I know that cancer is not contagious, however, is there any contraindication to kissing someone with throat cancer?  Primary tumor is in the tonsil.  Also, do you know the cause of trismus, when he hasnt had any traditional treatment to date?  (radiation or chemo not the cause..)Thanks for your time and info.   B
Hello dear. Kissing somebody who has throat cancer does not lead to spread of cancer. The cause of Erasmus in such a case is due to the involvement of deep muscle of mouth. Hope that solves your queries. Thanks
