The graph shows the incidence and mortality rates for prostate cancer from 1983 to 1998 - HSC - SSCE Personal Development and Physical Education - Question 9 - 2004 - Paper 1

The most likely reason for the significant rise in the number of new cases of prostate cancer between 1988 and 1994 is (C) Increased detection due to more effective screening methods. This explanation accounts for the likelihood that the increase in new cases observed during this period can largely be attributed to improved screening practices that allow for earlier and more accurate detection of the disease, rather than an actual increase in incidence.
