Health Alert: Tamoxifen

Updated: Wednesday, December 17 2014, 04:11 PM EST
CINCINNATI (Liz Bonis) -- A study released has new information about Tamoxifen, a drug used to help fight breast cancer.
Tamoxifen is a drug often given to women after breast cancer treatment to reduce the odds of recurrence.  The study found that exposure to dim light night at night in lab experiments might make the body in some people more resistant to this drug.  The study was published in the Journal Cancer Research.

Researchers in the study looked in the lab experiments who got a little light overnight and those that did not.  They found that drug resistance goes up, or appears to, in those who get small amounts of light.  Something such as what comes through the bedroom window or maybe even light from a cell phone or street light.

Researchers said they need to do follow up studies to find out two things, how much light and whether or not a person could take the supplement melatonin to reduce these odds.  It's important to note these were lab experiments.  If a person is taking this medication it's just something to know and something to talk to their own doctors about until follow up studies are completed.
