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
Radiation, used to treat cancer, can cause pneumonitis when applied to the chest or full body. [16] Radiation pneumonitis occurs in approximately 30% of advanced lung cancer patients treated with radiation therapy. [16] Aspiration pneumonitis is caused by a chemical inhalation of harmful gastric contents which include causes such as:
The lungs are the most 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: [10] Loss of epithelial cells; Edema; Inflammation; Occlusions of airways, air sacs and blood vessels; Fibrosis
Side effects on the lungs can be very varied, and can include signs and symptoms that are either clinical, or radiological (i.e., seen on chest X-ray or CT), or both.They can include lung inflammation (pneumonitis), secondary (in this context, indirectly caused) lung infection (), lung fibrosis, organising pneumonia (bronchiolitis obliterans organising pneumonia, BOOP), ARDS (acute respiratory ...
ARS involves a total dose of greater than 0.7 Gy (70 rad), that generally occurs from a source outside the body, delivered within a few minutes. [1] Sources of such radiation can occur accidentally or intentionally. [6] They may involve nuclear reactors, cyclotrons, certain devices used in cancer therapy, nuclear weapons, or radiological ...
Current treatments include surgery, chemotherapy, radiation and targeted therapy for those who have a cancer with a biomarker. Doctors have good success in treating early-stage lung cancer, so ...
Radiation fibrosis, usually from the radiation given for cancer treatment. Certain drugs such as amiodarone, bleomycin and methotrexate. As a consequence of another disease such as rheumatoid arthritis. Hypersensitivity pneumonitis due to an allergic reaction to inhaled particles.
