Doctors have suggested that women should take the Pap test every three years to screen for cervical cancer. Since the Pap test is meant to detect abnormalities that may lead to invasive cervical cancer, these abnormalities can be treated before cancer develops. Most invasive cancers of the cervix can be prevented if women have Pap tests regularly.
The answer to which of the following questions would be most important in determining whether implementing the suggestion is likely to achieve the desired result?
(A) What percent of women in whom abnormalities are detected actually get invasive cancer of the cervix?
(B)What is the time lag between appearance of abnormalities and subsequent development of cervical cancer?
(C) Do the insurance companies cover the cost of Pap test?
(D)Are the causes of development of abnormalities identified?
(E)Do we have treatment for the abnormalities so that cancer does not develop?
The correct option is (B). Let me explain each of the options one by one.
(A) What percent of women in whom abnormalities are detected actually get invasive cancer of the cervix?This question is not as important in determining whether implementing the suggestion of taking the Pap test every three years is likely to achieve the desired result. While it is important to know how often abnormalities detected on the Pap test progress to invasive cancer, it does not necessarily impact the effectiveness of regular Pap tests in detecting and treating abnormalities before they become cancerous. Therefore, this option is not the most important.
(B) What is the time lag between appearance of abnormalities and subsequent development of cervical cancer?This option is the most important in determining whether implementing the suggestion of taking the Pap test every three years is likely to achieve the desired result. The time lag between the appearance of abnormalities and subsequent development of cancer determines how often abnormalities can be detected and treated before they become invasive cervical cancer. A long enough time lag would make regular Pap tests effective in preventing most cases of invasive cervical cancer.
(C) Do the insurance companies cover the cost of Pap test?While insurance coverage is important for patients to receive the recommended tests, it does not impact the effectiveness of regular Pap tests in detecting and treating abnormalities before they become invasive cervical cancer. Therefore, this option is not the most important in determining whether implementing the suggestion of taking the Pap test every three years is likely to achieve the desired result.
(D) Are the causes of development of abnormalities identified?While understanding the causes of cervical abnormalities is important for research and development of treatments, it does not necessarily impact the effectiveness of regular Pap tests in detecting and treating abnormalities before they become invasive cervical cancer. Therefore, this option is not the most important in determining whether implementing the suggestion of taking the Pap test every three years is likely to achieve the desired result.
(E) Do we have treatment for the abnormalities so that cancer does not develop?While having treatment for abnormalities is important, it does not necessarily impact the effectiveness of regular Pap tests in detecting and treating abnormalities before they become invasive cervical cancer. Regular Pap tests are meant to detect abnormalities early, so that they can be treated before they become cancerous. Therefore, while this option is important, it is not the most important in determining whether implementing the suggestion of taking the Pap test every three years is likely to achieve the desired result.
