Ovarian, fallopian tube, and peritoneal cancers are closely related conditions that typically begin in the female reproductive organs.
Your ovaries, two almond-sized organs located on each side of your uterus, produce eggs and hormones. Fallopian tubes are small ducts connecting your ovaries to your uterus. The peritoneum is the thin tissue lining your abdomen, covering organs like your uterus, bladder, rectum, and ovaries.
These cancers start when normal cells change and grow uncontrollably, creating a mass called a tumor. The tumors can be cancerous (malignant) or non-cancerous (benign). Although they start in different places, ovarian, fallopian tube, and peritoneal cancers are usually treated the same way.

Most ovarian, fallopian tube, and peritoneal cancers begin at the outer end of the fallopian tube and then spread to the ovary.
Around 85–90% of these cancers are epithelial (epithelial carcinoma), which starts in cells lining your organs.
Epithelial cancers are usually serous (high-grade or low-grade), endometrioid, clear cell, mucinous, mixed, or rare Brenner tumors.
Less common types include germ cell cancers, which begin in egg-producing cells and mostly affect adolescent girls and young women.
Another uncommon type is sex cord-stromal tumors, arising from supportive ovarian cells (granulosa or theca cells).
Symptoms of ovarian, fallopian tube, and peritoneal cancer are often vague at first, but noticing changes can lead to earlier diagnosis.
You might experience:
These symptoms can mimic common health issues, but pay attention if they're persistent or worsen over time.
Finding these cancers early is challenging because there isn't a reliable screening test for women at average risk. If you have symptoms, your doctor might use several tests to identify the issue clearly:
Ovarian, fallopian tube, and peritoneal cancers are usually treated with similar methods. Your doctor will recommend treatments based on your cancer's type, stage, and grade.
Common treatments include:
Your treatment will likely involve multiple specialists working together for your best possible care.

Ovarian cancer typically reaches stage III when it spreads beyond the pelvis to the peritoneum. Stage IIIC specifically refers to cancer deposits larger than 2 cm in the peritoneum or abdomen.
If not detected early, ovarian cancer usually spreads first to nearby pelvic structures, such as the fallopian tubes, uterus, and the peritoneum (abdominal lining). Later, it can reach abdominal organs, lymph nodes, and eventually organs like the liver.
The exact cause of peritoneal cancer isn't fully known, but it usually starts when healthy peritoneal cells develop mutations and grow uncontrollably. Peritoneal cancer can either occur on its own (primary peritoneal cancer) or develop when other cancers, like ovarian cancer, spread into the peritoneum
