@lls8000 thank you for that...I start Radiation SBRT on Monday, and am thinking of questions to ask about possible side effects. For example, cough medicine, steroids, mucinex, inhalants..I have used all of these medications, inhalants prescribed daily, when experiencing upper respiratory infections. Also what kind of monitoring is done, I know ct scans but unsure about any kind of bloodwork..Thus far the only bloodwork I was required to do was for the bronchoscopy.. Would the Radiation Oncologist request monitoring bloodwork if there is such a thing..Any suggestions would be appreciated.. I plan to ask all of the above when I meet with Radiologist on Tuesday (2nd Radiation appointment) but may be missing something...thanks for your responses and encouragement..
