Endometrial cancer

The uterus (womb) is the hollow, pear-shaped organ where a baby grows during pregnancy. Its inner layer is called the endometrium. Each month during the reproductive years, the endometrium thickens to prepare for a possible pregnancy and then sheds during a menstrual period. Endometrial cancer is cancer that starts when cells in this lining begin to grow in an abnormal, uncontrolled way and form a tumour.

Endometrial cancer is the most common type of cancer of the uterus. Doctors sometimes use the broader term uterine cancer, which covers cancers of the whole womb. Most uterine cancers are endometrial cancers. A much rarer form, called uterine sarcoma, begins in the muscle wall of the womb rather than the lining and behaves differently; this guide focuses on endometrial cancer.

The reassuring point worth holding onto is that endometrial cancer usually causes a noticeable symptom, unexpected vaginal bleeding, fairly early. That often leads people to seek help while the cancer is still inside the uterus, which is when treatment tends to work best. It mainly affects women who have been through the menopause, but it can occur at any age in anyone who has a uterus.

When a tissue sample is examined under a microscope, the pathologist (a doctor who studies cells and tissues) identifies which kind of endometrial cancer it is. The type matters because it helps predict how the cancer is likely to behave and guides treatment.

• Endometrioid adenocarcinoma is by far the most common type. It begins in the gland cells of the lining and is often linked to the hormone oestrogen. Many cases are found early and grow relatively slowly.
• Serous carcinoma is less common and tends to be more aggressive, meaning it can grow and spread more quickly.
• Clear cell carcinoma is a rarer type that can also behave more aggressively.
• Carcinosarcoma makes up roughly 3 percent of cases and contains a mix of cancer cell types.

Doctors also describe cancers in two other helpful ways. The grade (1 to 3) describes how abnormal the cells look: grades 1 and 2 are lower-grade and usually slower-growing, while grade 3 is higher-grade and tends to grow faster. An older framework divides tumours into Type 1 (oestrogen-related, generally less aggressive) and Type 2 (not oestrogen-driven, generally more aggressive). More recently, laboratories may also test the tumour's molecular profile (for example, changes in genes such as POLE or p53, or a feature called mismatch-repair deficiency), which can refine the picture of risk and open up specific treatment options.

No one can say exactly why one person develops endometrial cancer and another does not. What researchers have identified are risk factors, things that make it statistically more likely. Having one or several does not mean you will get the cancer, and many people with risk factors never do. Equally, the cancer can occur in people with no obvious risk factors.

Most known risk factors relate to long-term exposure of the endometrium to the hormone oestrogen without the balancing effect of another hormone, progesterone. Recognised factors include:

• Being past the menopause and older age in general
• Carrying extra body weight (obesity), and conditions linked to it such as type 2 diabetes
• Taking oestrogen-only hormone replacement therapy (HRT) without progesterone
• Taking tamoxifen, a medicine used to treat or prevent breast cancer
• Starting periods early or reaching the menopause late
• Never having been pregnant
• Polycystic ovary syndrome (PCOS)
• A family history of endometrial or bowel cancer, including an inherited condition called Lynch syndrome

If endometrial or bowel cancer runs in your family, it is worth mentioning this to your doctor, who can advise whether genetic counselling or extra monitoring would be sensible.

The most important and most common symptom is abnormal vaginal bleeding. This is the warning sign that leads most people to seek help. It may take different forms:

• Any vaginal bleeding after the menopause (this should always be checked, even a single spot)
• Bleeding between periods, or unusually heavy or irregular periods, in those who have not yet been through the menopause
• A watery, blood-tinged or unusual vaginal discharge

Less common symptoms can include pelvic pain or pressure, pain during sex, or, in more advanced cases, unintended weight loss.

Here is the calm and honest perspective: most vaginal bleeding, especially after the menopause, turns out not to be cancer. It is often caused by harmless conditions. But because bleeding is also the main early sign of endometrial cancer, it is always worth getting checked promptly. Seeing a doctor early does not mean something is seriously wrong; it simply gives you answers and, if anything needs treating, the best possible head start. Arrange an appointment with a doctor or gynaecologist if you notice bleeding after the menopause or any persistent change in your bleeding pattern.

It helps to clear up a common confusion: there is no routine screening test for endometrial cancer for women at ordinary risk, and the cervical smear test (Pap test) is not designed to detect it. The smear test checks the cervix for a different cancer and cannot reliably find cancer of the womb lining.

Because there is no screening programme, early detection depends almost entirely on noticing symptoms and acting on them. This is actually good news in one sense: the cancer's main symptom, unexpected bleeding, tends to appear at an early, treatable stage, so paying attention to your own body is the single most powerful tool you have.

People at higher risk are treated differently. For example, those with Lynch syndrome may be offered regular check-ups, which can include an annual endometrial biopsy (a small tissue sample), sometimes starting around the age of 35. If you have a strong family history of womb or bowel cancer, ask your doctor whether any extra monitoring is right for you.

If you report abnormal bleeding, the doctor will ask about your symptoms and medical and family history and usually perform a pelvic examination. Several straightforward tests are then used to look at the womb lining:

• Transvaginal ultrasound: a smooth, slim probe is gently placed in the vagina to produce pictures of the uterus and measure the thickness of the lining.
• Endometrial biopsy: a very thin tube is passed through the cervix to collect a small sample of the lining. This is often done in the clinic and is the key test for confirming or ruling out cancer.
• Hysteroscopy: a thin telescope with a camera is passed into the uterus so the doctor can look directly at the lining and take targeted samples.
• Dilation and curettage (D&C): a short procedure, usually under anaesthetic, to remove and examine a larger tissue sample if needed.

If cancer is confirmed, further tests such as an MRI or CT scan help determine the stage, that is, how far the cancer has spread. Staging usually runs from Stage I (confined to the uterus) through Stage II (reaching the cervix), Stage III (spread within the pelvis, for example to nearby tissues or lymph nodes), to Stage IV (spread to the bladder, bowel or more distant organs). Staging is not a judgement about you; it is simply a map that helps the medical team choose the most suitable treatment.

Treatment is planned by a multidisciplinary team, a group of specialists who meet to agree the best approach for each person. This typically includes a gynaecological oncologist (a surgeon specialising in cancers of the female reproductive organs), a medical oncologist, a radiation oncologist, a pathologist, radiologists and specialist nurses. The plan depends on the type, grade, stage and molecular features of the cancer, and on your overall health and wishes.

Surgery is the main treatment for most endometrial cancers. The usual operation is a hysterectomy (removal of the uterus), most often together with removal of the cervix, the fallopian tubes and the ovaries (a bilateral salpingo-oophorectomy). The surgeon may also check nearby lymph nodes, increasingly using a technique called sentinel lymph node mapping, which samples the first few nodes the cancer would be likely to reach. Many of these operations can be performed using keyhole (laparoscopic) or robot-assisted methods, which can mean smaller incisions and a quicker recovery.

Depending on the findings, additional treatments may be advised to lower the chance of the cancer returning or to treat more advanced disease:

• Radiotherapy (radiation therapy) uses targeted energy beams, or a source placed inside the vagina (brachytherapy), to destroy any remaining cancer cells.
• Chemotherapy uses medicines that travel through the body to attack cancer cells, often for higher-risk or more advanced cancers.
• Hormone therapy may help cancers that are sensitive to hormones, and is sometimes considered for younger people who wish to preserve fertility, in carefully selected cases.
• Targeted therapy and immunotherapy are newer treatments that act on specific features of the cancer or help the immune system fight it; eligibility often depends on the tumour's molecular profile.

Supportive (palliative) care, which focuses on comfort, symptom relief and emotional wellbeing, can run alongside any of these treatments at any stage and is a normal, valuable part of good cancer care.

The outlook for endometrial cancer is, for many people, encouraging, largely because it is often found early. The single biggest factor influencing outlook is the stage at which the cancer is diagnosed; the type, grade and a person's general health also play a part.

To give a sense of scale, here are population-level figures from cancer authorities. Cancer Research UK reports five-year survival for womb cancer in England of more than 90 percent for Stage 1, around 75 percent for Stage 2, around 50 percent for Stage 3 and around 15 percent for Stage 4. Using a different system, the American Cancer Society reports five-year relative survival of about 96 percent when the cancer is localised (confined to the uterus), about 72 percent when it has spread to nearby structures, and about 22 percent when it has spread to distant organs, with about 84 percent across all stages combined.

Please read these numbers gently and in context. They describe large groups of people diagnosed years ago, not any one individual, and they cannot predict what will happen for you. Because treatments keep improving, people diagnosed today may do better than older statistics suggest. The only person who can interpret what these figures mean in your specific situation is the specialist who knows your case.

Life after a diagnosis of endometrial cancer involves both physical recovery and emotional adjustment, and support is available for both. After treatment, you will usually have regular follow-up appointments. These typically involve a conversation about how you are feeling, a physical and pelvic examination, and a check for any returning symptoms; scans or other tests are arranged if needed. The schedule is more frequent at first and gradually spaces out over the years if all remains well.

Surgery to remove the uterus and ovaries means periods stop and pregnancy is no longer possible; if the ovaries are removed before natural menopause, it brings on the menopause, and your team can discuss managing any symptoms. Many people find it helps to know what changes to expect in advance.

Everyday wellbeing matters too. A balanced diet, gentle activity that builds up over time, good sleep and managing other health conditions such as diabetes all support recovery. It is completely normal to feel anxious, low or simply tired during this period. Talking to your specialist nurse, your doctor, a counsellor, or a cancer support organisation can make a real difference. You do not have to manage any of it alone.

If you are considering treatment in another country, it helps to understand what shapes the overall cost so you can plan realistically. We do not list prices here because every case is genuinely different, and an honest estimate can only be given once your medical details are reviewed. The main factors include:

• The type and stage of the cancer, which determine how extensive treatment needs to be
• The type of surgery (for example, open, keyhole or robot-assisted) and the length of hospital stay
• Whether additional treatments such as radiotherapy, chemotherapy, hormone therapy or immunotherapy are needed, and for how long
• Laboratory and molecular testing of the tumour
• Scans, anaesthesia, medicines and follow-up appointments
• Practical costs such as travel, accommodation and translation or interpreting support

To get a clear, personalised picture, it helps to gather your records before reaching out: any biopsy or pathology reports, scan images and reports (ultrasound, MRI, CT), a summary of your diagnosis and stage, a list of your current medicines, and relevant medical history. With these in hand, a specialist team can review your case and give you a tailored plan and estimate. A free consultation is the simplest way to understand your options and what they would involve, with no obligation.

Turkiye has become a well-established destination for medical care, including cancer treatment, drawing patients from across Europe, the Gulf and beyond. It offers modern hospitals, experienced specialist teams and comparatively short waiting times, often combined with coordinated support for international patients such as interpreters and help with travel logistics. The aim of arranging care here is to give you access to a capable, multidisciplinary team without long delays.

Rather than relying on claims of being the biggest or best, focus on objective things you can verify. Sensible questions to ask of any centre, in Turkiye or elsewhere, include:

• Is the hospital accredited by a recognised body such as Joint Commission International (JCI)? Turkiye has many JCI-accredited hospitals.
• Does it have a dedicated gynaecological oncology service and a true multidisciplinary team, including surgical, medical and radiation oncology and pathology?
• What are the qualifications and experience of the surgeon who would treat you, and how often do they perform this type of operation?
• Is molecular and pathology testing available on site so treatment can be tailored?
• How will your follow-up and communication with your doctors at home be handled after you return?

A trustworthy team will welcome these questions, give clear written information, and never pressure you. Getting a second opinion, whether at home or abroad, is always a reasonable step.

While endometrial cancer cannot be reliably prevented, some everyday choices may lower the risk. Maintaining a healthy body weight, staying physically active and managing conditions such as type 2 diabetes all help, because they influence the hormone balance linked to the disease. If you are considering hormone replacement therapy, discuss the type and balance of hormones with your doctor. Above all, the most practical step anyone can take is to report unexpected vaginal bleeding promptly rather than waiting.

If you are diagnosed, remember two further options. A second opinion is a normal and accepted part of cancer care; reputable doctors expect and respect it, and it can give you confidence in your plan. And clinical trials, carefully run studies of new or improved treatments, may be available and worth asking your team about, as they can offer access to promising approaches while contributing to better care for others. Whatever you decide, working closely with a qualified specialist who knows your full history is the best foundation for the choices ahead.
