Chronic sinusitis is a common condition in which the cavities around your nasal passages become inflamed and swollen. Despite treatment attempts, it can last for eight weeks or more. Acute sinusitis causes similar symptoms, but usually lasts only a couple of weeks. On the next Mayo Clinic Radio, allergy specialist Dr. Rohit Divekar explains what causes sinusitis and how it's treated. Also on the program, the Centers for Disease Control and Prevention estimates that about 18 million adults and more than 6 million children in the U.S. have asthma. Dr. Divekar outlines the most effective asthma treatments. And, preventive medicine specialist Dr. Deborah Rhodes discusses how molecular breast imaging (MBI) can help identify breast cancer in dense breast tissue. Cancer survivor Kula Shives talks about how her breast cancer was found by MBI after being missed by mammography.
