Key Takeaways
Endometrial cancer develops in the lining of the uterus and is the most common gynecologic cancer in the United States
Abnormal vaginal bleeding, especially after menopause, is the most common early warning sign
Most cases are diagnosed at an early stage, when treatment is often highly effective. Five-year survival exceeds 95% for cancer that remains confined to the uterus, but outcomes vary by stage, cancer type, and other factors.
Hormone imbalances, particularly excess estrogen, play a major role in development
Treatment typically involves surgery, with additional therapies based on cancer stage and type
Overview
Endometrial cancer forms in the endometrium, the inner lining of the uterus. This type of cancer accounts for about 90% of all uterine cancers. It primarily affects women after menopause, with most diagnoses occurring between ages 60 and 70.
Tens of thousands of uterine cancers are diagnosed in the United States each year, and most begin in the endometrium. The good news is that most cases are caught early because abnormal bleeding prompts women to see their doctors. When detected early, endometrial cancer has excellent survival rates and responds well to treatment.
Understanding the signs and risk factors helps women recognize when to seek medical care. Early detection and proper treatment make a significant difference in outcomes for this condition. The uterus is a hollow organ about the size of a pear where babies grow during pregnancy. The endometrium is the soft tissue that lines the inside of the uterus. When cancer starts here, it often causes abnormal bleeding. Doctors may use ultrasound and a sample of endometrial tissue to determine the cause.
Symptoms & Signs
Endometrial cancer often causes noticeable symptoms early in its development. The most important sign is abnormal vaginal bleeding, which occurs in about 90% of cases. Paying attention to changes in your body helps catch this cancer when treatment works best.
Primary Symptoms
Abnormal vaginal bleeding - Heavy periods, bleeding between periods, or any bleeding after menopause
Unusual vaginal discharge - Watery, blood-tinged, or foul-smelling discharge that isn't normal for you
Pelvic pain or pressure - Persistent discomfort in the lower abdomen or pelvis area
Pain during urination - Burning, stinging, or difficulty with urination
When to Seek Care
Contact your healthcare provider immediately if you experience any vaginal bleeding after menopause. Also seek care for unusually heavy or prolonged periods, bleeding between periods, or pelvic pain that doesn't improve with time. Don't assume bleeding is normal even if it seems minor.
Any change from your normal pattern deserves a doctor's attention. Women often wait too long to report bleeding, thinking it's normal. Getting checked early gives you the best chance for successful treatment.
When to Seek Immediate Care
See a doctor promptly for any postmenopausal bleeding or significant changes in your menstrual pattern. Early evaluation leads to better outcomes.
Causes & Risk Factors
Endometrial cancer develops when cells in the uterine lining grow uncontrollably. Prolonged estrogen exposure without enough progesterone can contribute to many endometrial cancers, but other biological and genetic pathways also cause the disease. Estrogen is a natural hormone that controls female reproductive functions.
Age
Risk increases significantly after menopause, with most cases occurring after age 50
Genetics
Lynch syndrome can substantially increase lifetime endometrial cancer risk, although the level of risk varies by the gene involved. Some other inherited conditions may also increase risk.
Lifestyle
Obesity and type 2 diabetes are associated with a higher risk of endometrial cancer. The relationship between diet and risk is more complex and may partly reflect its effects on body weight and metabolic health.
Other Conditions
PCOS, endometrial hyperplasia, and never being pregnant increase lifetime estrogen exposure

Diagnosis
Getting an accurate diagnosis involves several steps. Your doctor will review your symptoms, medical history, and perform specific tests to determine if cancer is present.
Medical History & Physical Examination
Your healthcare provider will ask about your bleeding patterns, family history, and previous health conditions. They'll perform a pelvic exam to check for abnormalities in your uterus, ovaries, and surrounding areas. This examination helps identify any masses, enlarged organs, or other concerning signs.
The physical exam also includes checking your abdomen for swelling or fluid buildup. Your doctor may check for enlarged lymph nodes or other signs of spread. Endometrial cancer more commonly spreads first to lymph nodes within the pelvis or abdomen, which cannot usually be assessed by feeling the groin.
Diagnostic Testing
Transvaginal ultrasound - Uses sound waves to create images of your uterus and measure endometrial thickness
Endometrial biopsy - Removes a small tissue sample from the uterine lining for microscopic examination
Hysteroscopy - Inserts a thin, lighted scope through the cervix to visually examine the uterine cavity
D&C (dilation and curettage) - Scrapes tissue from the uterine lining when biopsy results are unclear

Treatment Options
Treatment focuses on removing the cancer while preserving as much normal function as possible. The specific approach depends on the cancer's stage, type, and your overall health. Your doctor will explain all options and help you choose the best plan.
Common Treatments
Total hysterectomy - Surgical removal of the uterus and cervix, which is the standard treatment for most cases
Hormone therapy - Uses progesterone-like medications to slow cancer growth in select early-stage cases
Radiation therapy - High-energy beams target cancer cells, often used after surgery to prevent recurrence
Advanced Treatments
Chemotherapy - Powerful medications destroy cancer cells throughout the body when cancer has spread
Targeted therapy - Newer drugs attack specific proteins that help cancer cells grow and survive
Immunotherapy - Helps your immune system recognize and fight cancer cells more effectively
Most women recover well from surgery within 4-6 weeks. Some side effects from radiation or chemotherapy improve after treatment ends, while others may persist or appear later. Tell your medical team about new or continuing symptoms. Your medical team will manage any discomfort and help you stay as active as possible during recovery.
Just like other serious medical conditions require specialized care, understanding treatment options helps you make informed decisions about your care.
Living with the Condition
Managing endometrial cancer involves adapting to treatment effects while maintaining your quality of life. Most women successfully return to their normal activities after treatment. Life after cancer treatment looks different for everyone, but many women thrive.
Daily Management Strategies
Focus on eating nutritious foods to support healing and energy levels. Stay hydrated and get adequate rest, especially during treatment periods. Keep track of any symptoms or side effects to discuss with your healthcare team. Maintain regular follow-up appointments to monitor your recovery and watch for any signs of recurrence.
Fatigue is common after cancer treatment but usually improves with time. A balanced diet that provides enough protein and calories can support recovery. Ask your care team for nutrition guidance if treatment makes eating difficult. Talking to friends and family about your feelings helps emotional healing too.
Exercise & Movement
Gentle activities like walking, swimming, or yoga can boost energy and improve mood during treatment. Start slowly and gradually increase activity as you feel stronger. Avoid heavy lifting or strenuous exercise until your doctor clears you, especially after surgery. Listen to your body and rest when needed.
Many women join support groups to connect with others who have had endometrial cancer. Sharing experiences and tips with others who understand helps you feel less alone. Your doctor can recommend local or online support resources.
Prevention
Endometrial cancer cannot always be prevented, but maintaining a healthy weight and staying physically active may help lower risk. Many of these strategies also improve your overall health. Small changes now can make a big difference in your future.
Maintain a healthy weight - Obesity increases estrogen levels and doubles your cancer risk compared to normal weight
Stay physically active - Regular activity is associated with a lower risk and can help with weight and metabolic health.
Combination birth control pills are associated with a lower long-term risk, but they are not safe or appropriate for everyone. Discuss their benefits and risks with a healthcare professional rather than starting them solely for cancer prevention.
Manage diabetes with your healthcare team to protect your overall health. Diabetes is associated with endometrial cancer risk, but it is not clear that blood sugar control by itself lowers that risk.
Walking 30 minutes most days of the week is simple and very effective. Eating more vegetables and less processed food helps control weight and hormone levels. These changes help prevent many types of cancer and other diseases too.
The connection between lifestyle choices and cancer risk applies to many conditions. Making healthy changes benefits your entire body's functioning and disease resistance.
Frequently Asked Questions
Many endometrial cancers are successfully treated when found early. About 95% of patients whose cancer is confined to the uterus are alive five years after diagnosis, although outcomes vary by cancer type and other factors. Advanced endometrial cancer is harder to treat, but combinations of chemotherapy, immunotherapy, targeted therapy, radiation, or hormone therapy may control the disease in some patients.
Not all women need chemotherapy. Early-stage cancers usually require only surgery. Your doctor recommends chemotherapy based on factors like cancer stage, cell type, and risk of recurrence.
Standard treatment involves removing the uterus, which makes pregnancy impossible. However, some young women with very early-stage cancer may be candidates for hormone therapy that preserves the uterus. This requires careful discussion with specialists.
Follow-up is often more frequent during the first few years and less frequent later. The schedule depends on cancer type, stage, treatment, symptoms, and your care team's recommendations. Your specific schedule depends on your cancer stage and treatment type. Regular monitoring helps catch any recurrence early.
Surgery may cause early menopause if your ovaries are removed. Some women experience fatigue, lymphedema, or sexual function changes. Some side effects improve over time, while others—such as lymphedema or certain sexual-function changes—may persist and require ongoing management.
