Occasional small amount of brown discharge after menopause is considered to be abnormal vaginal bleeding, which is generally considered to be related to vaginitis, ovarian cancer, endometrial cancer, cervical cancer and other causes. It is recommended to consult a doctor in time to find out the cause and treat it under the doctor’s guidance. 1. Vaginitis: Generally speaking, after menopause, due to the decrease of estrogen level, there will be atrophy of reproductive organs, and if there is bacterial infection or fungal infection, brown secretion will easily appear. 2. Ovarian cancer: if suffering from functional ovarian malignant tumor, it will also lead to irregular bleeding after menopause, and the amount of bleeding is relatively small, then it will show brown secretion. 3. Endometrial cancer: after menopause, if there is abnormal vaginal bleeding, it may be due to endometrial lesions, and it may also be accompanied by abnormal vaginal secretion, which may appear plasma or pus secretion. 4. Cervical cancer: If there is irregular vaginal bleeding after menopause, especially contact bleeding, one should also consider whether it is caused by cervical lesions. If you have abnormal brown secretion occasionally after menopause, you need to consult a doctor in time to find out the cause and treat the symptoms.
