Hello, Shortness of breath has many causes, so it will be interesting to see what your CT shows. I’ve been taking a TKI/med for 21 months (Alecensa), at the time of my diagnosis my shortness of breath was caused by lymph node swelling in my chest, they were restricting the airway. I received relief in the first week of taking the drug. Each drug is different and the root cause of the shortness of breath can be different too.
Wishing you good news this week, and a long successful run on Gavreto.
