Question

In 2014 there were 2,900 new diagnosis or new cases of breast cancer in Austin, Texas. These women did not have a history of breast cancer. In the same year, 300 women in Alaska were diagnosed with breast cancer. Again, none of the women in Anchorage, Alaska had a history of breast cancer. You share these pieces of information with your family. 1. A: Your mother asks you what do you mean by the term "incidence"? Explain to her the meaning of the term "incidence" (5 points). B: Your mother intensely listens to you and she is so impressed by your knowledge. She then states "Oh! Austin, Texas is experiencing a higher annual incidence rate of breast cancer thar Alaska." You politely correct your mother and explained to her that her statement was inaccurate. What did you tell your mother? (15 points)

Explanation / Answer

Incidence is basically the number of newly diagnosed cases of a disease, and it allows us to determine the probability of a person being diagnosed with that disease.

No, the mother is incorrect because for calculating the incidence rate, we need to divide the number of diagnosed cases with the total number of people who are vulnerable to that disease or are likely to get diagnosed with that disease in that time period.

Hope this helps !
