A patient in the clinic is concerned because her family has a strong history of colon cancer. The patient asks you what she can do to find out if she is going to get colon cancer. Why would you suggest genetic testing?
A) Just to calm the patient's concerns.
B) There is a chance genetic testing can tell the patient whether she has colon cancer.
C) Genetic testing cannot yet identify people at risk for colon cancer.
D) Researchers have refined methods for genetics risk assessment, and preclinical diagnosis to identify people at risk for some GI disorders.
Ans: D
Feedback: Researchers have refined methods for genetics risk assessment, preclinical diagnosis, and prenatal diagnosis to identify people who are at risk for certain GI disorders (eg, gastric cancer, lactose deficiency, inflammatory bowel disease, colon cancer). You would not suggest genetic testing just to calm a patient's concerns. You would not refer a patient for genetic testing for a diagnosis of colon cancer.
