It is not normal to have watery leucorrhea, so it is recommended to go to a regular hospital for examination in time. There are many reasons for watery leucorrhea. If intermittent discharge of clear, yellow-red or red watery leucorrhea occurs, it is generally considered that it may be tubal cancer. Among them, vaginal discharge is an important clinical symptom of tubal cancer, which is mostly plasma or plasma-blood, with varying amount, mostly without odor, and lower abdominal cramps or relative relief after vaginal discharge. If the discharge is heavy, persistent, pale milky white and with a strange odor, it is usually associated with adenocarcinoma of the cervical canal, advanced cervical cancer, vaginal cancer or submucosal fibroids with infection. Vaginitis or cervical inflammation can also cause draining leucorrhea. It is recommended to go to a regular hospital for a timely examination to clarify the cause and treat accordingly.
