While surgical tools are constantly being upgraded with the objective of making surgeries less invasive, a recent study has shown that in one out of every 300 cases, surgery performed using the power morcellator, a newly-developed tool used in treatment of uterine cancer, has actually resulted in the spread of the cancer in the patients body. However, the Center for Disease Control (CDC) plans to continue to allow the use of morcellators in oncological treatment as long as physicians stringently select the patients to whom such treatment is administered.
Which of the following would be most useful in assessing the CDCs plan?
(A) Whether banning the use of a surgical tool is a drawn-out process as it requires multiple levels of authorization
(B) Whether patients are aware of the risks associated with surgical procedures performed using minimally invasive techniques
(C) Whether some patients will continue to benefit from surgical treatments performed using power morcellators.
(D) Whether the effects of a surgical procedure can be determined before the procedure is performed.
(E) Whether other surgical tools currently in use have been known to cause negative side effects, but have not been banned by the CDC.
