After complaints of over 4 years, I found a doctor that listened to me and was sent to get a MRI and then a PET scan.The scan showed a mass or spot. Saw a thorasic dr. and he talked with me and I'm scheduled for a biopsy in two weeks. If the bio shows something I may have to get the lower part of the right lung removed, if it shows something else, I may be required to start treatment. I was in a daze and tried to take notes but could not comprehend all that was said. Will call monday for another appt. and take a friend with me that's a nurse to help me grasp what all is being said. That's why i posted as a new person. Also, I got my xrays for the past 4 yrs. from another dr. and hospital, and I was told that a small spot showed then but i was never told. But this site has given me hope. Thanks to all of you.
