Hi, I have been on Tamoxifen for about 2 years now, and Zalodex for about 1.5 years.

  • while I was on Tamoxifen for about 3-4 months (before Zalodex), my period returned.

  • it then stopped after I am on Zalodex.


A few days ago, I notice slight bleeding (period like, but not heavy) from my vagina.


  1. Is this called vagina bleeding ? Or is it called period ?


  1. Why does this happen ? I thought with Zalodex, my period stops until I stop taking Zalodex ? 


  1. What kind of scan is suitable for this situation I am in ?


Feeling quite concern.

Hi Cecilia Rose Ann
I was just wondering what happened re this?
Did you get it checked out? I have been on zoladex for nearly two years as well as tamoxifen and I have just started having some bleeding too (feels like the end of a period)…
I will speak to someone to get it checked but wondered if you resolved it xx
