-
Constipation that is unusual for them.
-
A feeling of incomplete bowel movements.
-
Increased abdominal pressure.
-
Changes in the frequency of bowel movements.
-
Discomfort when passing stool.
However, constipation is extremely common and is often associated with inadequate fiber intake, dehydration, reduced physical activity, medication, or digestive disorders.
The presence of constipation alone is not a reliable indicator of ovarian cancer.
What matters is whether the symptom represents a significant change from your usual bowel habits and whether it continues over time.
If constipation is persistent, unexplained, or accompanied by abdominal swelling, pelvic pain, or early satiety, seek medical advice.
Blood in the stool, severe abdominal pain, vomiting, or an inability to pass stool or gas may indicate another urgent medical problem and should be assessed promptly.
6. Unexplained Weight Loss or Weight Changes
Unexpected weight changes can sometimes occur in women with ovarian cancer.
Some women lose weight because they experience reduced appetite, early satiety, or persistent digestive discomfort.
When eating becomes uncomfortable, they may gradually consume fewer calories than their bodies require.
Cancer can also affect metabolism and the body's use of energy.
However, not every woman with ovarian cancer loses weight.
Some women experience abdominal enlargement due to fluid accumulation, even while losing muscle or body weight elsewhere.
This can create a confusing situation in which the abdomen becomes larger while the rest of the body becomes thinner.
It is important to distinguish intentional weight loss from unexplained weight loss.
If you have not changed your diet, increased physical activity, or started a weight-management program, but your weight continues to decrease, consider arranging a medical evaluation.
Unexpected weight loss can be associated with numerous conditions, including thyroid disorders, diabetes, gastrointestinal diseases, chronic infections, and several types of cancer.
The key is to understand why the change is happening rather than simply accepting it as a normal part of aging.
7. Persistent Fatigue and Unusual Weakness
Feeling tired after a long day is normal. However, persistent fatigue that does not improve with adequate rest may deserve further investigation.
Some women with ovarian cancer experience ongoing exhaustion, reduced energy, and difficulty completing activities that previously felt easy.
This fatigue may result from several factors, including:
-
Reduced food intake.
-
Poor sleep caused by abdominal discomfort.
-
Anemia.
-
Inflammation associated with cancer.
-
Changes in metabolism.
-
Emotional stress related to ongoing symptoms.
Fatigue is one of the most nonspecific symptoms in medicine. It can be caused by iron deficiency, thyroid disease, sleep disorders, depression, infections, and many other conditions.
Nevertheless, unexplained fatigue combined with persistent bloating, pelvic pain, or changes in appetite should not be dismissed.
If you regularly wake up feeling exhausted despite sleeping sufficiently, consider discussing the problem with a healthcare professional.
A medical evaluation may include blood tests to investigate anemia, thyroid function, nutritional deficiencies, and other possible explanations.
8. Back Pain That Does Not Go Away
Back pain is extremely common and is usually associated with muscle strain, poor posture, prolonged sitting, spinal problems, or physical activity.
However, persistent lower back discomfort can sometimes occur in women with ovarian cancer.
The pelvis and lower abdomen contain structures located close to the lower back. A growing mass or pressure within the abdomen may contribute to discomfort that is felt in the back.
Some women describe a dull, persistent ache rather than a sudden or sharp injury-related pain.
Possible characteristics include:
-
Discomfort in the lower back.
-
Pain that continues despite ordinary rest.
-
A sensation of pressure around the pelvis and lower back.
-
Back discomfort accompanied by abdominal swelling.
-
Pain that occurs together with other unexplained symptoms.
Back pain by itself is not a reliable sign of ovarian cancer.
Most cases have more common musculoskeletal explanations.
However, if back pain is new, persistent, unexplained, or accompanied by other concerning changes, it is reasonable to seek medical advice.
Sudden severe back pain, leg weakness, numbness around the groin, or new loss of bladder or bowel control requires urgent assessment.
9. Menstrual Changes and Unusual Vaginal Bleeding
Changes in menstrual patterns can be associated with many reproductive health conditions.
Hormonal fluctuations, thyroid disorders, uterine fibroids, endometriosis, pregnancy, and perimenopause can all affect menstrual cycles.
Although abnormal vaginal bleeding is not among the most characteristic symptoms of ovarian cancer, it should never be ignored.
Women may notice:
-
Bleeding between menstrual periods.
-
Periods that become unusually heavy.
-
Unexpected spotting.
-
Changes in menstrual regularity.
-
Vaginal bleeding after menopause.
Bleeding after menopause is particularly important because it is never considered a normal menstrual event.
It can be caused by several conditions, including vaginal or uterine tissue changes, polyps, endometrial abnormalities, and cancer of the reproductive organs.
Ovarian cancer should not automatically be assumed to be the cause.
Nevertheless, any unexplained postmenopausal bleeding requires prompt medical evaluation.
Women should also understand that cervical cancer, uterine cancer, and ovarian cancer are different diseases. Their symptoms can overlap, but their diagnostic procedures and treatments are not identical.
10. Pain or Discomfort During Sexual Activity
Pain during sexual intercourse can be physically and emotionally distressing.
It may occur for several reasons, including vaginal dryness, infections, endometriosis, pelvic floor dysfunction, hormonal changes, and ovarian cysts.
In some women, ovarian cancer may contribute to pelvic discomfort that becomes more noticeable during sexual activity.
The pain may feel deep inside the pelvis rather than being limited to the vaginal opening.
Some women also experience pressure or abdominal discomfort afterward.
It is important not to feel embarrassed about discussing this symptom with a doctor.
Sexual discomfort is a legitimate medical concern, and healthcare professionals regularly evaluate it.
A proper examination can help determine whether the cause is related to infection, hormonal changes, reproductive organs, or another condition.
If pain during intercourse develops suddenly, persists, or occurs alongside other unexplained pelvic symptoms, arrange an evaluation.
11. Abdominal Enlargement or a Feeling of Pressure
Another possible sign of ovarian cancer is an increase in abdominal size.
This is different from ordinary bloating that disappears after passing gas or having a bowel movement.
Some women notice that their stomach gradually becomes larger over several weeks.
Clothing may feel tighter, and the abdomen may appear swollen even in the morning before eating.
One possible explanation is ascites, the accumulation of fluid inside the abdominal cavity.
Ascites can occur when cancer affects the lining of the abdomen or interferes with normal fluid balance.
The amount of fluid can vary significantly.
Some women experience mild swelling, while others develop substantial abdominal enlargement.
Other medical conditions, including liver disease, heart failure, and certain infections, can also cause ascites.
Therefore, abdominal swelling does not automatically indicate cancer.
However, unexplained or progressive abdominal enlargement should be evaluated by a medical professional.
If the swelling is accompanied by shortness of breath, severe pain, or rapidly worsening discomfort, seek urgent medical attention.
12. Nausea, Indigestion, and Persistent Digestive Discomfort
Digestive symptoms can sometimes be among the earliest complaints reported by women with ovarian cancer.
Some women experience nausea, indigestion, stomach pressure, or discomfort after eating.
These symptoms may be mistaken for ordinary digestive problems.
A woman might change her diet, avoid certain foods, or take antacids, assuming that the issue is caused by acid reflux or food intolerance.
In some cases, the symptoms may temporarily improve.
However, persistent digestive discomfort deserves attention when it is new or unusual.
Possible symptoms include:
-
Frequent indigestion.
-
Nausea without an obvious explanation.
-
Feeling uncomfortable after ordinary meals.
-
Abdominal pressure.
-
Reduced appetite.
-
Persistent bloating.
Digestive symptoms have many possible causes, and ovarian cancer is only one of several conditions doctors may consider.
