Doctors refer to cases of asthma that are caused by allergies as atopic asthma. Atopic asthma is the most common form of asthma and tends to run in families. Doctors and patients must take special care to watch out for and address these concerns through a complete diagnosis and regular checkups. Doctors tell you that it is incurable, but they only mean that they themselves can’t cure it with drugs or surgery. They don’t like the idea that there is a free cure from which they can make no money.
