The brownish color of leukorrhea may be cervical cancer, but it can also be seen in many other diseases. It is recommended to go to gynecology department in time to find out the specific cause. Normal leukorrhea is milky white, transparent and odorless. Brownish leucorrhea indicates blood in the leucorrhea, which mostly comes from the uterine cavity, cervical or vaginal lesions. Brownish color indicates that blood has been retained in the vagina for a certain period of time, which may be cervical cancer. Cervical cancer often manifests as contact bleeding, such as vaginal bleeding during sex or gynecological examination. If blood from the vagina is combined with leukorrhea, bloody leukorrhea will appear. If the bloody leukorrhea stays in the vagina, the leukorrhea may appear brownish in color. In addition, apart from cervical cancer, brownish leucorrhea may occur due to birth control device, chronic inflammation of the cervix, postpartum and post-abortion, etc. Detailed examination at the hospital is required to confirm the diagnosis. If brownish leucorrhea occurs, patients should not worry too much and can undergo colposcopy, cervical cell and HPV examination and, if necessary, cervical biopsy, tumor markers and hysteroscopy for clear diagnosis.
