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

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

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 (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…

middle aged human beings more likely to be diagnosed with Lung cancer

center-elderly sufferers among ages 50 to 64 are much more likely to be diagnosed with late level lung cancer than older sufferers, says a have a look at done with the aid of most cancers research uk, a cancer charity.”Our outcomes display that younger patients in their 50s and early 60s are much more likely to be diagnosed with advanced lung most cancers in comparison to patients in older age corporations,” said David Kennedy, facts and studies analyst. “in addition analysis will cognizance on know-how this relationship to look if…
