Why Do Ovarian Cancer Symptoms Present Like Gi Problems?

Ovarian cancers or ovarian neoplasms occur in the abdominal area.
This cavity, the abdominal cavity, is also referred to as the peritoneal cavity because during embryogenesis the peritoneum (a sheath of tissue) lines the abdomen and all its contents.
This would include the ovaries.
Now, there is a complex system of nerves that innervate the abdominal viscera (the layer of fibrous like tissue that is directly ontop of the organs in the abdomen).
When these nerves are in anyway irritated, which would include blunt trauma, inflammation, and even cancers in the abdomen, etc . . . then the patient will present with pain in the abdomen as well as pain elsewhere in the body (called referred pain).
The pain elsewhere in the body is due to the innervation of the viscera which refers pain elsewhere, for example you have appendicitus but the pain is all over the abdomen at the early stages.
Now, in cancer, particularly ovarian cancer, the tumor can spread throughout the visceral peritoneum or the parietal peritoneum.
Given the location of the ovaries to the GI system, a tumor (be it benign or metastatic in nature) can physically push aside tissues and cause blockage by pinching off the passage way in the GI tract.
Moreover, if it had spread to the GI, there could likely be a GI bleed or visceral peritoneal bleed, or ovarian visceral peritoneal bleed or tissue in the GI or ovary that bleeds.
This could present as blood in the stool (GI bleed) or hardening in the abdomen on palpation.
In almost all cases, there will be pain within the abdominal area.
There are many other problems associated with this cancer type which include condition of: tenesmus (the sensation of having the need to go poop but cannot), ascites, discoloration of the stool, anorexia, anemia (due to bleeding), etc.

Why Do Ovarian Cancer Symptoms Present Like Gi Problems?

Gastrointestinal (GI) symptoms such as heartburn, indigestion/dyspepsia, bloating and constipation are common in the community. However, these symptoms may be misinterpreted and their impact and significance misunderstood both by health care providers and patients. The ACG has created this special resource section that features the College?s wealth of scientifically-based education material and information, the latest related research from The American Journal of Gastroenterology and expert insight to help patients understand common GI symptoms and how these symptoms should be appropriately and effectively managed.
