Nicotine found to spur breast cancer growth
NEW YORK - Nicotine, whether absorbed by smoking cigarettes or inhaling second-hand smoke, may promote tumor growth and the spread of breast cancer, a study found.
Nicotine made breast cancer cells more likely to multiply and migrate in laboratory tests, according to the study published in yesterday’s issue of the journal Cancer Research. Such evidence also suggests that nicotine given to help people stop smoking should be used cautiously.
