Final answer:
The question does not provide the necessary information to determine the exact percentage of women with mastodynia who have a malignancy.
Step-by-step explanation:
To determine the percentage of women with mastodynia who have a malignancy, we need to know the number of women with mastodynia and the number of them who have a malignancy. The question does not provide this information, so we cannot determine the exact percentage.
However, if we know the total number of women with mastodynia and the number of them with a malignancy, we can calculate the percentage by dividing the number of women with a malignancy by the total number of women with mastodynia and then multiplying by 100.
For example, if out of 200 women with mastodynia, 5 have a malignancy, the percentage would be (5/200) * 100 = 2.5%. Therefore, none of the given answer choices are correct.
