Conditions/Oncologic surgery
Colon Cancer
Diagnosis, surgery, and multidisciplinary care
When found early, outcomes can be excellent; surgery remains central for most localized disease.
Colon cancer often arises from adenomatous polyps and can be prevented or caught early with colonoscopy. Early disease may be silent; bleeding, anemia, habit change, or weight loss deserve investigation rather than a long “hemorrhoid” assumption. Treatment depends on stage and may include open, laparoscopic, or robotic colectomy with appropriate lymph-node clearance, plus chemotherapy when indicated. MMR/MSI testing at new diagnosis informs immunotherapy eligibility and Lynch syndrome evaluation. Metastatic planning uses RAS/BRAF and selected HER2/NTRK results — not a one-size package before staging is clear.

Key points for patients
- MMR / MSI at diagnosisTap for details · key note insideNoteThis result can change both systemic options and hereditary counseling.
Universal MMR/MSI evaluation is considered at new colorectal diagnosis — not only in young patients. The result can change both systemic options and hereditary counseling.
- Metastatic biomarkersTap for details
In metastatic disease, RAS/BRAF and selected HER2/NTRK testing guide targeted therapy. Ordering every possible test without a clinical question is not the goal.
- Surgical routesTap for details
Approach is chosen by anatomy, emergency status, prior surgery, and experience — not by marketing labels. Oncologic margins and node harvest remain the standard regardless of open or minimally invasive access.
- Warning symptomsTap for details · key note inside
Rectal bleeding, iron-deficiency anemia, persistent habit change, or unexplained weight loss — especially after age 40 — should prompt colonoscopy, not prolonged self-labeling as hemorrhoids.
- After resectionTap for details
Early mobilization, pain control, and staged diet support recovery. Pathology and board decisions then set adjuvant therapy or surveillance.
