Thanks for posting,
First you should know that having recurrent sore throat and husky voice is not equivalent to having laryngeal cancer
( a series of criteria and diagnostic tests need to be conducted to reach to that conclusion). So I suggest you visit an ENT specialist
so you can get properly examined and maybe provided with appropriate treatment.
As for your husband's urinary tract
problem, it seems to me that your husband is still having the stone or has developed an infectious complication of the previous stone. His condition requires immediate consultation with a urologist
Hope this helps
