Brief Answer:
Advice to follow up with a Gynecologist

Detailed Answer:
Hello,
Thank you for trusting HCM

Brown discharge is indicative of presence of blood. Blood which is few days old can turn brown in color.
Brown vaginal discharge in post menopausal woman is no confirmative of cancer. However, it is a key symptom that warrants further evaluation to look for possible cancer.
Another important possibility is the presence of endometrial (uterine lining) atrophy and vaginal atrophy. Endometrial and vaginal atrophy is due to thinning and fragility of uterine and vaginal lining resulting In bleeding. This is a most predominant possibility in you especially since you have already been diagnosed with vaginal atrophy. The condition is treated with hormone replacement therapy.

I understand that you have been undergoing regular abdominal and pelvic imaging studies and cervical PAP smear testing. However, conditions like endometrial hyperplasia and presence of atypical cells (which predisposes to uterine cancer) cannot be picked by CT/MRI studies. An endometrial biopsy is indicated for this. So please be advised to follow up with your gynecologist at the earliest to undergo pelvic/vaginal examination and need for endometrial biopsy. Your Gynecologist will assess the need for endometrial biopsy by reviewing the size and thickness of uterus in your recent CT/MRI.

In short, even though atrophy of endometrium/vagina is an important possibility in your case, further investigations to rule out possible cancerous/pre cancerous cells in uterus should be done.
