A new treatment for chronic obstructive pulmonary disease (COPD) is being reported, which may offer hope for people with the breathing condition. The treatment, described as innovative and potentially breakthrough, has been approved or recommended by a health authority, with some reports suggesting it can reduce flare-ups. Reports vary, but the treatment appears to be experimental or newly approved, and may offer promising results for patients, particularly those with hard-to-treat cases or emphysema.
