Radiation-induced lung injury (RILI) is a general term for damage to the lungs as a result of exposure to ionizing radiation. In general terms, such damage is divided into early inflammatory damage (radiation pneumonitis) and later complications of chronic scarring (radiation fibrosis). Pulmonary radiation injury most commonly occurs as a result of radiation therapy administered to treat cancer. Symptoms and signs The lungs are a radiosensitive organ, and radiation pneumonitis can occur leading to pulmonary insufficiency and death (100% after exposure to 50 gray of radiation), in a few months. Radiation pneumonitis is characterized by: Loss of epithelial cells Edema Inflammation Occlusions airways, air sacs and blood vessels Fibrosis Symptoms of radiation pneumonitis include: fever, cough, chest congestion, shortness of breath, chest pain Diagnosis High resolution CT thorax Treatment “The Canadian Cancer society mentions these things that help to manage radiation, Your healthcare team may recommend medicines to treat radiation pneumonitis, such as: decongestants cough suppressants bronchodilators corticosteroids to reduce inflammation oxygen therapy You can also try the following to help manage symptoms: Rest if you feel short of breath. Drink more fluids and use a cool-air vaporizer or humidifier to keep the air moist. Use an extra pillow to raise your head and upper body while resting or sleeping. Avoid the outdoors on hot, humid days or very cold days (which can irritate the lungs). Wear light, loose-fitting tops and avoid anything tight around the neck, such as ties or shirt collars.“ For more information go to their website, as they have accurate information.“More Info” See also Radiation poisoning References Further reading External links PubMed Radiation health effects Radiation therapy Lung diseases due to external agents
