Cancer is one of the most common chronic diseases that cause high morbidity and mortality. In the evaluation of all illnessand its impact on the community, a surveillance system becomes necessary to allows us to know its incidence. Cancersurveillance is achieved by the population-based cancer registry. Methodology: The Population Based Cancer Registry ofMetropolitan Area of Bucaramanga (RPC-AMB) collected information from the years 2000 to 2004, in patients with anymalignant cancer the which include both invasive and in situ behavior in addition to reside within this geographical area . TheCancer Registry also collects data on brain and nervous system tumors classified as benign or those that have uncertainbehavior. Basal cell cancers of the skin were included during the two first years as well as all the intraepithelial neoplasm ofthe cervix. Active collections of information at all sources by registry staff were made (Hospitals, Health care institutions,especially oncology centers and Pathology and Hematology Laboratories and some specialist in oncology attention). Theinclusion approaches are verified and collects data on specific sociodemographic information (age, gender, residence, placeof birth, etc.) and on the anatomic site of the tumor, the cell type of the cancer, behavior and extension on each individualdiagnosed with cancer. Each case was coded using the International Classification of Diseases Oncology Third Edition (ICDO-3), for topographical and morphological code. The data was entered into a computer with CanReg-4 software that is aconfigurable computer program designed for cancer registration in population-based registries and was provided as aservice by the Descriptive Epidemiology Unit to members of the International Association of Cancer Registries. This softwareprovides the number of cancer cases (frequency) and the incidence rates. The quality control included exhaustiveness of thecases and information, verification of the diagnosis, control of duplicated cases, as well as code and typing quality. It was notpossible to include the cases obtained on the death certificate. Results: from 2000 to 2004, the Cancer Registry collecteddata on 5,939 new cases (without basal cell carcinoma), equivalent to diagnose 3.3 new cases per day. Every year, 858residents of the Metropolitan Area of Bucaramanga died by cancer (average of 2,3 cases per day); 57.0% of the casesaffected females (3,365 cases) and 43.0% males (2,574 cases), the relation female:male is 1.3:1. The annual crudeincidence rate in male is 107.7/100,000 inhabitants, and in female is 128.2/ 100,000 inhabitants; the age-adjusted incidencerate (TEE) it is 162.6 and 146.5 for 100,000 inhabitants, respectively. Excluding basal cell carcinoma, the most frequentcancer in males is prostate cancer (TEE 45.9/100,000 inh), followed by stomach cancer (TEE 18.3/100,000 inh) and the skinsquamous cell carcinoma (14.7/100,000 hab); among women, the most frequent cancer is breast cancer (TEE 37.3/100,000hab), followed by cervical cancer (TEE 19.9/100,000 hab) and colon and rectal cancer (TEE 9.8/100,000 hab). Conclusions:Compared with the GLOBOCAN 2002 data (A project that estimates the incidence, prevalence and mortality of 27 cancertypes for all the countries of the world in the year 2002), the breast cancer in this region is superior to that estimated for thecountry, while the rates on uterine cervix are very inferior to that estimated. The results of the other localizations in general aresimilar to expected.
