About Bowel Cancer-Peritoneal-Metastases 770

Peritoneal Metastases

All the organs in the abdomen are contained inside a big sac or membrane called the peritoneum.
 
Bowel cancer can spread through blood and lymph circulation, or it can spread directly inside this sac if a tumour grows through the bowel wall before it is diagnosed.
 
Cancer cells can break off from the main tumour and escape into the abdomen, lodging between the lining (the peritoneum) and the other organs or tissues that are contained there.
