjuvant therapy.

Colonoscopy and biopsyDirect visualisation with histology to confirm malignancy.
Cross-sectional imagingCT chest/abdomen/pelvis or MRI for local and distant staging.
Tumour markersCEA level for baseline and follow-up monitoring.

Treatment Options And Surgical Techniques

Curative treatment for localized colon cancer is surgical resection with adequate margins and lymph node removal.

Adjuvant chemotherapy reduces recurrence risk for selected stages.

Surgical resectionSegmental colectomy (open or laparoscopic) with lymphadenectomy.
Adjuvant therapySystemic chemotherapy for stage III and high-risk stage II disease.
Palliative optionsStenting, diverting stoma or systemic therapy for unresectable or metastatic disease.

Recovery, Risks And Prognosis

Recovery depends on surgery type; most patients resume normal activity within weeks.

Risks include infection, anastomotic leak, and bowel obstruction; prognosis relates to stage at diagnosis with early-stage disease often curable.
