My mother was recently diagnosed with NSCLC. She told me she quit smoking and was on the patch, but I found out she lied and is using an e cigarette instead. I told her to ask her doctor before she even considered it and of course, she didnt. I have found so many conflicting things online about them. Has anyone asked their doctors about them? obviously , they are better than smoking, but with someone in her condition, are they hurting her chances of any improvement? she is on keytruda if that makes a difference . Thank you for any advice on this. I am really starting to feel like she doesn't want to get better of she can't even ask if this is healthy for her. it makes me so sad and frustrated. why go through all of this treatment if you won't take care of yourself?
