Dry January might help reduce your risk of cancer

Source: www.iflscience.com Author: Holly Large, Editorial Assistant If one of your New Year’s resolutions happens to be staying sober, scientists at the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) have some good news for you: not drinking alcohol, or even just cutting back on the bevs, can reduce your risk of some cancers. There’s already evidence to suggest that alcohol consumption can increase the risk of some cancers; according to WHO estimates, more than 740,000 global cancer cases in 2020 were caused by alcohol use. But as report author Farhad Islami told STAT News, “[W]e wanted to know, what if people stop drinking?” Islami was part of a group of 15 scientists investigating the impact of reducing or ceasing alcohol intake on cancer risk, reviewing over 90 published studies over the course of four months. From this data, the team discovered that there was sufficient evidence to suggest that cutting back on alcohol could be linked to a reduced risk of oral and oesophageal cancers. There was also limited evidence of a reduction in risk for laryngeal, colorectal, and breast cancers. One of the key contributors to risk, the researchers found, was a toxin called acetaldehyde. Also known as ethanal, acetaldehyde is produced by the breakdown of alcohol in the liver. It plays a role in nasty hangovers and, as the studies suggested, increases someone’s risk of cancer. Drinking less alcohol reduces exposure to such a carcinogen and thus, the risks that come with it. In [...]

Alcohol should have cancer warning labels, say doctors and researchers pushing to raise awareness of risk

Source: www.cbc.ca Author: Ioanna Roumeliotis & Brenda Witmer · CBC News It's not a secret, but it may as well be. Few Canadians know the truth, and few may want to hear it: alcohol, any amount of alcohol, can cause cancer. There is no safe amount, and the calls to inform Canadians are growing. "Even drinking one drink a day increases your risk of some cancers — including, if you're a woman, breast cancer — but also cancers of the digestive system, the mouth, stomach," said Tim Stockwell, a senior scientist with the Canadian Institute for Substance Use Research at the University of Victoria. "The risk increases with every drink you take." Alcohol has been classified as a Group 1 carcinogen (carcinogenic to humans) for decades by the International Agency for Research on Cancer (IARC). It's right up there with tobacco and asbestos. Alcohol is also a top cause of preventable cancer after smoking and obesity. But the vast majority of Canadians have no idea of the risk. Stockwell wants to change that, and he and other health experts are advocating for cancer warning labels on alcohol containers. People need to know, he says, that though there are other genetic and lifestyle factors that contribute to developing cancer, every drink comes with a risk. "The risk from alcohol, it's a dose response. The bigger and more frequent the dose, the higher your risk." Kathy Andrews had no idea that the wine she enjoyed most nights before she got pregnant was [...]

Asia’s deadly secret: the scourge of the betel nut

Source: www.bbc.com Author: staff It is used by almost a tenth of the world's population. It gives people a buzz equivalent to six cups of coffee and is used variously as a symbol of love, marriage and a cure for indigestion and impotence. But it is also leading tens of thousands to an early grave. The culprit? The humble betel nut. Found across Asia, these nuts are harvested from the Areca palm and are chewed for their warming glow and stimulating properties. Such is its effectiveness, that alongside nicotine, alcohol and caffeine, betel nuts are believed to be one of the most popular mind-altering substances in the world. Although used by women and children, the nuts are especially popular among working-age men, who chew to stay awake through long hours of driving, fishing or working on construction sites. But the short-lived benefits come at a terrible cost. High rates of oral cancer are destroying the lives of many who buy betel nuts, often decades after their first taste. Now in Taiwan, where the nuts are affectionately known as 'Taiwan's chewing gum', the government is taking action to curb this centuries-old habit and reduce the thousands of lives lost each year. Dangerous combination Regular betel nut chewers stand out from the crowd with their red-stained lips and teeth The betel nut is a key part of many Asian cultures and can be consumed dried, fresh or wrapped up in a package known as a quid. Although the exact preparation [...]

Red wine: Cancer causing or cancer protective? Researchers say both

Source: Medical News Today Author: David McNamee People who drink red wine have the lowest incidence of cancer caused by alcohol, and researchers think they know why that is. A new study published in the medical journal Advances in Experimental Medicine and Biology explains that while alcohol has cancer causing effects, red wine offers an anti-cancer quality that most other forms of alcohol do not offer. The study was completed by researchers at the University of Colorado Cancer Center. When people first begin to metabolize alcohol, it is converted to acetyl aldehyde, a known carcinogen. “With enough alcohol, the body can get behind and end up with a backlog of acetyl aldehyde,” Dr. Robert Sclafani, the author of the paper, said. As he looked at epidemiological studies of head and neck cancer, he noted that alcohol is a major factor. He explained that when he separated the data into the type of alcohol, it was clear that people who drank red wine seemed to be more protected from cancer. “In red wine, there’s something that’s blocking the cancer-causing effect of alcohol,” Sclafani said. Sclafani believed the resveratrol found in the skin of the grapes used to make red wine removes the most damaged cells from wine drinkers’ bodies. The most heavily damaged cells are also the cells most likely to turn cancerous, according to Medical News Today. “Alcohol bombards your genes,” Sclafani explained. “Your body has ways to repair this damage, but with enough alcohol eventually some damage isn’t fixed.

Hookah smoke increases benzene exposure, risk for leukemia

Source: www.medicalnewstoday.com Author: staff Tobacco use is the leading preventable cause of mortality worldwide and is responsible for the deaths of 6 million people annually. Hookah smoking, a form of tobacco use that employs a partially filled water jar, has come under scrutiny in a new study, which suggests hookah smokers and non-smokers exposed to the smoke have increased uptake of benzene, a substance linked to increased risk of leukemia. Hookah smokers The study is published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. According to the researchers - led by Nada Kassem, associate director at the Center for Behavioral Epidemiology and Community Health at San Diego State University in California - the World Health Organization (WHO) and the US National Toxicology Program have classified benzene as a Group 1 carcinogen. WHO further report that benzene is carcinogenic to humans, recommending that there is no safe level of exposure. Hookah smoke, however, is a source of benzene exposure and is, therefore, a risk factor for leukemia. The most popular kind of hookah tobacco is known as Moassel, which is sweetened and flavored tobacco that contains about 30% tobacco fermented with molasses and fruits mixed with glycerin and chemical flavors. Kassem and her colleagues note that in the US in 2013, it was reported that 26.6% of male and 23.2% of female college students have used hookah at some point in time. Alarmingly, 8.1% of male and 6.6% of female middle and high school [...]

Researchers find way to diagnose aggressiveness of oral cancer

Source: www.news-medical.net Author: staff Studying mouth cancer in mice, researchers have found a way to predict the aggressiveness of similar tumors in people, an early step toward a diagnostic test that could guide treatment, according to researchers at Washington University School of Medicine in St. Louis. "All patients with advanced head and neck cancer get similar treatments," said Ravindra Uppaluri, MD, PhD, associate professor of otolaryngology. "We have patients who do well on standard combinations of surgery, radiation and chemotherapy, and patients who don't do so well. We're interested in finding out why." Reporting in Clinical Cancer ResearchK/em>, the investigators found a consistent pattern of gene expression associated with tumor spreading in mice. Analyzing genetic data from human oral cancer samples, they also found this gene signature in people with aggressive metastatic tumors. "We didn't automatically assume this mouse model would be relevant to human oral cancer," said Uppaluri, who performs head and neck surgeries at Barnes-Jewish Hospital. "But it turns out to be highly reflective of the disease in people." Rather than use genetic methods to induce tumors in the mice, the research team repeatedly applied a known carcinogen, in much the same way humans develop cancer of the mouth. "Patients often have a history of tobacco and alcohol use, which drive the development of these tumors," Uppaluri said. "We felt that exposing the mice to a carcinogen would be more likely to produce similar kinds of tumors." The researchers, including first author Michael D. Onken, PhD, research assistant [...]

Smoking on waking increase cancer risk

Source: timesofindia.indiatimes.com Author: Malathy Iyer It is well known that smoking is injurious to health, but what is now emerging is that smokers who light up first thing in the morning are more likely than other smokers to suffer from lung or oral cancer. The research could serve as an eye-opener for India, where tobacco-related cancers claim over 1 million lives every year. The correlation between the time of the first smoke and cancer comes from a carcinogen found in cigarettes. A new study from Penn University in the US has shown that smokers who consume cigarettes immediately after waking up have higher levels of a carcinogen called NNAL (a derivative of NNK (4-(methylnitrosamino)-1-[3-pyridyl]-1-butanone) throughout the day in comparison to others. Steven Branstetter, assistant professor at Penn University, said that other researches had shown that NNK induces lung tumors in several rodent species. His team hence believes that levels of NNAL in the blood can predict lung cancer risk in rodents as well as in humans. The team examined data on 1,945 smoking adults and found that around 32 % smoked their first cigarette of the day within 5 minutes of waking; 31 % smoked within 6 to 30 minutes of waking; 18 % smoked within 31 to 60 minutes of waking; and 19 percent smoked more than one hour after waking. "Most importantly, we found that NNAL level was highest among people who smoked the soonest upon waking, regardless of the frequency of smoking and other factors that predict [...]

Alcohol consumption ups oral cancer risk in men

Source: www.drbicuspid.com/ Author: Donna Domino, Features Editor Alcohol consumption causes approximately 20,000 cancer deaths in the U.S. annually, especially oral cavity cancer in men and breast cancer in women, according to a new study in the American Journal of Public Health (February 14, 2013). It is the first comprehensive analysis of alcohol-attributable cancer deaths in the U.S. in more than 30 years, the study authors noted. Notably, even moderate drinkers who consume 1.5 drinks daily or fewer accounted for 30% of alcohol-caused cancer deaths, according to researchers from the Boston University School of Medicine and the School of Public Health. Cancers of the mouth, throat, and esophagus were common causes of alcohol-related cancer deaths among men, resulting in a total of about 6,000 annual deaths, they noted. Breast cancer was the most common cause of alcohol-caused cancer deaths in women, resulting in about 6,000 deaths annually, or about 15% of all breast cancer mortality. In addition, alcohol was cited as a prominent cause in the premature loss of life, resulting in the loss of about 18 years among people who died of cancers attributed to alcohol, the study found. Previous research consistently shows that alcohol increases the risk for cancers of the oral cavity and pharynx, larynx, esophagus, and liver. And recent studies show that alcohol also increases the risk of cancers of the colon, rectum, and women's breasts. While estimates have shown that alcohol accounts for about 4% of all cancer-related deaths worldwide, there is a lack of attention [...]

DNA adducts linked to oral cancer in smokers

Source: www.news-medical.net Author: Sarah Guy, medwireNews Reporter Having a high susceptibility to certain types of DNA damage caused by tobacco smoking could significantly increase the risk for oral cancer, show results of a Taiwanese study. Levels of BaP 7,8-diol 9,10-epoxide (BPDE) - a metabolite of Benzo[a]pyrene, an important carcinogen found in cigarette smoke - correlated positively with smoking status in a cohort of individuals with oral cancer, report the researchers. The findings also indicate a significantly increased risk for oral cancer among individuals with high DNA adduct levels compared with their peers with low levels. "Based on our finding, we suggest that detected BPDE-like DNA adducts could be used as a biomarker for oral cancer risk," write Huei Lee (Taipei Medical University) and colleagues in the Archives of Oral Biology. The team analyzed BPDE-DNA adduct levels in oral tissue samples from 158 oral cancer patients and 64 individuals without cancer (controls), using immunohistochemistry and enzyme-linked immunosorbent assay (ELISA). The results of these assays significantly and positively correlated , so that immunohistochemistry-negative patients did not have detectable DNA adduct levels using ELISA and vice versa. DNA adduct levels also positively correlated with smoking status among the cancer patients, note the researchers, with significantly higher adduct levels among smokers than nonsmokers, at 93.18 versus 0.04 adducts per 108 nucleotides. Lee and co-workers also observed that cancer patients had significantly higher DNA adduct levels than controls, at a range of 0-358.00 versus 0-39.50 adducts per 108 nucleotides. Indeed, DNA adduct level was an [...]
