Breast cancer researchers found that, out of a sample of 1000 women who had been treated for breast cancer, over 60% had had a miscarriage in their lifetime. This led the researchers to conclude that there is a connection between breast cancer and miscarriages, and to encourage all women who have had miscarriages to be screened for breast cancer more frequently than women who have not had miscarriages.



Which of the following, if true, most weakens the researchers' conclusions?

  • a)
    Women who have had miscarriages are also often taking birth control pills, which have a known connection to breast cancer.

  • b)
    Women who have not had breast cancer also have a high rate of miscarriage after age 35.

  • c)
    Women who have had previous miscarriages sometimes use fertility treatments that are thought to have connections with uterine cancer.

  • d)
    In the general population, roughly 6 out of 10 women will have a miscarriage at some point in their lifetime.

  • e)
    Most of the women in the study had also had at least one living child

Correct answer is option 'D'. Can you explain this answer?

Explanation: D is correct because it indicates that the rate of miscarriage in the study sample is no larger than that for the general population. This indicates that women who have not had breast cancer are just as likely to have had miscarriages as women who have been treated for the disease, demonstrating that there is no causal link between miscarriage and breast cancer.
A is incorrect because the birth control pills are a confounding factor; it is just as likely they, not the miscarriages, contributed to breast cancer in the study sample.
B is incorrect because it implies that breast cancer may cause a higher risk of miscarriage, while the researchers are asserting that miscarriage may cause breast cancer.
C is incorrect because the treatments in question are known to have a connection with uterine cancer, but this cannot necessarily be extrapolated to breast cancer.
E is incorrect because the researchers are not asserting that infertility or not having children causes cancer, only that miscarriage does

Weakness in the researchers' conclusion:

D) In the general population, roughly 6 out of 10 women will have a miscarriage at some point in their lifetime.
- This statistic shows that having a miscarriage is a common occurrence among women in general, regardless of whether they develop breast cancer or not. Therefore, the high rate of miscarriage among the women in the breast cancer study may not necessarily be directly linked to their breast cancer diagnosis.
This information weakens the researchers' conclusion by suggesting that the connection between miscarriages and breast cancer may not be as significant as initially thought. It indicates that the high rate of miscarriage among the women in the study might not be a unique factor contributing to their breast cancer diagnosis, as it is a common experience among women in the general population.
