Hello Doctor! My Husband Had Their Annual Physical Exam And

Hello Doctor! My husband had their Annual Physical Exam and the chest X-ray shows suspicious upper lobe densities need apicolordotic view, would that mean a person will have to take medications for PTB eg MyrinP Forte? He is a regular smoker, and had been coughing on and off for weeks now. My concern is that while waiting for another test, what can be done to relieve his cough apart from quitting to smoke. Also, how will it affect my children's health? Thank you so much and I hope you can help me with this.
