Abdominal discomfort, feeling of fullness, constipation and loss of appetite are some of the symptoms of primary peritoneal cancer, according to WebMD. The patient may also experience abnormal vaginal bleeding, rectal bleeding and unexplained weight loss or gain.
In the early stages, symptoms of primary peritoneal cancer are very vague, according to USCF Medical Center. By the time the patient presents any symptoms, the primary peritoneal cancer is often advanced. The symptoms are also very similar to those of ovarian cancer.
The most common symptoms are abdominal pain and distention, reports the PubMed Central. The patient may experience general abdominal discomfort such as bloating, gas, pressure, cramps and swelling, states USCF Medical Center. They may feel full, even after consuming a light meal. These symptoms may be due to a buildup of fluid in the abdomen, also known as ascites, explains WebMD.
Patients may experience changes in bladder or bowel habits, reports the Center for Cancer and Blood Disorders. They may feel the need to urinate more often, or may have diarrhea or constipation. The patient may have heavy and irregular vaginal bleeding, even after menopause, notes the National Cancer Institute.
The symptoms of primary peritoneal cancer can be due to other diseases as well, reports the Center for Cancer and Blood Disorders. However, if the symptoms worsen and last for several weeks, the patient should go to a doctor for early diagnosis and treatment.
