A definitive link between nicotine intake and breast cancer has been identified by researchers at Taipei Medical University, according to an article in the latest edition of the Journal of the National Cancer Institute.
Smoking has previously been linked specifically to lung cancer and throat cancers, whereas a link between breast cancer and nicotine intake had not been identified.
The study noted that it was nicotine in particular that had a encouraged the growth of cancer producing cells. Breast cancer tumors were found to be particularly susceptible to nicotine, with nicotine attaching to the receptor cells of tumors.
Researchers noted that it was in particular nicotine and not other carcinogenic substances found in cigarettes that triggered breast cancer growth opening questions about the impact of nicotine replacement therapy for people trying to quit smoking.
