Lung Scar / Fibrosis

Hi! My son was diagnosed with primary complex when he was 5 y/o and completed his 6 months treatment and was cleared buy his pedia-pulmo. 6 y/o na po sya ngayon. Ask ko lang sana if hanggang sa paglaki nila makikita pa din ba sa xray yung fibrosis or lung scar nila? Salamat po!
