Nicotine in cigarettes linked to breast cancer for the first time

The substance that makes cigarettes addictive may also cause the growth of cancer tumours, scientists revealed today.
It is the first time nicotine has been implicated as one of the chemicals in cigarettes that can trigger the development of breast cancer.
The findings, published in The Journal of the National Cancer Institute, could be a major blow to makers of nicotine-based products that help smokers to quit.
A customer uses an electronic cigarette that contains just nicotine and water. It has been promoted as a 'healthy alternative' but now scientists have linked nicotine to breast cancer

Normal cigarettes are known to contain at least 60 cancer-causing substances including carbon monoxide, tar and arsenic, but until now nicotine had not been on the list.
Researchers from Taipei Medical University looked looked at both breast cancer cells and normal cells to see if nicotine promoted tumour growth at a cellular level.
Dr Yuan-Soon Ho and his team found that when normal cells were treated with nicotine in the laboratory it promoted the development of cancer characteristics. Likewise reducing the level of nicotine inhibited tumour growth.
The research could have a negative impact on companies that make nicotine gum, patches and electronic cigarettes that are promoted as a 'healthy alternative' for smokers.
The authors said their study was limited by its small sample size, which looked at just a few hundred Asian patients and further study was needed.
In an accompanying editorial Dr Ilona Linnoila of the Center for Cancer Research at the National Cancer Institute, said: 'The study suggests not only that smoking could be causally related to breast carcinogenesis but also that nicotine could directly contribute to the molecular mechanism of carcinogenesis in addition to indirectly contributing by promoting addiction to smoking.'
She added: 'Better understanding of the molecular mechanisms of the cholinergic pathways will lead to more opportunities for intervention and prevention of tobacco toxicity.'

WARNING FROM RAEL: For those who don't use their intelligence at its full capacity, the label "selected by RAEL" on some articles does not mean that I agree with their content or support it. "Selected by RAEL" means that I believe it is important for the people of this planet to know about what people think or do, even when what they think or do is completely stupid and against our philosophy. When I selected articles in the past about stupid Christian fundamentalists in America praying for rain, I am sure no Rael-Science reader was stupid enough to believe that I was supporting praying to change the weather. So, when I select articles which are in favor of drugs, anti-semitic, anti-Jewish, racist, revisionist, or inciting hatred against any group or religion, or any other stupid article, it does not mean that I support them. It just means that it is important for all human beings to know about them. Common sense, which is usually very good among our readers, is good enough to understand that. When, like in the recent articles on drug decriminalization, it is necessary to make it clearer, I add a comment, which in this case was very clear: I support decriminalizing all drugs, as it is stupid to throw depressed and sad people (as only depressed and sad people use drugs) in prison and ruin their life with a criminal record. That does not mean that there is any change to the Message which says clearly that we must not use any drug except for medical purposes. The same applies to the freedom of expression which must be absolute. That does not mean again of course that I agree with anti-Jews, antisemites, racists of any kind or anti-Raelians. But by knowing your enemies or the enemies of your values, you are better equipped to fight them. With love and respect of course, and with the wonderful sentence of the French philosopher Voltaire in mind: "I disapprove of what you say, but I will defend to the death your right to say it".
"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
There is nothing glorious about what our ancestors call history,
it is simply a succession of mistakes, intolerances and violations.
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
