Breath test to identify the type of lung cancer

Researchers have developed a new breath test for diagnosing lung cancer in high risk patients. The test identifies the volatile organic compounds (VOCs) present in the exhaled breath to differentiate between the different types of lung cancer. It is especially useful in differentiating between squamouscell carcinoma and adenocarcinoma of the lungs. The test was presented in this year’s American College of Chest Physicians meeting. Peter Mazzone, from the Cleveland Clinic, along with his...

A biomarker that can be used effectively in diagnosing lung cancers

ca lung idh1
Lung cancer is one of the leading causes of mortality in men. Although several tests have been employed to diagnose lung cancer, most of them have been found to have one or the other drawback. For example, CT imaging, the diagnostic test recommended by most of the physicians to check for lung cancer is non-invasive and highly sensitive, but it lacks specificity. That means it detects many false positive cases too. Scientists have been on a look out of a diagnostic test which is both sensitive...

Novel method of treating lung cancer found

Lung cancer is one of the leading cancers affecting both men and women. As the cancer spreads rapidly to other distant body parts, apart from surgery, chemotherapy also forms an important part of the treatment. But as the drugs used in chemotherapy are generally very toxic, they damage organs and cause multiple side effects when administered intravenously. Now, researchers have developed a novel method of administering these chemotherapy drugs- through inhalation. The method has been described...

Women receiving radiotherapy for breast cancer are more likely to suffer from IHD

Radiotherapy is an important form of treatment for breast cancer in order to prevent recurrences. However, scientists have often wondered the effect of these harmful ionizing radiations on heart. In a new study published in a recent issue of the journal New England Journal of Medicine, the researchers have found that radiation therapy makes the women more prone to suffer from an ischemic heart disease. The risk is the highest within the first five years of receiving the radiotherapy but may...

Annual screening may considerably reduce deaths due to lung cancer

Lung cancer is the number one cause of mortality in American men. In most of these cases, the disease is diagnosed too late for life saving treatment. However, a new study published in the journal Cancer has found that a considerable number of these deaths can be prevented if the people with high risk of developing lung cancer are screened annually. The study, known as the National Lung Screening Trial (NLST), conducted between 2002 and 2009, found that lung cancer mortality can be reduced by...
