What is pneumonitis?
Treatment-related pneumonitis is a sign of lung injury, when there is inflammation of your lungs. This may be due to chemotherapy, or radiation therapy. It is very similar to pulmonary toxicity.
Pneumonitis commonly occurs 2 to 3 months after radiation to the chest area. It may also develop after chemotherapy that caused lung injury, or lung (pulmonary) toxicity.
Pneumonitis is often diagnosed by chest x-ray, according to the symptoms you are experiencing, and the amount of time after you have completed treatment.
Because you have been diagnosed with pneumonitis, you may develop pulmonary fibrosis. This may occur after a period of 6 to 12 months. You may feel well after your episode of pneumonitis, before the fibrosis occurs.
Some people may develop pulmonary fibrosis after a full dose of radiation to treat their disease, without developing pneumonitis.
