I am 40 years old and was diagnosed with Histoplasmosis about 10 years ago after a lung cancer scare in the emergency room. I complained of chest pain/back pain whenever I inhaled (turns out it was a pulled back muscle!), but when they ... [More] took a chest x-ray they discovered 2 spots they thought were cancer, one about the size of a dime and one the size of a nickle... They diagnosed as histoplasmosis, and these spots are calcifications. But I'm still scared of developing lung cancer, as I had smoked cigarettes for about 15 years before the diagnosis but have just smoked occassionally the past 10 years since finding out. My fear is that the tar from cigs accumulates on the calcification and never leaves, even though my lungs have 'pinked back up', which could eventually cause cancer? Are there any new medical ways like laser or surgery to take out these calcifications? Should I never, ever smoke again???
