Upper rectum cancer is a type of colorectal cancer that starts in the upper part of the rectum, which is the final section of the large intestine before the anus. Understanding its anatomy, causes, symptoms, and treatment options can help in early detection and effective management.
Anatomy of the Upper Rectum
Structure
- Rectum Location: The upper rectum is located just above the middle rectum and extends from about 10-15 centimeters from the anus.
- Function: It stores stool before it passes into the anal canal for elimination.
Blood Supply
- Superior Rectal Artery: Supplies blood to the upper rectum.
- Inferior Rectal Artery: Supplies the lower rectum.
Nerve Supply
- Autonomic Nerves: Control involuntary functions like blood flow and muscle contractions.
- Somatic Nerves: Control voluntary movements of the pelvic muscles.
Types of Upper Rectum Cancer
- Adenocarcinoma: Most common type, originating from glandular cells.
- Squamous Cell Carcinoma: Rare, arises from squamous cells.
