Smoking, cancer, heart disease, and the oral-systemic link: Where we are with research
Source: www.dentistryiq.com Author: Richard H. Nagelberg, DDS Dr. Richard Nagelberg examines the links between smoking, lung cancer, and heart disease, as well as the types of research and studies that established the strength of their credibility over time. Likewise, he considers where we are today with the link between oral health and overall health as he evaluates the current state of oral-systemic research. Perhaps the most universally accepted facts in health care are the detrimental effects of tobacco, particularly cigarette smoking, for nearly every part of the body. It is safe to say that no one disputes the direct causal links between cigarette smoking, lung cancer, and heart disease. Listed below are only two statements regarding the state of this knowledge. ✔️The scientific evidence is incontrovertible: inhaling tobacco smoke, particularly from cigarettes, is deadly. Since the first Surgeon General’s Report in 1964, evidence has linked smoking to diseases of nearly all organs of the body. (surgeongeneral.gov. June 21, 2018) ✔️Smoking is by far the biggest preventable cause of cancer. Thanks to years of research, the links between smoking and cancer are now very clear. Smoking accounts for more than 1 in 4 UK cancer deaths, and 3 in 20 cancer cases. (cancerresearchuk.org) There is a boatload of research supporting this link. However, there has never been one large-scale double-blinded interventional study demonstrating that smoking causes lung cancer and heart disease. The fact that this link exists is based on the cumulative results of numerous smaller studies over a long period [...]
