In 2023, which chronic disease had 165,000 new cases in Australia?

• A. Diabetes.
• B. Cancer.
• C. Arthritis.
• D. Cardiovascular disease.

Answer: (B)

The key idea here is incidence—the number of new cases diagnosed in a year. In 2023, cancer had about 165,000 new diagnoses in Australia, which is higher than the number of new cases for the other chronic conditions listed. This reflects how many common cancer types there are (like breast, prostate, colorectal, melanoma, lung) and the combined effects of an aging population and screening that detect new cancers each year. The other diseases tend to have large populations living with them, but their year-to-year new diagnosis counts are typically lower than cancer’s. So cancer is the best answer because it has the largest number of new cases in 2023.
