We only included subjects more than 11 years oldwith histopahological diagnosis confirmed. Data were obtained fromclinical charts. We obtained 2.011 cancer records; female were morefrequent affected (63,5%). The most frequently cancer was: cervix(17,0%), skin (14, 4%), female breast (12,2%), stomach (8,2%), lung(4,4%), prostate (2,7%), thyroid (2,4%), ovary and annexes (2,3%),rectum (2,3%), and esophagus (2,0%). The histopathologycal typeswere: Squamous cell carcinoma in cervix uteri (85.2 %), basocelularcarcinoma in skin (67,0%), invasive intraductal in female breast(78,0%), intestinal adenocarcinoma in stomach (32,1%), adenocarcinomain lung (21,3%), adenocarcinoma in prostate (76,4%), papilarcarcinoma in thyroid (43,0%), serous papilar cystadenocarcinoma inovary and annexes (10,6%), adenocarcinoma in colon and rectum(57,4%), and squamous cell carcinoma in esophagus (24,4%). Thefirst four diseases entities were preventable, reflected our need toimprove education in health promotion and prevention. We hope thatthis study will be the basis for future cancer¡¯s risk factors studies. %K Institutional cancer registry %K cervical uterine neoplasm %K skin neoplasm %K breast neoplasm. %U http://caribdis.unab.edu.co/pls/portal/docs/PAGE/REVISTAMEDUNAB/NUMEROSANTERIORES/REVISTA%209%201/PAG14_19.PDF
