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...
Use the following to answer questions 19-21 Breast cancer is one of the leading causes of death in women prior to age 50. A study of the effectiveness of regular breast self-examination (BSE) reported in the American Journal of Public Health found that 23 of 53 women who discovered a tumor through BSE had a tumor in an early stage. Of 178 women who discovered a tumor by accident, 48 had a tumor in an early stage. Let p1 and...
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...

A prospective study of Norwegian women who were followed between 1986 and 2009 was conducted. Within that period (1995-2005), a national mammography program was gradually implement ed, with biennial invitations send to women age 50-69. The participants of the study were all women aged 50-79 between 1986-2009. The mortality rate ratios compared women who were invited to screen to those who were not invited, with a clear distinction between cases of breast cancer diagnosed before and after the invitation to...
We know that the proportion of women who have been diagnosed with breast cancer in the general population is 0.013 or 1.3%. We think that a meaningful difference in proportion of women who have ever been diagnosed with breast cancer is |p0-p1| = 0.02 or 2% difference. for all cal. let alpha = 0.05 A. What sample size is needed to have 90% poor to detect this difference assuming that we use a two sided test. B. If we have...
Problem 1. The HIP trial. If breast cancer is detected early enough, chances of successful treatment are better. Do screening programs speed up detection enough to matter? This was the question asked by the first large-scale trial run by the Health Insurance Plan (HIP) of Greater New York, starting in 1963. The subjects were 62,000 women aged 40 to 64. Half were randomly assigned to a screening group (which included regular exams and X-rays) and the other half were randomly...
Couple questions regarding the ethics of breast cancer screenings and tests. Open to opinions and/or factual answers. a) If either a women or her mother tested positive for a BRCA gene mutation that increases the risk of developing breast cancer in the future, is a prophylactic double mastectomy appropriate? b) What are the issues surrounding these types of tests, how should these issues be addressed, and who should have access to these test results? c) Should the women's daughter (who...
