Ovarian cancer is a relatively common disease, the early symptoms are not obvious, and many people have already reached advanced stage once they are found, so it greatly affects the life and health of patients, so it is very necessary to understand the symptoms of ovarian cancer. Ovarian cancer will appear as abdominal pain and low back pain. Ovarian cancer will infiltrate the surrounding tissues and cause adhesions, which will compress the nerves and lead to abdominal pain and low back pain, often manifesting as hidden pain or dull pain, or even more severe pain, which is often more serious once ovarian cancer occurs. Ovarian cancer will lead to edema of lower limbs and vulva. If ovarian cancer grows in the pelvic cavity, it will compress the pelvic veins and affect the lymphatic flow, which will lead to edema of lower limbs and vulva after a long time. Ovarian cancer may cause menorrhagia or amenorrhea Generally, ovarian cancer does not affect menstruation, but if ovarian cancer destroys normal tissues, the patient may suffer from poor general condition, resulting in menorrhagia or amenorrhea. Ovarian cancer can cause sex hormone disorders. Ovarian cancer tumors sometimes secrete estrogen, which can lead to precocious puberty and menstrual disorders or vaginal bleeding after menopause. Patients with ovarian cancer may experience abdominal distension. Abdominal distension is often caused by the pressure of the tumor itself and the pulling of the surrounding ligaments in the abdominal cavity, while ascites may also cause abdominal distension, which often exists when the mass is not touched in the abdomen.
