CION Cancer Clinics
Treating early womb cancer while keeping the chance of pregnancy | CION Cancer Clinics
Some younger women with very early, low-grade endometrial cancer can be treated with progestin, a hormone medicine given as tablets or a coil, instead of having the womb removed. The womb lining is sampled every few months to check the response. The cancer can return, so surgery is usually advised once your family is complete. This page explains who may be suited, and who is not. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Can endometrial cancer be treated without removing the womb?
In a small group of younger women with very early, low-grade endometrial cancer, yes. Instead of a hysterectomy, the cancer can be treated with progestin, a hormone medicine, while the womb lining is checked closely, so that a pregnancy remains possible.
What endometrial cancer is
Endometrial cancer starts in the lining of the womb, the endometrium. It is also called womb or uterine cancer. It is more common after menopause, but it does affect younger women, especially those with irregular periods, polycystic ovaries or a higher body weight.
What the standard treatment is
The usual treatment is surgery to remove the womb, the tubes and often the ovaries. For most women this remains the safest choice. It ends the possibility of carrying a pregnancy.
How the hormone approach works
Many early endometrial cancers grow in response to the hormone oestrogen. Progestin works against oestrogen in the lining of the womb and can make these early cancer cells shrink back. It does not work for everyone, and the cancer can return after it has responded. That is why the checks are frequent and why surgery is usually advised once your family is complete.
This is a non-surgical path chosen with your treating team. It is not a decision to make alone.Who it may suit
What has to be true before this is considered?
The conditions are strict. Your team checks each one before suggesting the hormone approach.
The right type and grade
The cancer must be the common endometrioid type and low grade, meaning the cells still look fairly close to normal. Atypical hyperplasia, a condition just before cancer, is treated the same way.
Confined to the lining
An MRI scan must show that the cancer has not grown into the muscle wall of the womb and has not spread beyond it.
Scans can miss very small spread, which is one reason close checks follow.A real wish for pregnancy
The approach carries more uncertainty than surgery. It is offered to women who want to keep the chance of a pregnancy and accept that trade.
Able to keep up follow-up
Regular visits and repeated sampling of the lining are essential.
Also checked
- No health reason to avoid progestin
- The ovaries look normal on the scan
- Family history of bowel or womb cancer
Not sure whether this applies to you?
Ask an oncologistThe pathway
What does the treatment look like, from start to pregnancy?
-
Confirming the diagnosis
A sample of the lining is taken, often by hysteroscopy, a thin camera passed through the cervix. The slides may be reviewed by a second pathologist, because the grade decides everything that follows.
-
Scans and tests
An MRI checks the womb wall and the ovaries. Blood tests and sometimes a test for Lynch syndrome, an inherited condition linked to womb and bowel cancer, may follow.
-
Starting progestin
Treatment is given as tablets, as a hormone coil placed inside the womb, or both. Your gynaecological oncologist chooses the form and the dose. Do not change or stop it on your own.
-
Repeat sampling every few months
The lining is sampled again at regular intervals to see whether the cancer is responding. If it is not responding, surgery is usually advised.
-
Trying for a pregnancy
Once samples show no cancer, the team advises when to try. Many women are referred to a fertility specialist straight away, because time matters.
-
After the family is complete
A hysterectomy is usually recommended, since the cancer can return in the lining.

Commonly believed
What do families often believe about this treatment?
A good response is real, but the cancer comes back in a significant share of women, sometimes years later. That is why sampling continues and why removing the womb is usually advised once pregnancy plans are complete.
It is only safe for a narrow group. For higher-grade cancers, other types or deeper spread, delaying surgery can allow the cancer to grow. Your team will be clear if you are outside that group.
Extra body fat makes more oestrogen, which can feed this cancer. Losing weight is often encouraged alongside treatment, and some teams use metformin, a diabetes medicine, though evidence is still being gathered.
Most irregular bleeding is not cancer. Bleeding that keeps happening between periods or is very heavy should still be checked, especially with polycystic ovaries or a higher body weight.
On your report
What do the words on the report mean?
- Endometrioid adenocarcinoma
- The most common type of endometrial cancer, and the only type usually considered for hormone treatment.
- Grade
- How abnormal the cells look. Low grade, often written as grade one, means they look closest to normal cells.
- Myometrial invasion
- Growth of the cancer into the muscle wall of the womb. Any invasion usually rules out the hormone approach.
- Atypical hyperplasia
- Thickened lining with abnormal cells that can turn into cancer. It is treated in a similar way.
- Complete response
- No cancer or abnormal cells found on the repeat sample.
Being straight with you
Who is it not suited to, and what can this page not tell you?
This approach is not suited to higher-grade cancers, less common types such as serous or clear cell cancer, or cancer that has reached the womb wall or beyond. It is also not used if progestin is unsafe for you, for example after certain blood clots.
The trade you are making
Choosing hormone treatment means accepting more uncertainty for a chance at pregnancy. Some women try it and later need surgery anyway. That is not a failure on your part. It is how this treatment works for some.
What this page cannot tell you
It cannot tell you whether your report puts you in the suitable group, how likely a response is, or your chance of pregnancy. Bring your biopsy report, slides and scans to a gynaecological oncologist and ask them to walk you through each point.
Questions we are asked
Common questions about fertility-sparing treatment in endometrial cancer
Is this a surgery or a medicine treatment?
Mainly a medicine treatment. The cancer is treated with progestin rather than an operation to remove the womb. Small procedures are still involved, such as hysteroscopy to take samples of the lining and sometimes to remove visible areas of cancer. Surgery usually comes later, once pregnancy plans are complete.
How long does it take to know if it is working?
It usually takes several months. The first repeat sample shows whether the lining is changing, and further samples confirm it. If there is no response after a reasonable period, surgery is usually advised. Your team will tell you what they consider enough time.
Will the hormone tablets make me gain weight?
Weight gain is a common side effect of progestin tablets, and it works against the treatment. Tell your team early if it happens. A hormone coil may cause fewer whole-body effects, and a dietitian can help. Do not stop the tablets because of side effects without speaking to your doctor.
Can I get pregnant while on progestin?
Progestin works partly by thinning the womb lining, so pregnancy is not usually attempted during active treatment. Once samples show no cancer, the team will advise stopping and when to start trying. Fertility treatment is often suggested to shorten the time needed.
Why am I being asked about my family's cancers?
Some endometrial cancers are linked to Lynch syndrome, an inherited condition that also raises the risk of bowel and ovarian cancer. Knowing this changes follow-up for you and may matter for your relatives. A genetic test and counselling may be offered.
What if the cancer comes back after a pregnancy?
It can happen, and it is why follow-up continues after the baby is born. Most teams then recommend a hysterectomy. Some women with a new, still early return are offered hormone treatment again, but that is decided case by case.
Will the ovaries be removed later?
Not always. In younger women, the surgeon may keep the ovaries at the time of hysterectomy to avoid an early menopause, if they look healthy and there is no inherited risk. Ask your surgeon to explain their advice for your situation.
Is this treatment covered by Aarogyasri or insurance?
Cancer care is usually covered under schemes such as Aarogyasri, CGHS, ECHS and EHS, and by cashless insurers, but cover for long hormone treatment and repeated procedures can vary. Call the helpline with your card or policy details and we will help you check.
