Prostate-specific antigen (PSA) test is a common screening test used for detecting prostate cancer. From Harvard Medical School “Prostate Knowledge” webpage. Is PSA reliable? Although PSA testing can help catch prostate cancer at an early stage, having an elevated PSA (generally considered more than 4 ng/ml) doesn’t necessarily mean that a man has cancer. Noncancerous conditions, including benign prostatic hyperplasia (BPH), or an enlarged prostate, and prostatitis, can raise PSA levels. In fact, studies have shown that about 75% of...

Suppose a particular woman tests positive; what is the probability that she has breast cancer?   To pin this question , please consider a population in which 1% of women have breast cancer, and a mammography test which has a 90% chance of returning a correct result. That is, if a woman has cancer then there is a 90% chance the test will be positive, and if a woman does not have cancer then there is a 90% chance the test...

We want to figure out if lung cancer is related to smoking or not. Suppose that we know 0.3 % of the people has lung cancer and 85% of the people with lung cancer were a current or previous smoker. Also we know that 25% of the people who do not have lung cancer, smoke. With these information, answer the following parts: (5 points each) a) what is the probability of having lung cancer in non-smokers? b) What is the...

Suppose that a screening test for breast cancer has 95% sensitivity and 90% specificity. Assume 1% of the population being screened truly has breast cancer. a. If you really do have breast cancer, what is the probability that the test says you do? b. If you really do not have breast cancer, what is the probability that the test says you do? c. The screening test is applied to a total of 15 people; 5 who really do have cancer...

A test for ovarian cancer has a 2% rate of false positives (i.e. 2% of women who don’t actually have ovarian cancer test positive) and a 0% rate of false negatives.   Data collected by the Cancer association estimates that 1 in every 2500 women over 35 years of age having ovarian cancer. Answer the following questions. [All numeric answers should be accurate to 6 decimal places] What is the probability that a randomly selected woman over the age of 35...

5. In medical tests the prevalence of a disease in a given population is the percentage of the population that has the disease. For a population with a known prevalence, the positive predictive value (PPV) of a test is the probability that a person in the population that tests positive actually has the disease. The negative predictive value (NPV) of a test is the probability that a person in the population who tests negative, in fact, does not have the...

A person takes a test to detect the occurence of a disease. The test’s characteristics are such that a person testing positive has actually a 70% chance actually having contracted the disease. Meaning that a person not having contracted the disease has a 30% chance of testing positive to it. The test’s results are used to allow a person to exit a quarantine – because having the disease makes them immune to it and they are no longer in risk...

Mammograms are a relatively inexpensive and nonintrusive way to test for breast cancer. Suppose that mammogram screenings are 93% specific and 87% sensitive. This means that those without breast cancer test negative 93% of the time and those with breast cancer test positive 87% of the time. Answer the following questions as if 12.6% of all women have breast cancer. a) Given that a women tests negative, what is the probability that she has breast cancer? (b) Given that a...

The prevalence of a disease D among the population is 3%. There is a diagnostic test for disease D. The sensitivity of this test is 99%, this means that the test is positive given that the person has the disease. The specificity of this test is 98%, this means that the test is negative given that the person does not have the disease. a) Given that a person tests positive, what is the probability that the person does not have...

Suppose that a medical test run on 372 people resulted in 38 positive results. Of those, 22 people were eventually confirmed to have the illness. Among the people who tested negative, 3 were eventually diagnosed through other means, and the rest were healthy. Find the sensitivity of the test, the specificity of the test, and the positive and negative predictive values. The positive predictive value is the probability that a person is ill given that they tested positive, and the...
