Researchers at Thomas Jefferson University in the USA report that nicotine absorbed from smoking is significantly associated with a type of cancer called PDA, or pancreatic ductal cancer.
Nicotine appears to promote the expression of a protein that causes pancreatic ductal cancer to become metastatic and quickly fatal. Thank you researchers at Thomas Jefferson University for yet one more scientific truth about the deadly affect of smoking. We pray that humanity awakens to these facts so that the substance
of tobacco soon vanishes into a forgotten history.
