Women who have brown discharge not during menstruation usually need to consider the following conditions: 1. Ovulatory bleeding. Ovulatory bleeding is a normal condition due to the rupture of the tiny capillaries around the egg during ovulation in the process of expelling the ovary, and the blood flowing out after the rupture of the blood vessels is mixed in the leucorrhoea, so it leads to brown leucorrhoea. 2. If there are cervical diseases, it can cause brown leucorrhoea, such as Cervical polyps, severe cervical erosion, cervical malignant lesions, etc. Cervical lesions are one of the most common diseases in women, so women of any age who have abnormal brown leucorrhea are advised to have cancer screening of the cervix. 3. If there is pelvic inflammatory disease, abnormal vaginal bleeding is also easily caused when women are overworked, leading to brown leucorrhea.
