I'm really worried about my 67-year-old mom. She had covid pneumonia and developed post-covid lung fibrosis. The doctors assured us there was no need for concern since she only had a dry cough and no symptoms. A year down the line, we did a routine CT scan and now there's a 3 cm lung mass and multiple nodules up to 9mm in her right lung. Could this be due to the fibrosis she had after covid? I'd really appreciate some guidance on what to do next.

Pulmonologist opinion is advised to the patient.
