Lung cancer signs even in "healthy" smokers

Published October 2013 — Smokers who have been given a clean bill of health from their doctors after normal examination results may still have early signs of lung cancer, according to a study published in the journal, Stem Cells. 

Dr. Robert Crystal, chairman and professor of genetic medicine at Weill Cornell Medical College states, "Cells that are lining the airways in smokers are in a more primitive state and have some of the features that you see in lung cancers. So, basically, the guy smoking outside the building who thinks he is normal is already on his way to developing lung cancer."

Dr. Crystal says that occasional smokers and passive smokers are also at risk. "With any smoke you are exposed to, your airways cells are being programed in an abnormal fashion."

Quitting smoking is always worthwhile and lung cancer is not inevitable. According to the U.S. National Cancer Institute smokers who quit at about age 30 "reduce their chance of dying prematurely from smoking-related diseases by more than 90 percent."

Smoking and Bone Loss

Published July 2013 — Recent studies show a direct relationship between tobacco use and decreased bone density. Smoking is one of many factors—including weight, alcohol consumption, and activity level—that increase the risk for osteoporosis, a condition in which bones weaken and become more likely to fracture.

Significant bone loss has been found in older women and men who smoke. Quitting smoking appears to reduce the risk for low bone mass and fractures. However, it may take several years to lower a former smoker's risk.

In addition, smoking from an early age puts women at even higher risk for osteoporosis. Smoking lowers the level of estrogen in the body, which can cause one to go through menopause earlier, boosting the risk for osteoporosis.

Cigarettes and Cancer

Published February 2013 — Cigarette smoking kills an estimated 440,000 U.S. citizens each year—more than alcohol, illegal drug use, homicide, suicide, car accidents, and AIDS combined. Between 1964 and 2004, more than 12 million Americans died prematurely from smoking, and another 25 million U.S. smokers alive today will most likely die of a smoking-related illness.

Cigarette smoking accounts for about one-third of all cancer deaths. The overall rates of death from cancer are twice as high among smokers as nonsmokers, with heavy smokers having rates that are four times greater than those of nonsmokers. Foremost among the cancers caused by tobacco use is lung cancer—cigarette smoking has been linked to about 90 percent of all cases of lung cancer, the number one cancer killer of both men and women. Smoking is also associated with cancers of the mouth, pharynx, larynx, esophagus, stomach, pancreas, cervix, kidney, bladder, and acute myeloid leukemia.

Secondhand Smoke Costs Rise Sharply

Published February 2012 — An Indiana University study released January 9, 2012, found that the economic costs of secondhand smoke in the state are more than $1 billion a year—triple a previous estimate.

The study, conducted by the Bowen Research Center at the Indiana University School of Medicine, calculated that in 2010, each Hoosier paid $201 because of the cost of secondhand smoke. That comes to $1.3 billion a year­‑—about $327.1 million in direct healthcare costs and $977.5 million from premature loss of life.

Secondhand smoke increases an individual's risk of heart disease, lung cancer, respiratory illness and many other diseases. Nationally, it is estimated that more than half of all children ages 3 to 11 live in homes where they are exposed to secondhand smoke.

What's in a Cigarette?

Published October 2011 — There are approximately 600 ingredients in cigarettes. When burned, they create more than 4,000 chemicals. At least 50 of these chemicals are known to cause cancer, and many are poisonous. 

Many of these chemicals are also found in consumer products, but these products have warning labels. While the public is warned about the danger of the poisons in these products, there is no such warning for the toxins in tobacco smoke.

Here are a few of the chemicals in tobacco smoke, and other places they are found:

Smoking and Cancer

Published August 2011 — Smoking harms nearly every organ of the body. Smoking causes many diseases such as cancer and reduces the health of smokers in general. While it is true that more people die from lung cancer than any other type of cancer, smoking also causes the following cancers which account for a large number of deaths.

Even Brief Exposure is Harmful

Published May 2011 — The 30th Surgeon General Report on tobacco-related issues was released in December 2010. This new report details the serious health effects of even brief exposure to tobacco smoke. It concludes that:

Economic Benefits of Smoking Cessation

Published October 2010 — Smoking costs Indiana more than $7 billion dollars every year. This, according to a new study conducted by researchers at Penn State University and released by the American Lung Association, is money that the state and consumers could be spending in other places. The study determined that smoking cessation programs are less costly to the public than not helping smokers who want to quit, and calculates that Indiana can save an average of nearly $15 million dollars annually by doing so.

Parents: Help Keep Kids Tobacco-Free

Published July 2010 — Prevalence of cigarette use among children and teens in the U.S. is less than it was ten years ago but it is still higher than that of adults. Parents are the key in preventing a child’s tobacco use. Parents must take the lead not just once or occasionally, but in the context of a series of conversations that take place as a child learns and grows. Start the dialog about tobacco at age 5 or 6 and continue through the high school years. Many kids start using tobacco by age 11, and many are addicted by age 14.

Kids who use tobacco:

Despite the impact of movies, music, and TV, parents can be the greatest influence in their kids’ lives.

Quitting Tobacco is Now More Possible than Ever

Published March 2010 — Research reviewed for the National Library of Medicine guideline, Treating Tobacco Use and Dependence: 2008 Update, suggests a bright future for treating tobacco dependence. Effective treatments exist that can significantly increase rates of long-term abstinence, and such treatments are effective across a broad range of populations. 

Free & Clear® Quit For Life™ Program 
IU’s medical benefits cover the cost of a tobacco cessation plan with Free & Clear, Inc. Quit for Life program. The benefit is available to all full-time Academic and Staff employees and their family members 18 or older. The plan is fully paid for by the University.

Body Shape

Published August 2009 — The effect of smoking on the endocrine system (glands which secrete hormones) causes smokers to store even normal amounts of body fat in an abnormal distribution. Smokers are more likely to store fat around the waist and upper torso, rather than around the hips. This means smokers are more likely to have a higher waist-to-hip ratio (WHR) than non-smokers. A high WHR is associated with a much higher risk of developing diabetes, heart disease, high blood pressure, gallbladder problems and (in women) cancer of the womb and breast. A study of American men also found a dose-response relationship between the number of cigarettes smoked and waist-to-hip ratio. 

However, changes to WHR induced by smoking need not be permanent. The results of a Swedish study suggests that while some weight gain after stopping smoking can be expected, it is less of a health risk because it is not deposited in the upper torso, where it is associated with increased risk of heart disease.
