Ovarian cancer is one of the most common genital cancers in women, according to Doctor Luu Thao Ngoc, an oncologist at Tam Anh General Hospital in Hanoi. Even after successful treatment, there is still a risk of recurrence. Early detection of signs of recurrence helps patients receive timely treatment, increases effectiveness, and improves quality of life.

Persistent digestive disorders are the most common symptom of recurrent ovarian cancer, but they are easily overlooked because they resemble common digestive problems, Dr. Thao explains. This is caused by fluid buildup in the abdomen (also known as ascites) or a tumor pressing on the intestines. Patients may feel bloated and distended for a long time, and the symptoms don't subside even with dietary changes or digestive aids. If patients experience indigestion, changes in bowel habits such as persistent constipation or diarrhea without a clear cause, they should see a doctor for a check-up.

Persistent pain in the abdomen and pelvis can be a sign of recurrent ovarian cancer. Patients may experience a dull, heavy, or persistent stabbing pain in the lower abdomen or pelvic area that is not related to the menstrual cycle (for premenopausal women) or pain that does not subside even with pain medication. The pain tends to increase as the tumor continues to grow and presses on neighboring organs.

Frequent urination is another common symptom. The tumor pressing on the bladder can cause urinary problems such as frequent urination and a constant feeling of needing to urinate.

General signs such as unexplained weight loss, persistent fatigue, exhaustion, lethargy despite adequate rest, loss of appetite, and poor absorption can also warn of recurrent ovarian cancer.

Distant metastasis can cause some symptoms such as shortness of breath, persistent cough, and chest pain if the cancer has spread to the lungs or pleura (causing pleural effusion). If the tumor metastasizes to the liver, the patient may experience jaundice, fatigue, and elevated liver enzymes. Patients may also experience bone pain, especially in the spine and pelvis, when the cancer spreads to the bones; and leg swelling due to compression of lymphatic vessels or veins.

Dr. Ngoc advises ovarian cancer patients to have regular follow-up appointments as scheduled by their doctor. Depending on the situation, the doctor may order tests such as checking the CA-125 level in the blood, clinical examination, along with imaging diagnostics (ultrasound, CT, MRI, PET) to help detect recurrence early. From there, the doctor can promptly diagnose and provide appropriate treatment, improving the patient's quality of life.
