Background and Objectives: Cancer is an increasing problem in Africa. This study analyzes the profile of cancers recorded in the second decade of Kano cancer registry (KCR), and compare data with a similar previous 10 years (1995–2004) study in the registry to detect changing patterns. Materials and Methods: Cancer cases received by the registry from January 2005 to December 2014 were retrieved from the records and classified by organ/sites of affectation in accordance with the international classification of diseases for oncology. The data are presented in tables according to the organ/sites and ranked accordingly. Results: A total of 47,734 specimens were received within the study period out of which 6548 (13.2%) were malignant. The malignant cases comprised 3598 (54.9%) females and 2950 (45.1%) males (f: m = 1.2:1); there were 516 (7.9%) Paediatric cancers in the series. Overall, breast cancer (14.1%) was the most frequent followed by cancers of the cervix (11.1%), prostate (10.9%), nonmelanoma (nm) skin (7.3%), and colorectum (7.2%), respectively. The leading six cancers among females were the breast (25.0%), cervix (19.8%), colorectum (6.8%), connective tissue (6.6%), nm skin (6.5%), and uterus (5.7%). The corresponding ones in the males were prostate (24.7%), bladder (10.9%), nm skin (8.2%), colorectal (7.8%), connective tissue (7.5%), and eye (4.8%) cancers. Retinoblastoma was responsible for more than half of all Paediatric cancers (61.4%). Conclusion: This study detected some change in the pattern of cancers in KCR. More females than males are affected, and breast cancer is the most common malignancy among women. This contrasts with the previous study which showed male predominance and cervical cancer as the commonest malignancy in women. Prostate and bladder cancer still remain the most common malignancies in men. Data from this study will help to further focus efforts and resources toward tackling the most prevalent cancers in our region most of which are potentially preventable.
