Warning Signs of Ovarian Cancer That Many Women Overlook Until It Spreads

Frequent bloating and persistent abdominal discomfort are warning signs of ovarian cancer that many women overlook, thinking symptoms will resolve on their own until the disease has already spread. Dr. Jed Boonywongviroj, Deputy Director of Primary Care at Nakhon Ratchasima Hospital, posted on Facebook under the handle "Dr. Jed" to educate the public about ovarian cancer, highlighting that frequent bloating and persistent abdominal pain are ovarian cancer symptoms women commonly miss. Many women experiencing unusual symptoms assume they will pass on their own—attributing mild bloating, abdominal pain, or slight menstrual irregularities to stress, hormones, or fatigue. The alarming aspect of ovarian cancer is that it often shows no clear symptoms in early stages, and the symptoms that do appear resemble ordinary daily complaints, causing many women to delay treatment until the disease has already advanced.

1. Frequent bloating and abdominal distension, even without eating much: This symptom is commonly overlooked because women assume it's just intestinal gas or indigestion. However, if bloating occurs frequently, with easy abdominal distension, abnormal early fullness, and persists for several weeks, this should not be ignored. Masses or abnormalities in the ovaries may begin pressing on or disrupting the abdominal cavity.

2. Mild abdominal or unusual back pain: Many assume this indicates an approaching period or pain from prolonged sitting, but persistent dull pain in the lower abdomen, chronic lower abdominal pain, or unexplained back pain—especially occurring almost daily—warrants medical evaluation. Symptoms may come and go, causing many people to become accustomed to them.

3. Increased urination without increased fluid intake: If a mass or abnormality exists in the pelvic region, it may press on the bladder, causing frequent painful urination, incomplete bladder emptying, or more frequent bathroom visits without a urinary tract infection. Some women may experience increased nighttime urination, which never occurred before.

4. Early satiety and reduced food intake: Some dismiss this as beneficial for weight loss, but if you feel full after eating only a small amount and gradually eat less than usual in an abnormal way, this may signal something in the abdominal cavity is disrupting your digestive system. Combined with bloating, this persistent symptom should not be ignored for months.

5. Irregular menstruation or unusual bleeding: This doesn't mean every ovarian cancer patient experiences bleeding, but if your period becomes irregular, with sporadic bleeding, bleeding after the period ends, or significant changes in your menstrual cycle without prior occurrence, you should get checked. This is especially important for women over 40 or those experiencing noticeably irregular periods.

6. Unexplained weight loss and easy fatigue: Some people lose weight without reducing food intake or exercising, feel easily tired, weak, and lack energy. This signals your body may be experiencing inflammation or some abnormality. Don't dismiss weight loss as simply beneficial; your body may be expending energy abnormally due to hidden disease.

7. Early-stage ovarian cancer is often quieter than expected: This is what's frightening—it doesn't present a palpable mass like some diseases, and early symptoms resemble gastric, intestinal, or common hormonal issues. Many people receive wrong treatment for months or years before proper diagnosis, by which time the cancer has already progressed. This is especially true for those who dismiss minor symptoms as insignificant.

8. High-risk individuals should be especially vigilant: Particularly those with a family history of ovarian cancer, breast cancer, no children, obesity, or advanced age. This doesn't mean you'll definitely develop the disease, but you should be extra cautious, pay closer attention to your body, and not ignore persistent symptoms, including those with relevant risk factors.
