Answer: A. Diagnosis, grade, stage
Explanation: Pathologists study by comparison between what’s normal and what’s abnormal in the human body. They learn what a normal cell looks like and then they can compare it with another cell. If there are differences between the cells, then they document those findings. Pathologists use the following terms when examining cells:
* Diagnosis is the examination of the sample
to help to identify the underlying process
that’s occurring with the patient.
* Grade is the degree of deviation from a
normal cell.
* Stage is the extent of the disease.
