Sending prayers, BUT I never advocate for biopsies as they can spread the cells of cancer and such BUT at the least have the doctors split the biopsy and have half of it go to a MYCOLOGIST who will test for fungus/mold. A Pulminologist this guy ( www.knowthecause.com ) knows, says they come back 99%ish fungal etiology and has them go on antifungal meds and perhaps even silver (inhailed ) cant remember for the cure, I would add a parasite med and or herbs to that..
