A patient who has been told by the health care provider that the cells in a bowel tumor are poorly differentiated asks the nurse what is meant by “poorly differentiated.” Which response should the nurse make?
A. "Your tumor cells look more like immature fetal cells than normal bowel cells."
B. "The cells in your tumor have mutated from the normal bowel cells."
C. "The cells in your tumor do not look very different from normal bowel cells."
D. "The tumor cells have DNA that is different from your normal bowel cells."
Correct Answer: A. “Your tumor cells look more like immature fetal cells than normal bowel cells.”
Option A: An undifferentiated cell has an appearance more like a stem cell or fetal cell and less like the normal cells of the organ or tissue.
Option B: All tumor cells are mutations from the normal cells of the tissue.
Options C and D: The DNA in cancer cells is always different from normal cells, whether the cancer cells are well differentiated or not.
