CAPE Biology Unit 2 · May/June 2025 · Paper 2 · Question 3(c)

University medical students investigated patients' knowledge of signs and symptoms of various cancers and diabetes, and possible prevention strategies. Preliminary studies in outpatient clinics involved males and females aged 45-64 in a Caribbean territory. Table 3 shows the results. Students also found family health history knowledge (of all known non-communicable disease history in immediate relatives) was equally low at 33% in males and females.

Using the data in Table 3 and the information provided, discuss the factors that may affect the distribution of diabetes and cancer in the Caribbean. You MUST present your response in complete paragraphs.
