status. Hormonal status of yours is not completely suppressed by tamoxien and persisting estrogen
activity does cause the discharge from the vagina. In the long run second malignancy from uterous is expected after long therapy of tamoxifen
. Hence it is recomonded that you should visit a gynaecologist to get pelvic examoination to rule out the development of new polyps and pap smear
examination done to see that your brownish vaginal discharge
is normal. this could be a normal physiological process.
