A mammogram was used to screen for breast cancer in 200 women
with breast cancer diagnosed by a biopsy and in 500 age- and
race-matched women without breast cancer. The results of the
mammogram were positive in 150 of the women with breast cancer and
in 100 of the women without breast cancer. b. Compute the i)
sensitivity, ii) specificity, iii) positive predictive value, and
iv) negative predictive value. c. Make a statement about each of
the computations d. If...

Given these facts:
Using the case of testing women for breast cancer (*)
1% have breast cancer
99% don’t have breast cancer
Mammogram tests
In event of a woman with cancer
80% of mammograms detect breast cancer when it is there
(positive)
20% miss it (false negative)
In event of no cancer
9.6% of mammograms detect breast cancer when it’s not there
(false positive)
90.4% correctly return a negative result.

Epidemiologists claim that the probability of breast cancer
among Caucasian women in their mid-60s is 0.003. An established
test identified people who had breast cancer and those that were
healthy. A new mammography test in clinical trials has a
probability of 0.90 for detecting cancer correctly. In women
without breast cancer, it has a chance of 0.975 for a negative
result. If a 65-year-old Caucasian woman tests positive for breast
cancer, what is the probability that she, in fact, has...

16. An epidemiologic study of
breast cancer among elderly women followed 1,000 women, 65-79 years
of age, without evidence of breast cancer over several years. Every
two years the investigators examined the women for breast cancer.
The results were as follows: 12 new cases at the first evaluation,
11 new cases at the second evaluation, 23 new cases at the third
evaluation, and 28 new cases at the fourth (and final) evaluation.
The investigators also noted that 40 women had...

Literature shows that the incidence of breast cancer is 150
cases per 100,000 women aged 45-49 years old annually. The
researchers want to test whether regular intake of vitamin D would
reduce 20% of the risk of the occurence of breast cancer. They plan
to recruit women aged 45-49 years who are free of breast cancer at
the beginning and randomly assign them into two groups, i.e., group
one: women in this group will receive vitamin D treatment, and
group...

Exercise 1: Thirty nine women with a diagnosis of inoperable or
metastatic breast cancer have been followed-up for a number of
years, while under continuous treatment with a medication called
trastzuzumab. The time (in months) each patient remained in
remission was recorded. Remission is is a decrease or disappearance
of signs and symptoms of cancer. Below is the data. 50 74 35 39 21
