Re: Mass on lung of my father
Ohio is the Histoplasmosis capital of the world, so that's not surprising. Since you said that your dad has been in great health, he most definitely had to come into direct contact with a large amount of inoculum for him to even show any symptoms.
I could randomly pick out 100 Ohioans on any given day and test them for Histo and 90%of them would test positive for it. However, the majority of those people will never know that they are infected with it because it's very rare for a healthy person to show symptoms. When a person starts showing symptoms, it means they have a serious condition in which their immune system is impaired or in the case of your dad, they were exposed to a large amount of the pathogen of one time. It can be nasty to treat, but when they catch it early, like in the case of your father, they can effectively treat it with the right combo of meds. I'm really glad to hear that he's responding to the second treatment and that it wasn't cancer!
