The answer to is cervical cancer contagious is yes and no. The virus that causes most cervical cancers, HPV or human papillomavirus, is a sexually transmitted disease, so it's obviously very contagious. BUT, cervical cancer itself is not contagious.
So, when you are caring for someone with cervical cancer you do not need to be worried about catching it. But, to prevent it, practice safer sex to reduce your chances of getting HPV, and that will help you stay healthy.
