Lung Cancer

While this evidence is anecdotal, the idea a dog's super-sensitive nose could detect cancer is not that far-fetched. A 2004 study in the British Medical Journal (BMJ) explained: "Tumours produce volatile organic compounds, which are released into the atmosphere through, for example, breath and sweat. "Some of these volatile organic compounds are likely to have distinctive odours; even when present in minute quantities, they could be detectable by dogs, with their exceptional olfactory acuity." This study was the first to evaluate how well dogs could detect bladder cancer, and found the dogs correctly identified bladder cancer from a urine sample 41 percent of the time.

Melanoma, a type of skin cancer, is often curable when detected and treated in its early stages. However, the disease can rapidly spread to other organs in the body and become deadly. According to the American Cancer Society, more than 7,600 people die of the disease each year in the United States. Thankfully, immune checkpoint inhibitors (ICI), a type of immunotherapy, have transformed the treatment of certain cancers, including melanoma, and improved patient care. But despite the availability of this immunotherapy, doctors have been unable to predict who will benefit from ICI and who will not. Now, a team of researchers at Wake Forest School of Medicine, led by David R. Soto-Pantoja, Ph.D., associate professor of surgery and cancer biology, has discovered blood biomarkers that can potentially predict patient response. Results from the study are published online in Clinical Cancer Research , a journal of the American Association for Cancer Research. "When immunotherapy wo...

Pleural mesothelioma is the most common form of cancer affecting the mesothelium, the protective membrane around your lungs, heart, and abdomen. While rare, this cancer can progress quickly, so it's important to be aware of the symptoms and risk factors. In this article, we explore the symptoms and risk factors for this cancer, as well as how it's diagnosed, staged, and treated. Pleural mesothelioma is a rare type of lung cancer primarily caused by workplace asbestos exposure. It's the most common subtype of mesothelioma, and it affects mesothelial cells within the "pleura" or lining of your lungs, creating malignant tumors. While there are approximately under 3,000 new cases of mesothelioma reported annually in the United States, overall numbers of new patients have been declining over the last 2 decades because of decreased asbestos exposure. But despite the declining number of new cases, pleural mesothelioma is an aggressive cancer that warrants prompt diagnos...

Radiation therapy is a common treatment for lung cancer, but can it cure the disease? There's not a simple yes or no answer. The success rate of radiation depends on the type used, what it is being used for, the stage of the cancer, and much more. In early-stage lung cancer, radiation may be tried as a curative approach, especially in people who are not expected to do well with surgery. While the term "cure" is rarely used, many people will remain cancer free. With cancers that are large or have spread to nearby lymph nodes, radiation may be used to reduce the size of the tumor so that surgery can be done or to destroy any remaining cancer cells after surgery. In advanced disease, radiation is most often used as a palliative treatment—a treatment designed to relieve symptoms and improve quality of life but not as a cure or to extend life.
