Abstract
Background: Our pandemic of covid-19 has not ended yet. However, we have to move forward that other important aspects of research need to be continued, cancer cases as one of the health problems that we should have noticed. Because nearly half of the new cases and more than half of the cancer death worldwide in 2018 are estimated to occur in Asia in part because the region has nearly 60% of the global population.1-3One in 5 men and one in 6 women worldwide develop cancer during their lifetime. Bali as one of the parts of the Indonesian Country had no cancer registry yet.

Methods: Our crossectional study which gathers secondary data from pathology reports from 2017 and 2019 and records clinicopathological aspects like age, gender, and cancer topography. We collected cancer registries from government and private hospitals in Bali. We used consecutive sampling for the malignant lesion. The data were statistically analysed by SPSS version 23.

Results: Totally there are 4821 cancer cases recorded, 3020 cases (62,6%) in females and 1801 cases (37,4%) in men. The most common cancer in females was breast cancer accounted for 15% of cases and nasopharyngeal cancer accounted for 4,9% of the most common cancer in men. In addition, the peak age of cancer is predominantly 50 - 54 years in females and 60 – 64 years old in men. Both females and males who suffered from cancer had the highest frequency between ages 51-55 years old. Moreover, based on each sex, the prevalence rate of males who suffered from cancer was 2.8 % and for females was 4.7%

Conclusions: Our study gives preliminary data about cancer epidemiology based on clinicopathology data (age, gender and cancer topography), especially in Bali. We believe our study will be valuable for further research and primary prevention of the cancer burden in Bali.
