- Radiation during pregnancy
Prenatal radiation exposure.
- Radiation fibrosis
Scarring of the lungs from radiation. Radiation fibrosis is a consequence of the repair process that follows radiation pneumonitis (inflammation of the lungs due to radiation), as from radiation therapy. Radiation fibrosis typically occurs within months to a few years after the completion of radiation treatments. Whereas the inflammation of radiation pneumonitis is often reversible […]
