Should I stop my Tamoxifen while doing chemo???

rn4babies

I started chemo on May 15th for a new primary dx. I have been on Tamoxifen since 2/1/12 from my first dx. My MO did not tell me to stop the Tamoxifen while on chemo but I know I know it's not usually started until after all the treatment is done, including radiation. Has anyone been in a situation where they were already on Tamoxifen and then had to do chemo? I'm going to post this on the reoccurance thread as well.  Thanks.
