E-cigarettes are as bad as cigarettes, flavouring can impair lung function

E-cigarettes are as bad as cigarettes, flavouring can impair lung function

For smokers looking to quit smoking, e-cigarettes often seem to be a viable alternative. But there are many disadvantages to e-cigarettes, and many studies raise doubts about its safety. A new study done by the University of North Carolina in the US shows that a common e-cigarette flavouring has toxic chemicals similar to those found in tobacco smoke. The chemicals can even disrupt the lungs’ antibacterial defense system, the study has found. Previous studies have shown that while people who use e-cigarettes smoke less and are more likely to quit smoking,…

40% women lung cancer patients in Goa non-smokers, likely victims of passive smoking

40% women lung cancer patients in Goa non-smokers, likely victims of passive smoking

Almost 40% of women in Goa who have lung cancer do not smoke themselves, which means it is likely that they are victims of `passive smoking’, an anti-tobacco NGO has said. The National Organisation for Tobacco Eradication (NOTE) said yesterday that there has been a rise in the number of women in the state who smoke. The overall percentage of smokers in the state’s population has dwindled in the last three decades, it said. NOTE India president Dr Shekhar Salkar told reporters that almost 40% of the women diagnosed with…

Don’t ignore oral hygiene. Severe gum disease linked to lung, colon cancers

Don’t ignore oral hygiene. Severe gum disease linked to lung, colon cancers

Do you have bad oral health? Beware, you may be at high risk of developing cancers of lung, colon and pancreas, researchers have warned. Advanced gum disease, also called periodontitis, is caused by bacterial infection that damages the soft tissue and bone that supports the teeth. The findings, led by researchers from the Tufts University in the US, showed that participants who were edentulous or lacking teeth – a sign of severe periodontitis – had an 80% increase in risk of developing colon cancer. Periodontitis is also linked with pancreatic…

Cold Weather, Smog Could Lead to Rise in Heart, lung Cases

Cold Weather, Smog Could Lead to Rise in Heart, lung Cases

The week following Diwali has seen Delhi and the National Capital Region shrouded in a blanket of smog that has made breathing difficult and led to a rise in heart and lung complaints. With the situation unlikely to change for a few more days and the nippy winter already knocking at the doors, cardiologists and pulmonologists have warned that prolonged exposure to the highly toxic air can cause cardiac arrest and lung complications. Noting that cardiovascular disease (CVD), over the past decade, has emerged as the single most important cause…

Smoking a pack a day causes 150 mutations in every lung cell, research shows

Smoking a pack a day causes 150 mutations in every lung cell, research shows (Getty Images) Scientists have found that smoking a pack a day of cigarettes can cause 150 damaging changes to a smoker’s lung cells each year. The findings come from a study of the devastating genetic damage, or mutations, caused by smoking in various organs in the body. Publishing in the journal Science on Thursday, the researchers said the findings show a direct link between the number of cigarettes smoked in a lifetime and the number of…

Smoking a Pack a Day Causes 150 Mutations in Every Lung Cell

Scientists have found that smoking a pack a day of cigarettes can cause 150 damaging changes to a smoker’s lung cells each year. The findings come from a study of the devastating genetic damage, or mutations, caused by smoking in various organs in the body. Publishing in the journal Science on Thursday, the researchers said the findings show a direct link between the number of cigarettes smoked in a lifetime and the number of mutations in the DNA of cancerous tumors. The highest mutation rates were seen in lung cancers,…

Exercise May Help Patients with Lung Disease

Exercise May Help Patients with Lung Disease

Increased physical activity among patients with a type of lung disease could reduce their risk of anxiety as well as depression, a study has found. Chronic obstructive pulmonary disease (COPD) is a group of lung diseases that block airflow and make it difficult to breathe. The prevalence of depression and anxiety is approximately 40 per cent in COPD patients while the corresponding figure is less than 10 per cent in the general population, the study said. But, the results suggested that in patients with COPD, higher levels of physical activity could lessen…

Air Pollution Tied to Shorter Survival With Lung Cancer

Air Pollution Tied to Shorter Survival With Lung Cancer

Exposure to air pollution has long been associated with an increased risk of lung cancer, and a new study suggests it might also be tied to a faster death from the disease. Researchers examined cancer registry data on more than 350,000 people diagnosed with lung cancer in California and found patients who lived in communities with higher than average levels of air pollution typically died sooner than their peers who lived in places with cleaner air. Patients with lung cancer may be a new subgroup of people susceptible to the…

Air pollution reduces life span of lung cancer patients

Air pollution reduces life span of lung cancer patients

Air pollution reduces life span of lung cancer patients (Getty Images) A population-based study has suggested air pollution is deadly for the patients with lung cancer, as it shortens their survival span. The finding shows that the trends were most noticeable for early stage disease, particularly adenocarcinoma, the most common type of non-small cell lung cancer, which accounts for 80 percent of lung cancer cases. Air pollution has been linked to a higher incidence of lung cancer and death, but little is known about its potential impact on an individual’s…

New lung cancer find paves way for better therapies

A team of researchers has successfully inhibited tumour growth in a new subtype of lung cancer. (Getty Images) A team of researchers has successfully inhibited tumour growth in a new subtype of lung cancer. Adenocarcinomas, a non-small cell lung cancer (NSCLC), account for about 40 percent of cancer diagnoses, but few treatments are available for the disease. The team led by Elena Levantini of Beth Israel Deaconess Medical Center (BIDMC) identified a subtype of human adenocarcinoma. The research could help determine which individuals are at greatest risk of developing lung…
