In most ovarian cancers, surgery does three jobs at once. It confirms the diagnosis, because the tissue is examined under a microscope. It shows exactly how far the disease has spread, which is called staging. And it removes as much of the cancer as can be safely taken out.
That third job is the one that carries the most weight. In advanced ovarian cancer, studies consistently link the amount of tumour left behind after surgery to how well treatment works. The goal of the operation is therefore to remove all visible disease wherever that can be done safely.
Research also suggests that surgery planned and performed by a gynecologic oncologist is associated with better outcomes, which is the reason many guidelines advise referral to one.
There is no single “ovarian cancer operation”. What you need depends on the stage, the type of tumour, your age, your general health and whether you hope to have children.
When scans suggest the cancer is confined to the ovary, the operation usually removes the ovaries and fallopian tubes and the uterus, and also takes samples from the omentum (a fatty apron in the abdomen), the lining of the abdomen and sometimes lymph nodes. Fluid from the abdomen is also tested. These samples matter because a number of cancers that look early on a scan turn out to be more advanced once tissue is examined. Some are found to be at a higher stage, and that changes the treatment you are offered.
For selected young women with a small, early-stage and lower-grade tumour, it may be possible to take out only the affected ovary and tube and leave the uterus and the other ovary in place, after careful staging. This is not an option for everyone. It depends on the exact type and grade of the tumour. Women who go this route are usually advised about removing the remaining organs once their family is complete, and need regular follow-up. If this matters to you, say so at the first visit.
When the cancer has spread through the abdomen, the aim is to remove every visible deposit in one operation, followed by chemotherapy. Depending on where the disease sits, this can include removing the uterus, both ovaries and tubes, the omentum, and affected areas of the peritoneum. Sometimes part of the bowel, the diaphragm lining, or enlarged lymph nodes also need to be dealt with. Read more on our page about cytoreductive surgery.
Not every patient is fit for a big operation at diagnosis, and in some the disease is too widespread to remove completely at the first attempt. In these cases, doctors may give a few cycles of chemotherapy first, then operate. This is called interval surgery. Your scans and your response to chemotherapy decide the timing.
If the cancer returns after a long gap, a repeat operation can be considered for carefully selected patients. It is a separate discussion that depends on where the cancer has recurred and how you are doing.
A good operation starts with good planning. Before surgery you can expect:
A detailed history and clinical examination.
Imaging, usually a CT scan, sometimes an MRI or PET-CT, to see how far the disease has spread.
Blood tests, including tumour markers such as CA-125, along with tests of your fitness for anaesthesia.
A review of any biopsy or pathology report.
A discussion about genetic testing, since BRCA and related gene changes affect treatment choices and may matter for your daughters, sisters and other relatives.
A conversation about fertility, menopause and your goals.
Important Note: Tell the team about every medicine you take and any earlier surgeries. If there are heart, lung, diabetes or blood-pressure issues, these are sorted out before the operation, not on the day.
Many women ask whether the operation can be done through small cuts. For some early-stage cases, a minimal access approach can be a reasonable option, with benefits like less pain and a quicker recovery. One precaution is that a suspected cancerous ovary must be removed without bursting it, usually inside a protective bag.
For advanced disease, an open operation through a longer abdominal incision is often needed because the surgeon has to see and reach the entire abdomen. Neither route is automatically “better”. The right one is the one that clears the cancer safely in your case. Dr. Swasti’s training covers laparoscopic and robotic surgery as well as open procedures, so the recommendation is based on your disease, not on what is available. You can read about each on our pages for laparoscopic, robotic and open gynecologic cancer surgery.
Every major operation carries risk, and honest conversations include them. For ovarian cancer surgery these can include:
Bleeding, which may need a blood transfusion.
Infection of the wound, the chest or the urinary tract.
Blood clots in the legs or lungs, which is why walking early and blood-thinning injections are part of the plan.
Injury to nearby organs such as the bowel, bladder or ureters.
Leg swelling if lymph nodes are removed.
Sudden menopause if both ovaries are removed before natural menopause.
A temporary or, less often, permanent stoma (a bag on the abdomen to collect stool) if a section of bowel has to be removed. This is not common for every patient, and your surgeon will tell you before surgery if it is a real possibility.
Surgery in advanced ovarian cancer is major and recovery takes time, but for many women it is the step that makes the rest of treatment work.
How long you stay in hospital depends on the extent of the operation. After a limited procedure you may go home within a few days. After extensive debulking surgery the stay is longer, and some patients need monitoring in intensive care for a short period at first.
You will be encouraged to sit up and walk soon after surgery. This lowers the risk of clots and chest infection.
Diet returns in stages, depending on whether the bowel was handled.
Expect to tire easily for several weeks. Avoid lifting heavy weights until your surgeon clears you.
If chemotherapy is planned, it usually starts once you have healed well enough, and your team will tell you when.
Regular check-ups, blood tests such as CA-125 and scans are used to keep watch after treatment.
When to Call Your Doctor: Call your doctor early if you have fever, a wound that is red or leaking, worsening pain, vomiting, leg swelling or breathlessness.
For most women, treatment combines surgery with chemotherapy, and in some cases targeted therapy chosen based on tumour and gene testing. In selected patients with advanced disease, HIPEC may be considered together with cytoreductive surgery. Dr. Swasti coordinates the surgical side of care and works with medical oncology colleagues for chemotherapy so that you are not left to join the dots yourself. Cancer of the fallopian tube is treated along very similar lines, and you can read about it on our fallopian tube cancer page.
It helps to go to the appointment with a short list. You can ask:
What stage do you think this is, and how sure are you before the operation?
What exactly will be removed, and what is the chance I will need more than we planned?
Could I need a stoma or part of the bowel removed?
Is fertility preservation possible in my case?
Will I need chemotherapy before or after surgery?
Should I have genetic testing, and what does it mean for my family?
How long will I be in hospital, and what will recovery look like at home?
