Mesothelioma cancer is caused by exposure to asbestos. For most patients in Pennsylvania and across the U.S., the disease develops in the lungs, but it can also occur in the heart, abdomen or testicles. Testicular mesothelioma is rare, with only around 100 known cases. That means it is also frequently misdiagnosed.
A study presented at a meeting of the American College of Allergy, Asthma and Immunology revealed that many people in Pennsylvania and around the country may have been misdiagnosed with a penicillin allergy or may have outgrown the allergy since they were diagnosed with it as children. In some cases, people may develop a rash or some other condition when they are given penicillin that is mistakenly identified as an allergic reaction.
