Handling grade in cancers

[jsstevenson]

Different sources inconsistently provide specific low and/or high grade concepts for some cancers. In the tree- and ontology-based sources, these are usually represented as children of the generic grade-less concept of the specific cancer.

• Is it possible/desirable to retain that relationship? Practically, is there a way to retrieve both the graded and grade-less concept in one search?
