Developed countries: progressive decline in the incidence of prostate cancer in the last decade Developing countries: Paucity of data in this regard from developing countries of West Africa. This study of 10-year data emanating from a Cancer Registry in Nigeria aims to add to available data.
Data from Kano Cancer Registry on all biopsy validated prostate cancer cases were retrieved and analyzed for age distribution, age-adjusted incidence rate and tumor grade.
2004 – 2013 studied 626 CaP 11.2% of all cancers and 23.9% of all male cancers The ages ranged from 30 to 122 years with mean of 67.2±10.6 years. It ranked 1 st among male and 3 rd among all cancers.
The Age-standardized rate was 26.4 per 100,000 population and rates increased progressively from the 4 th decade to the 7 th and over, increase in incidence rate of 37.6% between and crude increase of 221%
Gleason scores 5 – 6, accounted for 37.7% ≥70 years, high grade tumors were more frequent (p = ).

In disparity to data from developed countries there is an increase in incidence rate for prostate cancer among Nigerian men, higher grade tumors are more frequent among the elderly. There is need for institution of a national screening program.
