Greater omentum cancer is a rare form of cancer that affects the greater omentum, a significant part of the abdominal anatomy. This guide aims to provide a clear and comprehensive overview of greater omentum cancer, including its anatomy, types, causes, symptoms, diagnostic methods, treatments, prevention strategies, and frequently asked questions.
The greater omentum is a large fold of fatty tissue that drapes over the intestines inside your abdomen. It plays several roles, including:
- Protection: Shields abdominal organs from infections and injuries.
- Fat Storage: Stores fat and helps in insulating the body.
- Immune Response: Contains immune cells that fight infections.
- Healing: Assists in healing after abdominal surgeries or injuries.
Understanding the greater omentum’s structure and function is essential to grasp how cancer can affect it.
Greater omentum cancer refers to malignant tumors that develop in the greater omentum. These cancers can arise from the omental tissue itself or spread (metastasize) from other organs like the stomach, colon, or ovaries.
Key Points:
- Rare Condition: Greater omentum cancer is uncommon compared to other abdominal cancers.
- Primary vs. Secondary: Primary cancers originate in the omentum, while secondary cancers spread from other organs.
- Diagnosis and Treatment: Due to its rarity, diagnosing and treating omental cancer can be challenging.
Anatomy of the Greater Omentum
Understanding the anatomy of the greater omentum helps in comprehending how cancer affects it.
Structure:
- Location: Lies between the stomach and the transverse colon.
- Composition: Made up of fat, blood vessels, lymph nodes, and immune cells.
- Extensions: Can extend to other parts of the abdomen, providing a protective layer.
Functions:
- Fat Storage: Acts as a fat reservoir.
- Protection: Shields organs from infections and physical trauma.
- Immune Defense: Contains immune cells that help fight infections and heal wounds.
- Isolation of Infections: Can wall off infections within the abdominal cavity.
