My 80 year old mother in law smokes and drinks alcohol. Over the past year, her voice has become increasingly hoarse. At this point, she can only speak in a hoarse whisper. She also has lost a lot of weight. We can t get her to see a doctor. She hasn t been to a doctor in 6 or 7 years. I am worried she has lung cancer, throat cancer, or a very serious degree of COPD. Which is the more likely diagnosis and what suggestions do you have to help us get her to see a doctor.
