In some cases, the symptoms of BOOP may resolve without treatment especially the post breast radiation-type. In some mild cases such as individuals without symptoms or who have non-progressive disease, the process can be monitored and treated later if necessary. Most individuals with BOOP require treatment with the anti-inflammatory, corticosteroid medication, usually in the form of prednisone. This therapy often results in dramatic improvement with resolution of symptoms within days or weeks. In some situations, the BOOP may recur as the dose is decreased, but the BOOP will respond to an additional course of treatment.
