15 Signs of Endometrial Cancer

2. Vaginal Discharge

Vaginal discharge can be an early sign of endometrial cancer. You may notice a change in the color, smell, or amount of fluid from your vagina. It may look watery, pink, brown, or mixed with blood. Discharge that is new or unusual for you matters, especially after menopause. Any discharge after your periods have stopped is not normal. It is important to pay attention if it happens between periods.

Some people notice a thin, clear, or slightly bloody fluid that continues for days or weeks. Others may see a heavier flow that feels different from a normal period. The change may be subtle at first. You might also notice a mild odor. While infections can also cause odor and discharge, cancer-related discharge often does not come with itching or burning.

Keeping track of when the discharge starts and how long it lasts is important. Noting other symptoms, such as pelvic pain or pressure, is also important. Changes in discharge do not always mean cancer, but ignoring them can delay diagnosis.

3. Painful Urination

You may notice pain or a burning feeling when you urinate. This symptom is not common in early endometrial cancer, but it can happen when the cancer affects nearby tissues in the pelvis. The uterus sits close to the bladder. If a tumor grows large or spreads, it can press on the bladder or urinary tract and cause discomfort, a stinging feeling, or trouble starting your urine stream.

You might also feel the need to urinate more often. Some people report pelvic pressure along with urinary pain. These symptoms can feel similar to a urinary tract infection, which makes them easy to overlook. If painful urination happens along with abnormal vaginal bleeding, unusual discharge, or pelvic pain, it may point to a deeper issue. Bleeding after menopause is never normal and should not be ignored.

Many conditions can cause urinary pain, including infections and bladder problems. When this symptom appears with other warning signs of endometrial cancer, it’s important to seek medical review.

4. Enlarged Uterus

As cancer cells grow inside the lining of your uterus, they can cause the organ to increase in size. This growth may lead to a feeling of fullness or heaviness in your lower belly. You might also feel pressure between your hip bones. Some women notice a visible or firm swelling in the lower abdomen. Your clothes may feel tighter around your waist without weight gain. This change often develops slowly.

An enlarged uterus can also press on nearby organs, which makes you feel the need to urinate more often. Some women report changes in bowel habits, such as going more or less often than usual. Other conditions can also cause your uterus to grow, such as fibroids or hormone changes. If you have this sign along with abnormal vaginal bleeding, pelvic pain, or unusual discharge, it raises concern. A pelvic exam allows your doctor to check the size and shape of your uterus. Imaging tests like an ultrasound may follow if the uterus feels larger than expected.

5. Pain During Intercourse

You may feel pain during intercourse if endometrial cancer affects the uterus or nearby tissues. This pain can feel sharp, aching, or like deep pressure in your pelvis. It may happen during penetration or with deeper movement. Endometrial cancer can cause changes in the lining of your uterus, which leads to swelling, irritation, or a mass inside the uterus. When this happens, sexual activity can trigger discomfort.

You might also notice other symptoms at the same time, such as abnormal vaginal bleeding or unusual discharge. Pelvic pressure or a feeling of fullness can occur as well. When these signs appear together, they may point to a problem inside your uterus. Pain during intercourse does not always mean cancer. Infections, hormonal changes, or vaginal dryness can also cause discomfort. If the pain is new, ongoing, or paired with unusual bleeding, medical evaluation is necessary.

6. Vaginal Soreness

Endometrial cancer can cause changes in the tissues of your uterus and vagina, which leads to inflammation or unusual discharge. When this happens, the skin inside your vagina can become sensitive and sore. You might feel burning or stinging, pain during sex, discomfort when sitting for long periods, or irritation that does not improve.

Vaginal soreness often appears along with other symptoms. Abnormal bleeding, spotting after menopause, or unusual discharge may happen at the same time. Bleeding after your periods have stopped is never normal and needs attention.

In some cases, cancer can grow and press on nearby tissues, which increases pelvic discomfort and makes soreness worse. You may also notice lower back pain or a feeling of fullness in your lower belly. Many common conditions can also cause vaginal soreness, such as infections or dryness. Ongoing pain that does not improve or comes with abnormal bleeding should not be ignored.

7. Unexpected Weight Loss

You may notice weight loss that you did not plan or try to achieve. Your clothes may fit looser, or the number on the scale may drop over a few months without changes in diet or exercise. This type of weight loss can be a warning sign of a serious health problem. Endometrial cancer can affect how your body uses energy. Cancer cells may grow and spread, which can raise your body’s energy needs. As a result, you may burn more calories than usual, even when you rest.

You might also lose weight because you feel less hungry. Pelvic pain, pressure, or ongoing vaginal bleeding can lower your appetite. Stress about your health can also make it hard to eat regular meals. Unplanned weight loss often appears along with other symptoms. These include abnormal vaginal bleeding, especially after menopause, pelvic pain or pressure, unusual vaginal discharge, and fatigue or low energy.

8. Lower Body Pain

You may feel pain in your lower belly or pelvis, which sits between your hip bones and below your stomach. The pain can feel dull, sharp, or like strong cramps. Some people notice pelvic cramping that does not match their normal period pattern. Others feel steady pressure that does not go away. This pain can come and go, or it can stay for days or weeks. As endometrial cancer grows, it can press on nearby tissues and cause aching in your lower back or deep in your pelvis. You might also feel pain during sex.

In some cases, you may notice changes in how often you pee or have bowel movements. Pressure in the pelvis can affect the bladder or bowels. You may go more often, less often, or feel discomfort when you do.

Lower body pain is common and often links to less serious problems. Pain that is new, unusual for you, or does not improve requires medical evaluation. Careful attention is important when it occurs along with abnormal vaginal bleeding or unusual discharge.

9. Lethargy

You may feel very tired even when you get enough rest. This type of fatigue does not improve with sleep and can make daily tasks feel harder than usual. Lethargy linked to endometrial cancer often develops slowly. You might notice low energy, weakness, or a lack of motivation. Some people describe it as feeling drained most of the day.

Ongoing blood loss can lead to anemia, which means your body does not have enough healthy red blood cells. When this happens, your body carries less oxygen, and you feel tired more easily.

You may also feel short of breath during simple activities. Climbing stairs or walking short distances can leave you worn out. Headaches, pale skin, or dizziness can appear along with fatigue. Your immune system stays active as it tries to respond to abnormal cells. This process can increase inflammation and make you feel weak or sluggish.

10. Sickness

You may feel sick to your stomach if you have endometrial cancer. This can include nausea, loss of appetite, or a general feeling of being unwell. Some people describe it as a constant upset stomach that does not improve. Sickness often appears with other warning signs, such as abnormal vaginal bleeding, unusual discharge, or pelvic pain. When your body fights disease, it can affect how your stomach feels and how much you want to eat.

Ongoing sickness can lead to weight loss. You may lose weight without trying or changing your diet. This happens because your body uses more energy when cancer grows, and you may eat less due to nausea.

In later stages, cancer can press on nearby organs, which increases nausea or causes bloating. You may also feel tired and weak at the same time. Short-term stomach illness is common and often harmless but sickness that continues, especially along with unusual bleeding or pelvic pressure, needs medical attention.

11. Unusual Periods

Your period may change in unexpected ways, such as heavier bleeding or longer duration. You might also experience irregular cycles or bleeding between periods. These changes can signal underlying health issues that require attention. Heavy bleeding can mean soaking through a pad or tampon every hour for several hours. You might pass large blood clots, and some people feel weak or tired from the blood loss.

Bleeding between periods is another warning sign. You may spot for a few days or have light bleeding at times when you do not expect it. Even small amounts of bleeding between cycles matter. If you have already gone through menopause, any bleeding is not normal. Your periods should have stopped for good. Spotting or bleeding after menopause needs medical care.

Your cycle may also become irregular without a clear reason. For example, your period may come much earlier or later than usual, you may skip months and then bleed heavily, or your flow may change from light to very heavy.

12. Bleeding Post Menopause

Bleeding after menopause is not normal. Menopause means your periods have stopped for 12 months in a row. Any postmenopausal bleeding requires attention. You may notice spotting, light staining, or a flow similar to a period. Even a small amount of blood on your underwear or toilet paper matters. The color can be bright red, pink, or brown. Endometrial cancer often causes bleeding after menopause. In many cases, this is the first and only early sign. The bleeding may happen once, or it may come and go.

Other problems can also cause postmenopausal bleeding. These include thinning of the vaginal lining due to low estrogen, small growths called polyps, or a thickened uterine lining. Hormone therapy and certain cancer treatments can also raise your risk. You cannot tell the cause by the amount of blood alone as light spotting can also signal a problem. If you have already gone through menopause and notice any bleeding, prompt medical assessment is necessary.

13. Mood Swings

You may notice changes in your mood that feel stronger or happen more often than usual. You might feel irritable, sad, or anxious without a clear reason. These shifts can seem sudden and hard to control.

Hormone changes linked to endometrial cancer can affect how you feel. The lining of your uterus responds to estrogen, and changes in hormone levels may also affect your brain. When hormones shift, your mood can change too.

Mood swings may also connect to other symptoms. Ongoing pelvic pain, pressure, or abnormal vaginal bleeding can cause stress. Worry about unexplained symptoms can add to feelings of fear or frustration. You might also feel more tired than usual. Fatigue can lower your patience and make small problems feel bigger. Poor sleep from pain or discomfort can make mood changes worse.

14. Difficulty Getting Pregnant

You may notice trouble getting pregnant if endometrial cancer affects the lining of your uterus. The uterus needs a healthy lining to support a fertilized egg. When cancer changes this lining, implantation can become harder. Endometrial cancer often links to hormone imbalance, especially too much estrogen without enough progesterone. This imbalance can cause the uterine lining to grow too thick. Over time, these changes may lead to abnormal cells and interfere with normal ovulation or implantation.

You might also have irregular periods, very heavy bleeding, or bleeding between cycles. These problems can make it harder to track ovulation and plan pregnancy. In some cases, infertility appears before cancer is found.

Trouble getting pregnant has many possible causes, such as ovulation problems, blocked fallopian tubes, or issues with sperm. Doctors may use imaging tests or take a small tissue sample from the uterine lining to check for abnormal cells.

15. Risk Factors

Several factors can raise your risk of endometrial cancer, especially age, hormone levels, and family history. Most cases occur after menopause, usually between ages 50 and 70. Your weight, certain health conditions, and some treatments also play a role.

Hormone levels also matter. If your body has higher levels of estrogen without enough progesterone, the lining of your uterus can grow too much. This overgrowth can increase cancer risk. Using estrogen-only hormone therapy after menopause, starting your periods at a young age, or reaching menopause late can raise your lifetime exposure to estrogen.

Your weight affects risk as well. Fat tissue makes extra estrogen, which can change the balance of your hormones. If you have obesity, your body may produce more estrogen than it needs.

Certain health conditions increase risk. These include polycystic ovary syndrome, diabetes, and a history of irregular periods. If you have never been pregnant, your risk is also slightly higher. Family history matters. If close relatives had endometrial or colorectal cancer, your risk may rise, especially if your family carries an inherited gene condition linked to these cancers.
