I am Dr Mbong. The likelihood of your voice hoarseness
being of cancerous origin is likely if you smoke, take lots of alcoholic spirits, have a family history of throat cancer
, strain a lot with your voice or do oral sex
(some strains of HPV virus which can be contracted from oral sex) can cause throat cancer.
Otherwise if you use your voice a lot (at work or somewhere else) especially lately, then you can have voice hoarseness without it being a cancer.
Another cause may be the onset of a palsy of the nerve
that innervates the voice box. It could also be onset of symptoms of a voice box muscle involvement of a myaesthenia gravis (or some other related muscle weakness
disorder) which often worsens with time of the day.
Please see a physician for thorough examination and proper work-up in order to determine the cause.
Courage and wish you the best,
