I Have Been Having A Real Weak Voice And Feeling

I have been having a real weak voice and feeling very tired for about 4 months now. I am 51 years of age my dr. wants to send me to get checked out for growths in my throat . I have not smoked or drank in twenty three years. I also have a growth on my gallbladder that was looked at a couple years ago the dr. said that is not uncommon. I feel like I am eighty years old not liking that at all. Any other ideas.
