weird question I came across in an online test series-pls give me your views

[Guest guest]

Dentists are encouraged to carry out a thorough soft tissue examination and be

vigilant for any lesions that might possibly be malignant or have malignant

potential. Currently it is not recommended that dentists use a mucosal staining

method for screening the general population for oral cancer.

What is the most likely reason for this advice?

A. Unnecessary intervention where there is a false positive test result

B. False reassurance where there is a false negative test result

C. Low uptake of screening by those with low risk

D. Low uptake of screening by those with high risk

E. Negative result reinforcing existing bad habits
