This is a very rare form of cancer that affects the cells lining the inner side of the abdomen and covers the uterus, urinary bladder and the rectum.

Peritoneal cancer is different from abdominal cancer or ovarian cancer, as it originates in the peritoneal cells rather than spreading to the cells from other sites.

The cancer resembles ovarian cancer the most, as both the tissues are made of epithelial cells; as a result, both are treated in more or less the same way.


The causes of Peritoneal cancer are unknown, however some theories state that the cancer develops from the ovarian tissue implants left in the abdominal region during fetal development.

Some physicians also believe that the cancer is formed because the peritoneal cells resemble the ovarian cells the most.

Risk Factors

Peritoneal cancer is more likely to occur in women than in men.

Also, age plays an important factor in the chances of contracting peritoneal cancer.


  • Abdominal discomfort, indigestion, swelling, pain from gas, bloating, pressure or cramps
  • Nausea, diarrhea
  • Constipation, frequent urination
  • Loss of appetite
  • Sudden weight gain or loss
  • Abnormal vaginal bleeding or discharge
  • Bleeding from rectum
  • Shortness of breath


Peritoneal cancer is diagnosed using the following techniques

  • Complete physical examination of the pelvic organs.
  • Blood tests
  • Biopsy of peritoneal tissue
  • Ultrasound scans


Treatment of the cancer depends on the stage of the cancer, size of the tumor and the age and overall health of the patient.

Surgical methods are used to remove the cancerous cells, and are the most effective. However, the doctor may remove the ovaries, Fallopian tubes and/or the uterus.

Chemotherapy and radiation therapy may also be used to treat the condition, by using chemicals and focused high energy radiations to destroy the cancerous cells.

Post Treatment

A cancer can be emotionally and physically strenuous for the patient, and it is important for the family members to provide sufficient backing during and after the treatment procedure.

After surgical treatment, often the patient is rendered infertile due to removal of one or more of the pelvic organs.

In case of major surgeries, the recovery period is considerably higher.Any abnormal discharge, bleeding or abdominal pain after the treatment procedure should be reported immediately to the doctor.
