Alcohol may increase breast cancer risk

 Drinking alcohol can increase risk of breast cancer by increasing levels of a cancer-causing gene, a study said.

 
"Our research shows alcohol enhances the actions of estrogen in driving the growth of breast cancer cells and diminishes the effects of the cancer drug Tamoxifen on blocking estrogen by increasing the levels of a cancer-causing gene called BRAF," said Chin-Yo Lin, one of the researchers at University of Houston in US.
 
The study has appeared in the journal PLOS ONE.
 
Researchers found that alcohol unsuitably promotes sustained expression of BRAF, even in the absence of estrogen, thus increasing effects of estrogen in increasing the risk of breast cancer. 
 
Higher level of the female sex hormone estrogen is connected with greater breast cancer risk.
 
Another study was that alcohol weakened Tamoxifen's ability to suppress the rapid growth of cancer cells.
