A new study shows that young women who smoke may be more likely to develop breast cancer.

The study found that women between 20 and 44 years old who had also smoked one pack per day or more for 10 years were more likely to develop estrogen receptor-positive breast cancer.  The women of this category were not found to be more likely to develop triple-negative breast cancer.

“I think there is a growing appreciation that breast cancer is not just one disease and there are many different subtypes.  In this study, we were able to look at the different molecular subtypes and how smoking affects them,” states Dr. Li.

Dr. Li conducted his study on information from women who were diagnosed with breast cancer between 2004 and 2010 in the Greater Seattle area.  It was found that 778 were diagnosed with estrogen receptor-positive breast cancer, and 182 were diagnosed with triple-negative breast cancer.  In addition, information from 938 cancer-free women was included as well.

The study found that women who had ever smoked were 30 percent more likely to develop any type of breast cancer.  In addition, women who were recent or current smokers who had smoked for at least 15 years were 50 percent more likely to have estrogen receptor-positive breast cancer.  Those that smoked one pack per day or more were 60 percent more likely to have estrogen receptor-positive breast cancer.

“There are so many different chemicals in cigarette smoke that can have so many kinds of effects,” states Dr. Li.

“I think that there is growing evidence that breast cancer is another health hazard associated with smoking,” states Dr. Christopher Li, the study’s lead author.  His study was published in the journal Cancer.

    Everyone knows that smoking causes cancer. Even the government admits to it but still endorses tobacco products despite that the public health authorities are supposed “to protect you.” Dream on. What the public generally does not know is that medical x-rays are the prime cause of breast cancer (read “The Mammogram Myth” by Rolf Hefti). But because corporate profits of the medical industry are on the line this data has been conveniently overlooked and ignored…
