About 249 cases (89.3%) occurred in those who are 55 years or older at time of diagnosis, with the commonest age group being 60-64 years. The age specific incidence of prostate cancer is 89 per 100,000, both crude and adjusted incidence rates were highest in 2012 (69.4 and 97.4 per 100,000, respectively). There was significant decrease in incidence rates in the initial five years (2004-2008), and increase in rates in the following five years of study (2009-2013). Within the 5-year period from 2004 to 2008, there was an average annual decrease in incidence rate of 9.63% (95% CI: 6.1%-12.8%). However, within the 5-year period from 2009 to 2013, there was an average annual increase in incidence rate of 11.95% (95%CI: 8.72% to 13.04%).
