Scientists have revealed a simple nose swab could detect the disease. Experts from the Boston University School of Medicine warn smoking damages cells in the linking of the nostrils involved in smell. They found detecting these changes can predict if patients have potentially deadly cancer without having to do biopsies. In the early stages of lung cancer there are usually no signs or symptoms of the disease.
However, when the disease develops, people with the condition can develop symptoms which include a persistent cough, shortness of breath, feeling tired or weak and coughing up phlegm. People who might be sugaring with the disease are given a chest x-ray, but often the scans can’t tell the different between malignant and benign tumours. However, the new study found certain markers in the nose can accurately determine the likelihood of a lung tumour being malignant. READ MORE
