@janrn1 The decision to treat by a doctor who previously didn’t want to treat is based on a progressively worsening image on CT scan and an increase in some somatic symptoms (cough, chills, fever, fatigue and/or weight loss.) A worsening of a patient’s quality of life is a reason to treat. Many patients talk about their life “before” MAC as compared to their life “after” a MAC diagnosis. For example, I used to be a total type A personality before MAC and the Ever- ready Bunny with boundless energy. That person moved out when MAC moved in. There are lots of factors a physician will consider since treatment is often grueling. I am confident and hopeful that the treatment I am doing will kill the MAC. There is not a “one size fits all” as Terri, our mentor has suggested many times. irene5
