Is non-hodgkin lymphoma curable?

Depends: There are 3 basic types: low grade, intermediate, and high grade lymphoma. Intermediate and high grade are potentially curable because they are replicating rapidly. Low grade lymphomas are not curable because typically replicating slowly. Low grade are only treated when needed. Hope this helps.

Some varieties: Are curable, others resist treatment, and some are 'indolent' and can recur many years later and then respond for many more years.
