Question

What does it mean to "belong to a continuum" in relation to disease categories?

Answer 1

It means that the conditions within the category are related to one another, and are really progressions of the same process. Tumor progression is a common example of this - roughly, the steps you would see along the way are dysplasia (abnormal cells), carcinoma-in-situ, and then invasive carcinoma. Each of these stages can have a different name - for instance, in cervical cancer, the dysplastic stages are classified as cervical intraepithelial neoplasias (CIN), and are not considered cancer, though they are clearly progressions along the same path, as a certain percentage of these become a type of cervical cancer (squamous cell carcinoma, adenocarcinoma, etc.). Thus, CIN and cervical cancer would belong to the same continuum, despite being distinct conditions

Answer 2

Can you explain this is simpler terms? Exclude the examples maybe?
