Hi, I am 37 and was diagnosed with breast cancer since 2005. I hv finished Tamoxifen on April this year, and I am experiencing browny discharge after period which last at least a week. Also hv bleeding during sex. I hv tried to do a pap smear, however I got extremely painful when the thing open up in my virgina, so it cannot be done. Is it because I hv no regular sex during all these years which I was only a few times in 5 yrs ? What's wrong with me? Am I facing another cancer?
