Staging classifications are a coded format, usually numerical, that
generally have increasing values that represent which of the following?
More aggressive cancer
More extensive cancer
A higher grade of tumor
A higher morphology code Ans: More extensive cancer
Staging classifications are a coded format, usually numerical, that have
increasing values that represent greater extent of disease, or disease
involvement. A higher stage cancer is not necessarily the most
aggressive as some cancers are by nature more aggressive than others.
Tumor grade is different than staging and is used to describe how much
or how little the cancer cells resembles the normal tissue from which it
arose. The morphology code denotes the type of cancer and does not
represent stage.
