More negative effects of smoking on the body are specialists. It was found that breast cancer cells are sensitive to nicotine. It has long been known that nicotine affects the outcome of disease, such as lung, larynx, oral cavity and other organs. But there remains little studied the effect of nicotine on breast cancer, especially in tumor development and metastasis. Scientists from New York decided to investigate the matter further and conducted a study that examined the negative effects of nicotine on breast cancer cells. Specialists are found in both normal and cancer cells from several types of specific receptors of nicotine, such as those that exist in the cells of the nervous system. According to experts, the role of these receptors is not exactly known, but researchers suspect that nicotine molecule bound to the receptor and stimulate the proliferation of cancer cells. Experts managed to prove this theory in an experiment on mice. The authors of the study found that nicotine itself is not the cause of breast cancer, but in combination with other factors provoking disease promotes more intensive growth and spread of cancer cells.
