Without more information on his cough, especially the duration of it, and more information on the "few spots" it is not possible to speculate on the cause of your husband's cough. For example, if this is a new, acute cough that started within the past 2 to 3 months, one would have to consider an infectious cause, such as pertussis, commonly called whooping cough, that is increasingly been seen in adults of all ages. In that case, the "spots" might not even be related to the cough.
There are many, many causes of cough and the overwhelming majority of these causes are benign – not lung cancer, especially so in non-smokers. I hope that that is reassuring,
Good luck to you and your husband.
Yes On Sept 19th I posted a question and still haven't had anyone reply back to me everyone else gets a reply back. Very concerned.
