Some women will think twice before lighting their cigarette. A study published Wednesday, October 15 revealed that the nicotine absorbed by the organism played a role in the development and spread of breast cancer.
We suspected the relationship between these two elements but nothing proved scientifically and officially the toxicity of this combination. This study was conducted by researchers at Beth Israel Deaconess Medical Center and published in the newspaper Cancer Research of the American Association for Research on theCancer.
This is the first study to assess the effects of nicotine on the appearance of cancerous tumors of the breast.
The principal researcher who studied the link between nicotine and breast cells is Chang Yan Chen. Dr. Chen and his team discovered that some epithelial breast cells (MCF10A) and some cancer cells (MCF7) have several elements of nAChR, a receptor for nicotine. Once in contact, these elements initiate a process that increases the size and migration of the cells.
"We have seen that breast cells have different elements of nAChR and that the nicotine acts on the size of tumors in mammary cells prone to Cancer or the cells of CancerDr. Chen says, "In vitro and in vivo studies have shown that no metastasis occurs with the administration of nicotine alone. Right now all we can suggest is that the nicotine affects the process of size ".
