Causes & Risk Factors

Several factors can contribute to Ovarian Cancer (Epithelial).

Epithelial ovarian cancer develops when normal cells in the ovaries or fallopian tubes undergo genetic changes that cause them to grow uncontrollably.

Epithelial ovarian cancer develops when normal cells in the ovaries or fallopian tubes undergo genetic changes that cause them to grow uncontrollably. Scientists now believe that many cases actually start in the fallopian tubes, where cells become damaged and eventually spread to the ovaries. The exact trigger for these cellular changes remains unclear, but researchers have identified several factors that increase the likelihood of DNA damage occurring.

Hormone exposure plays a significant role in cancer development.

Hormone exposure plays a significant role in cancer development. Each time a woman ovulates, the surface of the ovary breaks to release an egg, then repairs itself. This repeated process of damage and repair over many years may increase the chance of cellular errors. This explains why factors that reduce lifetime ovulation - like pregnancy, breastfeeding, and birth control pills - tend to lower cancer risk.

Genetic factors contribute substantially to epithelial ovarian cancer risk.

Genetic factors contribute substantially to epithelial ovarian cancer risk. Inherited mutations in genes like BRCA1, BRCA2, Lynch syndrome genes, and others can dramatically increase a woman's lifetime risk. These genetic changes can be passed down through families and affect the body's ability to repair damaged DNA effectively. Environmental factors, age-related cellular changes, and inflammation may also contribute to cancer development, though their exact roles continue to be studied.

Diagnosis

How healthcare professionals diagnose Ovarian Cancer (Epithelial):

1
Diagnosing epithelial ovarian cancer often begins when a woman reports persistent symptoms to her doctor.
Diagnosing epithelial ovarian cancer often begins when a woman reports persistent symptoms to her doctor. Because early symptoms can mimic common digestive issues, doctors typically start with a thorough medical history and physical exam, including a pelvic examination. If ovarian cancer is suspected, the next step usually involves imaging tests and blood work to gather more information about what might be causing the symptoms.
2
The CA-125 blood test measures a protein that's often elevated in women with ovarian cancer, though it can also be high due to other conditions like endometriosis or even menstruation.
The CA-125 blood test measures a protein that's often elevated in women with ovarian cancer, though it can also be high due to other conditions like endometriosis or even menstruation. Imaging studies such as transvaginal ultrasound, CT scans, or MRI help doctors visualize the ovaries and surrounding structures. These tests can reveal masses, fluid accumulation, or other changes that suggest cancer, but they can't definitively diagnose it.
3
The only way to confirm epithelial ovarian cancer is through tissue analysis, either from a biopsy or surgical removal of the suspicious tissue.
The only way to confirm epithelial ovarian cancer is through tissue analysis, either from a biopsy or surgical removal of the suspicious tissue. In many cases, doctors recommend surgery both to diagnose and treat the cancer simultaneously. During this procedure, called staging surgery, the surgeon removes the ovaries, examines the abdomen thoroughly, and takes tissue samples to determine how far the cancer has spread. This information helps determine the cancer's stage and guides treatment decisions.

Complications

The most serious complication of epithelial ovarian cancer is its tendency to spread throughout the abdominal cavity before causing obvious symptoms.
When cancer cells seed the peritoneum (the lining of the abdomen), they can cause fluid buildup called ascites, bowel obstructions, and difficulty eating.
These complications can develop gradually over months or more rapidly if the cancer is aggressive.
Treatment-related complications can also significantly impact quality of life.
Chemotherapy may cause neuropathy (nerve damage) that affects hands and feet, hearing changes, fatigue, and increased infection risk.
Surgery, especially extensive debulking procedures, carries risks of bleeding, infection, and damage to surrounding organs.
Long-term survivors may experience early menopause symptoms, bone density changes, and increased risk of heart disease if treatment included removing the ovaries before natural menopause.

Prevention

While there's no guaranteed way to prevent epithelial ovarian cancer, several strategies can significantly reduce risk.
Birth control pills offer one of the most protective effects - women who use them for five or more years cut their risk by about 50%.
Pregnancy and breastfeeding also provide protection, with risk decreasing with each full-term pregnancy and extended breastfeeding period.
For women with high genetic risk, particularly those with BRCA mutations, preventive surgery offers the most effective protection.
Removing the ovaries and fallopian tubes (called risk-reducing bilateral salpingo-oophorectomy) can reduce ovarian cancer risk by 85-95%.
This surgery is typically recommended after age 35-40 or when childbearing is complete.
Some women may choose to have their fallopian tubes removed while keeping their ovaries until menopause.
Regular medical care and genetic counseling can help identify women at higher risk who might benefit from enhanced screening or preventive measures.
While routine screening isn't recommended for average-risk women, those with strong family histories or genetic mutations may benefit from periodic CA-125 blood tests and transvaginal ultrasounds, though these tests aren't perfect for early detection.

Treatment Approaches

Treatment for epithelial ovarian cancer typically involves a combination of surgery and chemotherapy, with the specific approach depending on the cancer's stage, the patient's overall health, and other individual factors.

Treatment for epithelial ovarian cancer typically involves a combination of surgery and chemotherapy, with the specific approach depending on the cancer's stage, the patient's overall health, and other individual factors. Most women undergo surgery first to remove as much cancer as possible - a procedure called cytoreductive or debulking surgery. This often includes removing both ovaries, the fallopian tubes, the uterus, and any visible cancer deposits throughout the abdomen.

SurgicalOncology

Chemotherapy plays a central role in treating epithelial ovarian cancer.

Chemotherapy plays a central role in treating epithelial ovarian cancer. Most patients receive platinum-based drugs like carboplatin combined with paclitaxel, either after surgery or sometimes before surgery to shrink tumors. The treatment typically involves six cycles given intravenously every three weeks. Some women may receive intraperitoneal chemotherapy, where drugs are delivered directly into the abdominal cavity for more concentrated treatment of cancer cells.

SurgicalMedicationOncology

Targeted therapy has revolutionized treatment for certain types of epithelial ovarian cancer.

Targeted therapy has revolutionized treatment for certain types of epithelial ovarian cancer. PARP inhibitors like olaparib, niraparib, and rucaparib work particularly well in women with BRCA mutations or other DNA repair defects. Bevacizumab, which targets blood vessel growth, may be added to chemotherapy for advanced cases. These medications can significantly extend the time before cancer returns.

For recurrent disease, treatment options include different chemotherapy combinations, clinical trials of new drugs, and sometimes additional surgery.

For recurrent disease, treatment options include different chemotherapy combinations, clinical trials of new drugs, and sometimes additional surgery. Immunotherapy is showing promise in clinical trials, and newer targeted drugs are constantly being developed. The key is working with an experienced gynecologic oncology team that can tailor treatment to each woman's specific situation and adjust the plan as needed based on how the cancer responds.

Living With Ovarian Cancer (Epithelial)

Managing life with epithelial ovarian cancer requires building a strong support network and adapting to both physical and emotional challenges. Many women find that connecting with other survivors through support groups provides invaluable practical advice and emotional support. The Cancer Support Community and organizations like SHARE offer both in-person and online resources specifically for ovarian cancer patients.

Physical recovery varies greatly depending on treatment intensity and individual factors.Physical recovery varies greatly depending on treatment intensity and individual factors. Some women return to normal activities relatively quickly, while others need months to regain strength and energy. Regular exercise, when approved by the medical team, can help combat fatigue and maintain bone health. Nutritional support may be necessary if treatment affects appetite or digestion, and working with an oncology dietitian can be helpful.

Emotional and practical considerations include - Managing treatment schedules and medical appointments - Dealing with insurance and financial concerns - Communicating with family and friends about the diagnosis - Planning for work accommodations or disability if needed - Considering fertility preservation options for younger women - Exploring complementary therapies like meditation or acupuncture for symptom management.Emotional and practical considerations include - Managing treatment schedules and medical appointments - Dealing with insurance and financial concerns - Communicating with family and friends about the diagnosis - Planning for work accommodations or disability if needed - Considering fertility preservation options for younger women - Exploring complementary therapies like meditation or acupuncture for symptom management. Many women find that maintaining some sense of normalcy and continuing meaningful activities, even in modified ways, helps preserve their sense of identity beyond the cancer diagnosis.

Frequently Asked Questions

Can epithelial ovarian cancer be detected with regular Pap smears?

No, Pap smears only screen for cervical cancer and don't detect ovarian cancer. There's currently no reliable screening test for ovarian cancer in average-risk women.

Will I be able to have children after treatment?

Treatment typically involves removing the ovaries, which ends natural fertility. However, younger women may explore fertility preservation options like egg or embryo freezing before treatment begins.

How often will I need follow-up appointments after treatment?

Most women see their oncologist every 3-4 months for the first few years, then less frequently. Follow-up includes physical exams, CA-125 blood tests, and imaging studies as needed.

Should my family members get genetic testing?

If you test positive for a hereditary cancer syndrome like BRCA mutations, your blood relatives may benefit from genetic counseling and testing. Discuss this with a genetic counselor.

Can I take hormone replacement therapy if I'm in treatment?

This depends on your specific situation and treatment plan. Many doctors avoid hormone therapy in ovarian cancer patients, but some women may be candidates under certain circumstances.

What dietary changes should I make during treatment?

Focus on maintaining good nutrition with adequate protein and calories. Some women need to eat smaller, more frequent meals. An oncology dietitian can provide personalized guidance.

Is it safe to travel during chemotherapy?

Travel may be possible between chemotherapy cycles when your blood counts recover, but check with your medical team first. Avoid crowded areas when your immune system is compromised.

Will the cancer definitely come back?

Not necessarily. Some women, especially those diagnosed at early stages, may never have a recurrence. Even with advanced disease, some patients remain cancer-free for many years.

Can I exercise during treatment?

Light to moderate exercise is often beneficial and safe during treatment, but get approval from your medical team first. Start slowly and listen to your body's signals.

How do I know if my symptoms mean the cancer is returning?

Contact your medical team about persistent bloating, abdominal pain, changes in bowel habits, or other symptoms that concern you. Regular monitoring helps catch any recurrence early.
