Chapter 5 WS Flashcards
1
Q
what is relative survival rate?
A
Compares survival among cancer patient with that of people not diagnosed with cancer. It represents the percentage of cancer patients who are alive after a designated time period (usually 5 years) relative to persons without cancer. It includes patients who have been cured and those who have relapsed or are still in treatment.

65
What is the physician able to do with digital mammography that can’t be done with film/screen mammography?
The contrast can be manipulated with digital mammography allowing the physician to lighten or darken a portion of the image as well as magnify areas of concern.
