1. Among women in the United States, breast cancer has the highest death rate but not the highest incidence.
True
False
Homework Answers
Ans.) True
As per several published report, it is concluded that death rate due to breast cancer amongst women in the United States, is the highest but its rate of incidence is lesser. Though, in recent years, incidence rate of breast cancer have expanded somewhat (by 0.4% per year) and it is the second driving reason of cancer death in women. But the death rate due to breast cancer is quite higher i.e., approximately 2.6%.

Breast cancer is the most common non-skin malignancy among women in the United States, and it is the second leading cause of death from cancer among women (lung cancer ranks Örst). A mammogram is a diagnostic procedure designed to quickly detect breast cancer. Such a test can exhibit two kinds of errors: One error is known as a false positive: The test incorrectly indicates cancer in a healthy woman. The other error (which is more serious error in this situation)...

A breast cancer follow-up study included 218 women diagnosed with breast cancer and 3,823 women without breast cancer. By the end of the study, 72 of the women with breast cancer and 511 of the women without cancer had died. The women with breast cancer were observed for a total of 1,862 person years; the women without cancer were observed for a total of 36,653 person years. Calculate the incidence rate of death for the women with breast cancer. Response...

Breast cancer occurs most frequently among older women. Of all age groups, women in their 60s have the highest rate of breast cancer. It is estimated that 3.7% of women in their 60s get breast cancer. Mammograms are X-ray images of the breast used to detect breast cancer. A mammogram can typically identify correctly 84.9% of cancer cases (sensitivity = 84.9%) and 95.13% of cases without cancer (specificity = 95%). (This is exactly like problem #11) First write down the...

1. A hypothesis has been proposed that breast cancer in women is caused in part by events that occur between the age of menarche (time of 1st menstruation) and the age of first childbirth. The hypothesis is that the risk for breast cancer increases as the length of this time interval increases. To test this hypothesis an international study was set up. Breast cancer cases were identified among women in selected hospitals in the United States, Greece, Yugoslavia, Brazil, Taiwan...

Approximately 3% of women aged 40-50 have breast cancer. A woman with breast cancer has a 90% chance of positive test from a mammogram, while a woman without breast cancer has a 2% chance of a positice result. What is the probability that a woman has breast cancer given that she just had a positive test?

Suppose that among 10,000 women whose mammograms showed no abnormalities, two will be diagnosed with breast cancer within the next two years; and that among women with abnormalities noted in their mammograms, one out of ten will be diagnosed with breast cancer in the next two years. 117% of women in the general population have a mammogram that shows abnormalities, what is the probability of being diagnosed with breast cancer in the next two years among women in the general...

In the United States, heart disease and cancer are the two leading causes of death. If you look at the death rate per 100,000 residents by state, the distributions for the two diseases are roughly normal, provided you leave out Alaska and Utah, which are outliers because of their unusually young populations. The means and standard deviations for all 50 states are given here. Mean SD Heart disease 219 46 Cancer 194 30 a. The middle 90% of the states'...
