Hi. Ive done chest xray last june 2017 and the result was normal. And it was repeated today feb.10, 2018 find out that there was a suspicious density on right upper lung. And suggested to repeat xray for apl view.? Is it possible that I develop ptb at that period of time. And I havent experienced any symptoms of ptb?. Hoping for a good answer about it. Thank you and godbless.
