Lesser Omentum Cancer

Lesser omentum cancer is a rare type of cancer that affects the lesser omentum, a thin layer of tissue in the abdomen. This guide provides detailed information about its anatomy, types, causes, symptoms, diagnostic tests, treatments, prevention, and frequently asked questions (FAQs). Whether you’re seeking information for yourself or a loved one, this article aims to present everything in simple, easy-to-understand language

Anatomy of the Lesser Omentum

The lesser omentum is a double layer of peritoneum (the lining of the abdominal cavity) that connects the stomach and the first part of the small intestine (duodenum) to the liver. It plays a role in supporting the organs in the upper abdomen and contains blood vessels, nerves, and lymphatics that supply these organs.

Function

• Support: Helps hold the stomach and liver in place.
• Pathway for Vessels: Contains important blood vessels that supply the stomach and liver.
• Fat Storage: Stores fat that can be used for energy.

Types of Lesser Omentum Cancer

Lesser omentum cancer can be categorized based on the type of cells involved and the specific location within the lesser omentum. The main types include:

1. Carcinoma: Cancer that starts in epithelial cells, which line the surfaces of organs.
2. Sarcoma: Cancer that originates in connective tissues like fat, muscle, or blood vessels.
3. Lymphoma: Cancer that begins in the lymphatic system within the lesser omentum.
4. Metastatic Cancer: Cancers that have spread to the lesser omentum from other parts of the body, such as the stomach, colon, or pancreas.
