*2.6.1 Assessing tumor high*

Rectal cancer can be divided (**Figure 6**) into: Low rectal cancer: Distal border is 0–5 cm from the anorectal angle. Mid rectal cancer: Distal border is 5–10 cm from the anorectal angle. High rectal cancer: Distal border is 10–15 cm from the anorectal angle. Involvement of the intersphincteric plane, external sphincter and levator

musculature should be assessed. Low cancer localization increases the risk of CRM engagement.
