Uterine cancer is a disease where cells in the uterus grow out of control, forming tumors that can spread to other parts of the body. This cancer affects the reproductive organ where a baby grows during pregnancy, making it a serious concern for women’s health.
Quick Facts About Uterine Cancer:
- Most common type: Endometrial cancer (starts in the uterine lining)
- Main symptom: Abnormal vaginal bleeding, especially after menopause
- Who’s at risk: Women over 50, especially those who are postmenopausal
- Survival rate: 81.2% five-year survival rate when caught early
- Annual cases: Over 65,000 new diagnoses in the United States each year
Uterine cancer is actually the most common cancer of the female reproductive system. The good news? When caught early, it’s often highly treatable. Most cases (about 95%) are endometrial cancer, which begins in the endometrium – the lining of your uterus. The remaining cases are uterine sarcomas, which are rarer but more aggressive.
The key to better outcomes is early detection. That’s why understanding the warning signs, knowing your risk factors, and maintaining regular gynecologic care are so important.
I’m Dr. Matthew Casavant, and I’ve been helping women steer complex gynecologic conditions, including uterine cancer, for over 20 years through advanced minimally invasive surgical techniques and comprehensive care. My experience treating uterine cancer has shown me how crucial it is for women to have clear, compassionate information about this condition so they can make informed decisions about their health.

Understanding the Types of Uterine Cancer
The term uterine cancer covers several diseases that can develop in the uterus, each with unique characteristics. Understanding these differences is crucial for creating an effective treatment plan.

Over 90% of cases are endometrial cancers, which start in the uterine lining. The rest are primarily uterine sarcomas, which are rarer and more aggressive.
Endometrial Cancer: The Most Common Form
If you’re diagnosed with uterine cancer, it is most likely endometrial cancer. This type begins in the endometrium, the inner lining of the uterus. Most are a type of adenocarcinoma called endometrioid adenocarcinoma, which is often caught early because it causes noticeable bleeding, leading to better treatment outcomes.
Less common but more aggressive subtypes include serous adenocarcinoma and carcinosarcoma, which can spread more easily and be more challenging to treat. The encouraging news is that endometrial cancer typically announces itself with abnormal bleeding, especially after menopause, which often leads to an early diagnosis.

Uterine Sarcoma: A Rarer, More Aggressive Type
Uterine sarcomas develop in the myometrium, the muscular wall of the uterus, and account for less than 4% of all uterine cancer cases. The most common type is leiomyosarcoma, which develops from smooth muscle cells. Endometrial stromal sarcoma is even rarer and typically grows more slowly. Because they are rare and aggressive, uterine sarcomas require specialized care and can be harder to diagnose early as they don’t always cause obvious bleeding.

Gestational Trophoblastic Disease (GTD)
While not technically uterine cancer, Gestational Trophoblastic Disease (GTD) involves pregnancy-related tumors that develop in the uterus from abnormal placental cells. These conditions, such as a hydatidiform mole or the rarer choriocarcinoma, are monitored through hCG hormone levels. Even when cancerous, GTD is highly treatable, and most women can have healthy pregnancies afterward.
Recognizing the Signs and Assessing Your Risk
Uterine cancer often provides clear warning signs, which is good news because it allows for early detection when treatment is most effective. The key is to know what to watch for and understand your personal risk factors.
Common Symptoms of Uterine Cancer
Abnormal vaginal bleeding is the most important symptom, appearing in about 90% of women with uterine cancer.
- For premenopausal women: This means bleeding between periods, or periods that are heavier or longer than usual.
- For postmenopausal women: Any vaginal bleeding or spotting is considered abnormal and requires immediate medical attention. Do not “wait and see.”
Other symptoms to watch for include:
- Abnormal vaginal discharge (watery, blood-streaked, or with an unusual odor).
- Pelvic pain or pressure, like a constant fullness or ache.
- Pain during intercourse.
- Changes in bathroom habits, such as frequent urination or difficulty with bowel movements.
- In advanced cases, unexplained weight loss or feeling full quickly.
These symptoms can also be caused by less serious conditions like fibroids or polyps, so a professional evaluation is essential for a correct diagnosis.

Key Risk Factors You Should Know
Many risk factors for uterine cancer relate to a lifetime of exposure to the hormone estrogen.
- Obesity: This is a major risk factor, as fat tissue produces estrogen. Maintaining a healthy weight can significantly lower your risk.
- Hormone-related factors: Starting periods before age 12, late menopause (after 55), or never having been pregnant can increase risk due to prolonged estrogen exposure.
- Polycystic Ovarian Syndrome (PCOS): This condition often leads to a hormone imbalance with high estrogen levels.
- Tamoxifen use: This breast cancer treatment can increase uterine cancer risk, requiring closer monitoring.
- Age: Most cases are diagnosed in women between 50 and 60.
- Previous pelvic radiation therapy: This can increase risk later in life.
Having risk factors doesn’t guarantee you’ll get cancer, but it helps identify who may need closer monitoring.

Genetic Links and Inherited Risk for Uterine Cancer
While most uterine cancers are not hereditary, about 5-10% are linked to inherited genetic mutations.
- Lynch Syndrome: This is the most common inherited cause, significantly increasing the risk for endometrial, colon, and ovarian cancer. The genes involved include MLH1, MLH2, MSH6, and PMS2.
- BRCA mutations: Known for their link to breast and ovarian cancer, they can also slightly increase the risk for certain aggressive types of uterine cancer.
If you have a strong family history of these cancers, genetic counseling can help you understand your risk and make informed decisions about screening and prevention. Uterine sarcomas, however, are rarely linked to inherited genetics.
The Path to Diagnosis and Staging
When you report concerning symptoms, the journey to a diagnosis begins. Prompt evaluation makes a significant difference, and our team is here to guide you through each step with clarity.

The diagnostic process is thorough, starting with simple tests and progressing as needed to build a complete picture of your health.
How Doctors Diagnose Uterine Cancer
Your evaluation will likely begin with a pelvic exam to feel for any abnormalities. This is often followed by a transvaginal ultrasound, which uses sound waves to create images of your reproductive organs and measure the thickness of your endometrial lining.

The definitive diagnostic tool is the endometrial biopsy. In this quick office procedure, a small tissue sample is taken from the uterine lining and sent to a lab to be checked for cancer cells.

If a closer look is needed, a hysteroscopy may be performed. This involves inserting a thin, lighted camera into the uterus to visually inspect the lining and take targeted biopsies. For a larger tissue sample, a dilation and curettage (D&C), a minor surgical procedure, might be recommended. Once cancer is confirmed, CT or MRI scans can help determine if it has spread.
Understanding Cancer Staging
Staging determines the extent of the cancer and guides your treatment plan. We use the FIGO staging system, which has four main stages:
- Stage I: Cancer is confined to the uterus. (Most cases are found at this stage).
- Stage II: Cancer has spread to the cervix.
- Stage III: Cancer has spread to nearby tissues or lymph nodes in the pelvis or abdomen.
- Stage IV: Cancer has spread to distant organs like the lungs, liver, or bones.
Nearly 70% of women are diagnosed at Stage I, which is excellent news for treatment success. Lower stages generally mean better outcomes, but we will discuss what your specific stage means for your personalized treatment plan.

Our goal is to cure the cancer when possible, especially when caught early. For advanced disease, we focus on controlling the cancer while maintaining your quality of life. Your plan will depend on the cancer type, its stage, your overall health, and your personal preferences.
Surgical Interventions
Surgery is the cornerstone of uterine cancer treatment and is often curative.
- Hysterectomy: The most common procedure is the removal of the uterus and cervix.
More info about What is a Hysterectomy?. - Bilateral Salpingo-oophorectomy: We often remove both fallopian tubes and ovaries, especially in postmenopausal women, to eliminate a source of estrogen that can fuel cancer growth.
- Lymph Node Removal: To check if the cancer has spread, we may remove lymph nodes. We often use a sentinel lymph node biopsy to remove only the most critical nodes, reducing side effects.
Whenever possible, we use minimally invasive surgical techniques like laparoscopic or robotic surgery. These methods involve smaller incisions, leading to less pain, shorter hospital stays, and faster recovery.
Radiation, Chemotherapy, and Hormone Therapy
Additional therapies may be used to target any remaining cancer cells after surgery or to treat cancer that has spread.
- Radiation Therapy: Uses high-energy beams to destroy cancer cells. It can be delivered internally (brachytherapy) or externally (external beam radiation).
- Chemotherapy: Uses powerful drugs, often given by IV, to kill cancer cells throughout the body. Side effects are much more manageable today with modern supportive care.
- Hormone Therapy: For hormone-sensitive cancers, drugs like progestin can block hormones that help cancer grow. This is often used for early-stage, low-grade cancers.
- Targeted Therapy and Immunotherapy: These newer treatments are exciting advances. Targeted drugs attack specific features of cancer cells, while immunotherapy helps your own immune system fight the cancer. Drugs like pembrolizumab can be highly effective for cancers with certain genetic markers.
Prevention, Outlook, and Recent Advances
While not all risk factors are controllable, you can take meaningful steps to protect your health. The outlook for women with uterine cancer is better than ever, thanks to ongoing research and treatment advances.
Can Uterine Cancer Be Prevented?
Making certain lifestyle choices can significantly reduce your risk.
- Maintain a healthy weight: This is the most impactful step, as excess body fat produces estrogen that can fuel cancer growth.
- Stay physically active: Regular exercise helps reduce cancer risk, even without dramatic weight changes.
- Manage hormone exposure: If you use hormone replacement therapy, discuss using a combination of estrogen and progestin with your doctor. Using birth control pills for at least a year has also been shown to lower risk.
- Regular monitoring: If you have a condition like PCOS or take tamoxifen, regular checkups are crucial for managing risk.
While there is no routine screening test, regular gynecologic visits are the perfect time to discuss your personal risk.

Understanding the Prognosis and Survival Rates
The outlook for uterine cancer is very positive, especially with early detection. The overall 5-year survival rate is 81.2%.
- Stage at diagnosis is key: For cancer confined to the uterus (Stage I), the 5-year survival rate is about 95%. This highlights the importance of reporting symptoms like abnormal bleeding promptly.
- For regional spread: The rate is a hopeful 69%.
- For distant spread: The rate is 17%, but new treatments are continuously improving these outcomes.
Your specific prognosis also depends on the cancer type, grade, and your overall health. These statistics are averages; many patients exceed expectations.
