Primary Peritoneal Cancer
About Primary Peritoneal Cancer
Ovarian epithelial cancer, fallopian tube cancer, and primary peritoneal cancer are diseases in which malignant (cancer) cells form in the tissue covering the ovary or lining the fallopian tube or peritoneum.
The peritoneum is the tissue that lines the abdominal wall and covers organs in the abdomen. Primary peritoneal cancer is cancer that forms in the peritoneum and has not spread there from another part of the body. Cancer sometimes begins in the peritoneum and spreads to the ovary.
Signs and symptoms of ovarian, fallopian tube, or peritoneal cancer include pain or swelling in the abdomen.
Ovarian, fallopian tube, or peritoneal cancer may not cause early signs or symptoms. When signs or symptoms do appear, the cancer is often advanced. Signs and symptoms may include the following:
- Pain, swelling, or a feeling of pressure in the abdomen or pelvis.
- Vaginal bleeding that is heavy or irregular, especially after menopause.
- Vaginal discharge that is clear, white, or colored with blood.
- A lump in the pelvic area.
- Gastrointestinal problems, such as gas, bloating, or constipation.
These signs and symptoms also may be caused by other conditions and not by ovarian, fallopian tube, or peritoneal cancer. If the signs or symptoms get worse or do not go away on their own, check with your doctor so that any problem can be diagnosed and treated as early as possible.
Some ovarian, fallopian tube, and primary peritoneal cancers are caused by inherited gene mutations (changes).
The genes in cells carry the hereditary information that is received from a person’s parents. Hereditary ovarian cancer makes up about 20% of all cases of ovarian cancer. There are three hereditary patterns: ovarian cancer alone, ovarian and breast cancers, and ovarian and colon cancers.
