Hi, My Name Is Olga I Am 32 Years Old,

Hi, my name is olga i am 32 years old, i have history before when i was 23, i got positive in Ptb, i took medicine in 6 months, 6 months of injection, then i finish it, today i just recieve my result of chest xray, i have suspicious densities on upper lobe, so they suggest me to apicolordotic xray, question, can my ptb would be back again? Or the doctor just saw my scar? Im worried, is it too critical? This is my problem when i am always applying at abroad im always failed at medical exam. Is there any cure too to remove the scar if ever? How about milk everyday.
