A Lesson from Lung Cancer and the Cigarette Industry 1940 to 1970: The Human Devastation and Societal Costs of Commercially-Motivated Anti-Science Denials

Figure 16.1b The Biology of Cancer (© Garland Science 2007) Lung cancer in males after 1985

Some Chilling Calculations: Lung Cancer Death Rate in Men at Peak Year (1990): 90 per 100,000 or about 1 per 1,000 men Number of Men in the US in 1990: About 150 Million Deaths of Men from Lung Cancer in 1990: 150,000 Clear Demonstration of Tobacco-induced Lung Cancer: ~1940 Action to curb advertising and to control tobacco epidemic: ~1970 Time required to reverse the rising death-rate: ~ 30 Years Number of Men Killed by the 30-Year Delay: ~4,500,000 Number of Women killed by the Same Delay: ~2,000,000

The Messages from the History of Cigarettes and the Human Devastation They Caused: 1.Evidence-based Science and Medicine: Denial of evidence does not change the facts. Nature doesn’t care what we believe or how much we stand to gain economically. If we deny the evidence, the consequences can be horrendous. 2. The Response to Corrective Action The time-delay between accepting the evidence, orchestrating a response, and gaining control of the problem (if control is still possible) can be decades. The devastation during that time delay can be monumental.

In 1990 we saw the full impact of the failure to respond to the evidence of cigarettes and lung cancer. Lung cancer incidence and deaths in both men and women began to drop. In 2040 will we see the impact of failing to respond to greenhouse gases and global climate change in 2013? Will effective response still be possible in 2015 or 2030?

Please clear desks for Turning Point Questions No devices other than the NXT Transmitter are allowed. If each person can move along sending in their answers it reduces the opportunity for any one to cheat. The first three slides are multiple choice so they shouldn’t take much time.

When you get the clear screen for sending in your responses with the NXT transmitter, please respond to this multiple choice question: Throughout the 20 th Century there was a stunning 15-fold increase in ___________ cancer. (two more multiple-choice questions follow) 1.Pancreatic 2.Breast 3.Stomach 4.Liver 5.Lung 6.Colorectal 7.Virtually every cancer 8.No single cancer

Throughout the 20 th Century there was a remarkable and initially unexplained major decrease in ___________ cancer. 1.Pancreatic 2.Breast 3.Stomach 4.Liver 5.Lung 6.Colorectal 7.Virtually every cancer 8.No single cancer

The major decrease in this cancer was eventually traced to a decline in a major causative source for this disease. This source was found to be ___________________ 1.An infectious bacterium 2.Chemical carcinogens in the diet 3.Over-nutrition 4.A virus 5.Mercury poisoning 6.Poor refrigeration

Fill-in-the Blank Question 3% of cancers diagnosed in men or women in the United States are Pancreatic cancers. 6% of Cancer Deaths in the U.S. are caused by Pancreatic cancer. How can that be? What does that mean about pancreatic cancers?

This graph shows a change in the pattern of prostate cancer beginning around Why did that happen?

Note the terrifying increase in deaths from lung cancer:1930 to Why was that happening? What could be done about it? Can we change the trajectory of that curve?

Cx Types Note Stunning drop in deaths from stomach cancer: 1930 to 1985 What could possibly be the cause of this dramatic and very favorable event? Why did uterine cancer death rate go down in the 1950’s? Can we apply the lessons from stomach and uterine cancers to other cancers?
