Transverse rectal folds, also known as circular folds or plicae circulares, are normal anatomical structures within the rectum. They are wrinkles or ridges that help slow down the passage of stool, allowing for better absorption of water and nutrients. In the context of rectal cancer, these folds can be areas where tumors may develop or grow, potentially affecting the rectum’s function.
Rectal cancer is a type of cancer that begins in the rectum—the final several inches of the large intestine before the anus. When cancer starts in the rectum, it often begins as small, noncancerous clumps of cells called polyps that form on the inner wall. Over time, some of these polyps can become cancerous.
Key Points:
- Location: Rectal cancer occurs in the last part of the large intestine.
- Development: Often starts from polyps, which can turn into cancer.
- Impact: Can affect bowel habits and overall digestive health.
Anatomy of the Rectum
Structure
The rectum is a muscular tube about 12 centimeters long. It connects the colon to the anus and serves as a temporary storage site for feces before elimination.
Blood Supply
- Superior Rectal Artery: Supplies the upper part of the rectum.
- Middle Rectal Artery: Supplies the middle portion.
- Inferior Rectal Artery: Supplies the lower part near the anus.
Nerve Supply
- Autonomic Nervous System: Controls involuntary functions like bowel movements.
- Pudendal Nerve: Provides sensation to the anal region.
Understanding the anatomy is crucial for diagnosing and treating rectal cancer effectively.
Types of Rectal Cancer
Rectal cancer can be classified based on how deeply the cancer has penetrated the rectal wall and whether it has spread to other parts of the body.
- Adenocarcinoma: The most common type, originating from glandular cells.
- Carcinoid Tumors: Develop from hormone-producing cells.
- Gastrointestinal Stromal Tumors (GISTs): Arise from connective tissue.
- Lymphoma: Begins in the immune system’s cells.
- Sarcoma: Originates from muscle or connective tissue.
Each type has different characteristics and treatment approaches.
Causes of Transverse Rectal Folds Cancer
While the exact cause of rectal cancer is not known, several risk factors can increase the likelihood of developing it. Here are 20 potential causes and risk factors:
- Age: Most common in people over 50.

- Genetic Disorders: Such as familial adenomatous polyposis (FAP) and Lynch syndrome.
- Personal History: Previous colorectal cancer or polyps.
- Inflammatory Bowel Disease: Including Crohn’s disease and ulcerative colitis.
- Diet: High in red or processed meats.
- Lifestyle Factors: Lack of physical activity, obesity, smoking, and heavy alcohol use.
