Hi Leah., thanks for the comment. My mom is not a smoker but I know that lung cancer can hit non smokers as well as spread from other undiagnosed primary cancers. I'm hoping that this is just a severe case of allergies but I also am trying not to be too much in denial of the situation either. I saw her today and I definitely noticed that she had coughing fits several times. In the morning she wakes up with a hoarse voice but it seems to go back to normal as the day progresses.
