Being told there is something on your ovary while you are pregnant is a frightening sentence to hear, so start with where the odds actually sit: most masses found on a pregnancy scan are benign, and ovarian cancer during pregnancy is rare. Where it does turn out to be cancer, the pregnancy usually continues. Surgery and, if it is needed, chemotherapy can both be given at the right point in the pregnancy rather than instead of it.
Two things are true at the same time. Masses on the ovary are a common finding on early pregnancy scans. Ovarian cancer during pregnancy is rare. Holding both in mind is the difference between a worrying few weeks and a frightening one.
Early pregnancy is scanned more closely than almost any other period in a woman's life, which is exactly why an ovarian mass in pregnancy is so often found by accident. In most cases the scan is describing a corpus luteum cyst — the structure left behind after ovulation that produces the hormones supporting the pregnancy until the placenta takes over. It is meant to be there, and it usually shrinks away by the middle of the second trimester. Our guide to ovarian cysts in pregnancy covers that far commoner situation in detail.
Of the masses that are still there after the first trimester, most are still benign: dermoid cysts, endometriomas, and simple serous or mucinous cysts. Only a small minority prove malignant. Put plainly, being diagnosed with ovarian cancer during pregnancy is uncommon enough that most obstetricians will see it rarely across a career — which is precisely why the case should be discussed by people who see ovarian cancer often.
There is one difference from the same diagnosis outside pregnancy, and it runs in your favour. Because these cancers are found by a scan rather than by symptoms, they tend to be caught while still confined to one ovary. The mix of tumour types is different too: borderline tumours and germ cell tumours account for a much larger share in pregnant women than in women in their sixties, and both of those behave very differently from advanced epithelial ovarian cancer. A diagnosis in pregnancy is not the worst version of this disease, even though it arrives at the worst possible moment.
Most ovarian masses in pregnancy are picked up on a routine scan, not because something felt wrong. Being found early rather than late is the single biggest reason the outlook here is usually better than the diagnosis sounds.
A corpus luteum cyst is a normal part of early pregnancy and typically disappears by around 16 weeks. A repeat scan after the first trimester answers most of these cases without any intervention at all.
Borderline and germ cell tumours make up far more of the ovarian cancers found in pregnancy than they do in older women. Both are usually confined to one ovary and both respond well to treatment.
Ovarian cancer is one of the cancers more often diagnosed during pregnancy — and it is still genuinely uncommon: published series place it at somewhere between one in 12,000 and one in 50,000 pregnancies. Adnexal masses, by contrast, are found on a meaningful minority of early scans, and the great majority either resolve or prove benign. Where a malignancy is found in pregnancy, the pattern differs from ovarian cancer outside it: a much larger share are borderline tumours and germ cell tumours, and most are confined to one ovary at diagnosis. That combination is why international guidance treats pregnancy as a reason to time treatment carefully, not as a reason to abandon it.

Almost every test used to characterise an ovarian mass either behaves differently in pregnancy or is set aside altogether. Knowing which is which explains why your team may appear to be doing less than you expected — and why that is usually the right call.
Pelvic ultrasound remains the workhorse. It uses no radiation, it is used at every stage of pregnancy, and it describes the features that matter most: size, whether the mass is simple fluid or has solid areas, whether there are internal walls or nodules, how much blood flow runs through it, and whether there is free fluid in the abdomen.
The most useful thing ultrasound does in pregnancy is repeat itself. A scan at, say, 16 weeks compared against the dating scan tells you whether a mass is resolving, static or growing — and that comparison settles the majority of cases without any further test being needed.
Where the ultrasound appearance is indeterminate, MRI is the next step. It involves no ionising radiation and characterises fat, blood products and solid tissue within a mass better than ultrasound can, which is often enough to identify a dermoid or an endometrioma confidently and to flag the features that raise concern.
One deliberate limitation: gadolinium contrast crosses the placenta and is avoided during pregnancy, so the scan is performed without it. Your radiologist will know this and will report accordingly. If anyone offers you a contrast-enhanced scan, say plainly that you are pregnant and ask them to confirm the plan.
Both use ionising radiation, and PET-CT additionally involves an injected radioactive tracer. Neither is used for routine assessment of an ovarian mass in pregnancy. Where staging information is genuinely needed before delivery, it is obtained from MRI and ultrasound instead, and the remaining staging is completed afterwards.
At CION, PET-CT is coordinated at specialist partner imaging centres rather than performed in-house, so if it is ever discussed for you it will be for after delivery, and it will be arranged rather than assumed.
Pregnancy interferes with nearly every marker used in ovarian cancer. CA-125 rises physiologically in the first trimester and again around delivery. AFP is produced by the fetus and climbs steadily through the pregnancy. hCG is the pregnancy hormone itself. LDH and inhibin also shift. Each of these markers can also be raised by a germ cell or sex-cord tumour, which is exactly the ambiguity that makes them unhelpful here.
The practical consequence is that a raised marker in pregnancy usually tells you nothing, and a normal one does not reassure. Imaging carries the weight, and markers are used mainly to establish a baseline that can be followed after delivery. If a raised CA-125 has already frightened you, that number by itself is not evidence of anything.
Ovarian masses are generally not biopsied through the abdominal wall, in pregnancy or outside it, because puncturing a malignant cyst can spill cells into the abdominal cavity and worsen the stage. The standard route to a diagnosis is surgical removal of the affected ovary and tube, with the pathologist examining the specimen afterwards — sometimes on a frozen section during the operation itself, so that the surgeon can decide how much further to go.
That is why the surgical decision and the diagnostic decision are the same decision here, and why it belongs with a gynaecologic-oncology surgeon rather than a general one. At CION this surgery is coordinated with specialist gynaecologic-oncology surgeons at partner centres, working with your obstetric team.
None of these means cancer. Each is a reason to be seen the same day rather than at your next appointment, because a mass can twist or rupture at any point in a pregnancy — and because pregnancy makes it far too easy to explain symptoms away.
Especially with nausea and vomiting, and especially if it came on abruptly. This is the pattern of ovarian torsion, which is a surgical emergency at any stage of pregnancy.
Fever alongside pelvic pain, or lightheadedness and a racing heart, need assessment immediately rather than a wait-and-see. Go to your obstetric unit, not to a routine appointment.
An abdomen enlarging faster than the pregnancy explains, or breathlessness when lying flat, warrants a scan rather than reassurance about the pregnancy alone.
Pregnancy causes plenty of aches. Pain that is severe, constant and unresponsive to simple analgesia is a different thing and should be looked at the same day.
Vaginal bleeding or tightenings occurring alongside pelvic pain need urgent obstetric assessment in their own right, whatever is known about a mass.
Not an emergency, but not something to leave until a routine interval either. Growth across scans is the finding that most often prompts an oncology opinion.
For anything acute, ring your obstetric unit first — they can see and scan you immediately, and torsion is time-critical. If the question that follows is whether the mass could be cancer, that is when an oncology opinion earns its place, and you can book one free at CION without a referral.
A 45-minute consultation, your scan images reviewed properly, and a plain answer about whether this needs surgery, monitoring, or nothing beyond a repeat scan — worked through with your obstetrician rather than around her.

Nothing here is decided by one doctor. The plan is built by your obstetrician, a gynaecologic-oncology surgeon and a medical oncologist together, because it has to work for two patients rather than one.
A repeat ultrasound after the first trimester, MRI without contrast where the appearance is indeterminate, and a specialist reading of both. A great many masses declare themselves benign at this point and the plan becomes ordinary antenatal care with one more scan. Read what happens with a cyst in pregnancy for how that far commoner path runs.
Where the imaging raises a genuine question, the case goes to a tumour board with obstetrics involved. Three questions get answered together: how confident is the diagnosis, how many weeks pregnant are you, and does treatment need to start now or can it wait until after delivery. Gestation changes the answer more than almost anything else.
When surgery is needed, the window generally chosen is the early second trimester. Operating in the first trimester carries a higher chance of miscarriage; leaving it much later makes access difficult as the uterus grows. The usual operation removes the affected ovary and tube, with staging where warranted and completion after delivery if needed. All of this is coordinated with specialist gynaecologic-oncology surgeons at partner centres and may be billed there — CION arranges it and stays in the decision rather than performing it.
Chemotherapy is not given in the first trimester, when the baby's organs are forming. From the second trimester onward, platinum-based chemotherapy has the largest published experience in pregnancy and is what is generally used. It carries real risks — most commonly restricted fetal growth and preterm birth — which are weighed against the risk of leaving a cancer untreated for months. This part of your treatment is delivered in-house at CION.
Chemotherapy is usually stopped around three weeks before the expected delivery, so that your blood counts and the baby's have recovered before birth. The obstetric team aims for term or as close to it as the situation allows, because prematurity carries its own harms and is not a neutral trade. The mode of delivery is an obstetric decision, and the placenta is sent for examination afterwards.
What was deferred is completed once you have delivered: any remaining staging surgery, the rest of the chemotherapy, and maintenance therapy, which is not given during pregnancy at all. Genetic counselling with BRCA and HRD testing is arranged in-house at CION, since a result changes your own follow-up as well as what your family may want to know. Breastfeeding is not recommended while chemotherapy is being given, and your team will tell you when that changes.
Future fertility belongs in this conversation from the start, not afterwards — see ovarian cancer and fertility for what different operations leave you with. For how the whole pathway is sequenced outside pregnancy, see ovarian cancer treatment in Hyderabad, and the complete ovarian cancer guide for the wider picture.
The hardest part of this situation is usually not the medicine — it is being handed a frightening possibility at an antenatal appointment with ten minutes to absorb it. A second opinion from someone who sees ovarian disease every week is worth having early, whether the answer turns out to be reassuring or not. Your first consultation at CION is free and runs to about 45 minutes, which is long enough to go through the scan images and the report properly rather than talk in generalities.
Every case that raises a question is discussed at a tumour board rather than settled by one doctor, and where you are pregnant that discussion includes your obstetrician. We do not order tests you do not need, and we will not repeat imaging that has already answered the question. Where the honest answer is that this looks like a corpus luteum cyst and needs one repeat scan, that is what we will say.
Two things we do not do in-house, and would rather say plainly now than have you discover later. All ovarian surgery — including surgery during a pregnancy — is delivered by specialist gynaecologic-oncology surgeons at partner centres and may be billed there; CION coordinates it and remains part of the decision. PET-CT is likewise coordinated at partner imaging centres, and is avoided during pregnancy in any case. What CION delivers itself is medical oncology: chemotherapy and maintenance therapy across 35+ centres in Telangana and Andhra Pradesh, along with genetic counselling, BRCA and HRD testing, nutrition support and long-term follow-up.
Free, unhurried and with a specialist. Bring your scan images and reports — most of this question is answered by reading them carefully with you.
Cases in pregnancy are reviewed by medical oncology, imaging and pathology together with your obstetric team, because the plan has to work for the pregnancy as well as the cancer.
Ovarian surgery with specialist gynaecologic-oncology partner centres, and PET-CT with partner imaging centres. Coordinated by us, delivered and billed there.
Chemotherapy and follow-up delivered close to where you live across Telangana and Andhra Pradesh — which matters a great deal when you are also attending antenatal appointments.
The cancer itself almost never reaches the baby. Spread of a maternal cancer to the fetus is exceptionally rare, and the placenta is examined after delivery precisely because that possibility, though remote, is checked rather than assumed. What does affect the baby is the treatment and its timing. Surgery in the first trimester carries a higher chance of miscarriage, which is why it is usually scheduled for the second. Chemotherapy is avoided while the organs are forming in the first trimester, and given from the second trimester onward it is associated with restricted growth and preterm birth rather than with birth defects. Those risks are real and are weighed openly against the risk of leaving a cancer untreated for several months. Your baby's growth is monitored with obstetric ultrasound throughout.
For most women, no. International guidance is explicit that a cancer diagnosis in pregnancy is not in itself a reason to terminate, and that treatment can usually be given while the pregnancy continues. Most ovarian cancers found in pregnancy are confined to one ovary, and removing that ovary and tube in the second trimester leaves the pregnancy intact. The situations where ending the pregnancy is genuinely discussed are uncommon: very advanced disease found very early in the pregnancy, where treatment cannot wait and cannot safely be given. Even then it is a discussion, with you at the centre of it, rather than an instruction. Ask your team directly what they think and why — and if the answer feels rushed, that is a reasonable moment to seek a second opinion.
Where surgery is needed, the early second trimester is the window usually chosen. Operating in the first trimester carries a higher risk of miscarriage, and waiting much beyond the middle of the pregnancy makes the operation technically harder as the uterus grows. Surgery at any stage carries some risk to the pregnancy, and that risk is low enough in the second trimester that it is generally accepted when there is a real suspicion of cancer. The usual operation removes the affected ovary and tube; the other ovary and the uterus are left alone wherever the disease allows. Some masses that look benign are simply watched with repeat scans instead, and no operation happens at all. At CION this surgery is coordinated with specialist gynaecologic-oncology surgeons at partner centres.
It is used in pregnancy, deliberately and under close monitoring, but it is not without consequence and nobody should tell you otherwise. Chemotherapy is not given in the first trimester, when organs are forming. From the second trimester onward, platinum-based chemotherapy has the largest body of published experience in pregnancy and is generally what is used for ovarian cancer. The effects most often reported are restricted fetal growth and preterm birth rather than structural abnormalities. Treatment is usually stopped about three weeks before the expected delivery so that both your blood counts and the baby's recover before birth. Maintenance therapy is not given during pregnancy and is started afterwards. Breastfeeding is not recommended while chemotherapy is being given.
CT and PET-CT both use ionising radiation, and PET-CT also involves an injected radioactive tracer, so neither is used to assess an ovarian mass in pregnancy. MRI does not use radiation and is used in pregnancy when ultrasound cannot settle what a mass is. The one modification is that gadolinium contrast crosses the placenta and is avoided, so the MRI is done without it. This is also why tumour markers are of limited help here: CA-125 rises normally in the first trimester and around delivery, and AFP, hCG, LDH and inhibin all shift during pregnancy. Imaging carries the weight, staging is completed after delivery where necessary, and a raised marker on its own is not evidence of cancer.
The first consultation is free and runs to about 45 minutes. CION delivers medical oncology for ovarian cancer in-house — chemotherapy and maintenance treatment across more than 35 centres in Telangana and Andhra Pradesh — along with genetic counselling, BRCA and HRD testing, nutrition support and long-term follow-up. Ovarian surgery, including surgery during a pregnancy, is coordinated with specialist gynaecologic-oncology surgeons at partner centres and may be billed there, and PET-CT is likewise coordinated at partner imaging centres. We say so upfront rather than leave it to be discovered later. Every case that raises a question is reviewed at a tumour board, and where you are pregnant your obstetrician is part of that conversation.
