Let me know how it turns out. As recently as the s, researchers who tried to figure out why the human body's own immune system didn't attack cancer cells were derided in medical textbooks as believers in witchcraft.
Seriously: Cuba's Cancer Hope shows an example, a useful reminder to those who think that Science [cap S is deliberate] speaks with one immutable and eternal voice are quite daft. The prevailing belief was that T-cells and other warrior elements of the immune system would never attack tumors because they were part of the body itself. The witches—er, researchers—kept chipping at the cancer-as-self theory until scientists in the United States and Japan won a Nobel prize in for showing that two proteins that act as brakes on immune cells were being tricked into action by cancer cells.
If those proteins could be reined in, the conventional wisdom now goes, the human body itself could be a potent weapon against cancer. Cuba's Cancer Hope , with sharply illustrative prose and graphics, gives a lucid account of this part of the story. But when the tale turns to Cuba's development of a lung-cancer vaccine called CIMAvax that enhances the immunological approach with genetic engineering, the show goes off the rails.
Cuba, where the national obsession with cigars has triggered a serious lung cancer problem, began experimenting with the drug in the early s. But it wasn't until President Obama restored U. Customs inspectors, who unless there's an AK in your suitcase, have no way to check what you were doing there. In fact, the only question the show has about anything is, "How is it possible for a county as poor and isolated as Cuba to come up with cutting-edge medicines like this?
According to The Wall Street Journal, Limbaugh once revealed that he started smoking cigarettes when he was a teenager, but quit when he was about 30 years old. Health experts say that smoking is a major risk factor for lung cancer. According to the Centers for Disease Control, smoking is linked to percent of cases of lung cancer. However, the controversial radio host is known to have downplayed the health risks of smoking on his show in the past.
During a broadcast of his show in , Limbaugh responded to a caller who challenged his claim that people should be thankful for the tax money that the government makes from the sale of tobacco products. He also denied claims that secondhand smoke was harmful to health. Regular cigar smokers and cigarette smokers have similar levels of risk for oral cavity and esophageal cancers.
The more you smoke, the greater the risk of disease 3. Unlike nearly all cigarette smokers, most cigar smokers do not inhale. Although cigar smokers have lower rates of lung cancer, coronary heart disease, and lung disease than cigarette smokers, they have higher rates of these diseases than those who do not smoke cigars. All cigar and cigarette smokers, whether or not they inhale, directly expose their lips, mouth, tongue, throat, and larynx to smoke and its toxic and cancer-causing chemicals.
In addition, when saliva containing the chemicals in tobacco smoke is swallowed, the esophagus is exposed to carcinogens. These exposures probably account for the similar oral and esophageal cancer risks seen among cigar smokers and cigarette smokers 3. Even if the smoke is not inhaled, high levels of nicotine the chemical that causes addiction can still be absorbed into the body.
A cigar smoker can get nicotine by two routes: by inhalation into the lungs and by absorption through the lining of the mouth. Either way, the smoker becomes addicted to the nicotine that gets into the body. A single cigar can potentially provide as much nicotine as a pack of cigarettes 1. Because all tobacco products are harmful and cause cancer, the use of these products is strongly discouraged. There is no safe level of tobacco use. People who use any type of tobacco product should be encouraged to quit.
Nicotine replacement products, or nicotine replacement therapy NRT , deliver measured doses of nicotine into the body, which helps to relieve the cravings and withdrawal symptoms often felt by people trying to quit smoking. Strong and consistent evidence shows that NRT can help people quit smoking cigarettes 4. Limited research has been completed to determine the usefulness of NRT for people who smoke cigars. For help with quitting cigar smoking, ask your doctor or pharmacist about NRT, as well as about individual or group counseling, telephone quitlines, or other methods.
