My 67 year old mother had serious covid pneumonia and later developed post covid lung fibrosis in her right lung.. all doctors said that nothing had to be done about it as she had no symptoms or difficulty.. just a dry cough.. so we were living in peace.. Now One year later in a routine ct scan, she has lung mass of 3 cm and lung nodules max 9mm in her right lungs.. Did this happen because of her post covid fibrosis?? Please I need to know ??

Pulmonologist opinion is advised to the patient.
