Researchers found that some women carry genetic mutations that make tamoxifen less effective. They also found that women with this specific mutation were more likely to have a relapse.

The second study found that tamoxifen can boost the risk of endometrial cancer in both pre-menopausal and postmenopausal women.

The longer a woman takes the drug, the greater the risk.

Hearing And Your Brain, How Do They Work Together?

If you think of problems as you get older, you think of not seeing well as a problem with your eyes and not smelling as a problem with your nose. But problems with hearing may not be all in your ears.

Dr. Robert Frisina is a neuroscientist at the U of R and the lead researcher on a project wherein over a thousand people had their hearing tested.

First they tested the standard way with ear phones. (Testing basic hearing.)

Then Dr. Frisina tested how people heard through speakers. This method tests to see how the brain processes information the ear detects.

Frisina said, "When you think of age related hearing loss you think of your grandparents....not that it's a neuro situation."

So as the brain ages certain things begin to break down that could affect hearing. Even more surprising is how early this problem can start.

Dr. Frisina said, "I was surprised that things were happening already in middle age.”

The next step would be to try and come up with a pill or a supplement that could possibly correct the chemical imbalance that affects the brain and the ability to hear.

However, until that happens, the doctor said it's important to work on prevention.

Make sure you protect your hearing, and if you do find you have a problem, go to a specialist.
