Postmenopausal bleeding or discharge?


Hello Doctor, I am inquiring on behalf of my mother.
She is 68 years old and has been postmenopausal for some time.
Two months ago, she experienced occasional bleeding, which was dark in color.
She went to the hospital for examinations, including a Pap smear and a transvaginal ultrasound, but no abnormalities were found.
After taking medication prescribed by the doctor a few times, the bleeding stopped.
However, starting last week, she noticed a discharge, which this time is yellow in color, different from the previous red discharge.
I would like to ask the doctor, if she has already taken medication and undergone an ultrasound examination, what could this issue be? Thank you! (My mother has Parkinson's disease and has been on medication for a long time, and she had breast cancer over a decade ago.)

Lin, 60~69 year old female. Ask Date: 2022/11/14

Post-menopausal bleeding and discharge can be concerning, especially in a 68-year-old woman with a history of breast cancer and ongoing medication for Parkinson's disease. It’s good to hear that your mother has already undergone some diagnostic tests, including a Pap smear and a vaginal ultrasound, which did not reveal any abnormalities. However, the recurrence of bleeding and the appearance of yellow discharge warrant further attention.

Firstly, it’s important to understand that any bleeding after menopause is considered abnormal and should be evaluated thoroughly. While the initial tests were normal, the new symptoms suggest that there may still be an underlying issue that needs to be addressed. The fact that the discharge has changed from red to yellow could indicate a few possibilities:
1. Infection: The yellow discharge could suggest a vaginal infection, such as bacterial vaginosis or a yeast infection. These infections can sometimes cause changes in discharge and may not always be detected during an ultrasound. It would be prudent for your mother to be evaluated for any signs of infection, which may require a different set of tests, such as a vaginal swab.

2. Hormonal Changes: Post-menopausal women experience significant hormonal changes that can lead to various symptoms, including changes in vaginal discharge. Hormonal imbalances can sometimes cause the lining of the uterus to shed irregularly, leading to bleeding or discharge.
3. Endometrial Hyperplasia: This condition, which involves thickening of the uterine lining, can occur in post-menopausal women and may lead to abnormal bleeding. Although your mother had an ultrasound, it may be necessary to consider further evaluation, such as an endometrial biopsy, especially given her history of breast cancer.

4. Polyps or Fibroids: Uterine polyps or fibroids can also cause post-menopausal bleeding. These growths may not always be visible on an ultrasound, and further investigation may be required.

5. Cancer: While it’s important to consider the less common but serious possibility of endometrial cancer, especially given your mother's history of breast cancer, it’s crucial to approach this with caution. The fact that she has had previous screenings is reassuring, but any new symptoms should prompt further investigation.

Given your mother’s medical history and the recent changes in her symptoms, it is advisable to follow up with her healthcare provider. They may recommend additional tests, such as a pelvic exam, cultures for infections, or possibly an endometrial biopsy to rule out any serious conditions. It’s also essential to keep an open line of communication with her doctor about any new symptoms, changes in her condition, or concerns regarding her medications for Parkinson's disease, as these can sometimes interact with other health issues.

In summary, while the initial tests were normal, the recurrence of bleeding and the presence of yellow discharge should not be ignored. It’s essential to seek further evaluation to ensure that any potential issues are identified and treated promptly. Your mother’s health and well-being are paramount, and proactive management of her symptoms will help in addressing any underlying concerns.
