Posterior lateral omentum cancer refers to cancerous growths located in the posterior (back) and lateral (side) parts of the omentum. The omentum is a large fold of the peritoneum (the lining of the abdominal cavity) that hangs down from the stomach. While primary cancers of the omentum are rare, the omentum can be affected by metastatic (spread) cancers from other abdominal organs like the stomach, colon, or ovaries.
Anatomy of the Omentum
The omentum is divided into two main parts:
- Greater Omentum: Extends from the stomach and covers the intestines.
- Lesser Omentum: Connects the stomach to the liver.
Posterior Lateral Omentum refers to the back and side regions of the greater omentum. It plays a role in immune response and fat storage within the abdominal cavity.
Types of Omentum Cancer
- Primary Omentum Cancer: Originates in the omentum itself.
- Secondary (Metastatic) Omentum Cancer: Spreads to the omentum from other organs like the stomach, colon, or ovaries.
Primary omentum cancers are extremely rare and often classified under sarcomas or mesotheliomas.
Causes of Posterior Lateral Omentum Cancer
While the exact causes are not well-understood, several factors may contribute:
- Genetic Mutations: Changes in DNA can lead to uncontrolled cell growth.
- Environmental Factors: Exposure to certain chemicals or radiation.
