Artículo científico -- Universidad de Costa Rica. Isntituto de Investigaciones en Salud, 1989Data from the national tumor registry of Costa Rica for the yeas
1979-1983 have been used to calculate incidence rates for the major
cancer sites by age, sex, urban-rural residence, and geographic region.
Recent trends in mortality rates are also presented. Results are compared
Mutilate from elsewhere in Latin America, U. S. A., Europe, and Japan.
Stomach cancer is the most frequent neoplasm in Costa Rift; although
rates are declining, they are second only to those observed in Japan.
There are marked variations in risk by region, suggesting important
enviromental influences in etiology. The cervix is the major female site;
rates are declining in young women, probably doe to the introduction of
saweniog programs, although these do not seem to account for the
geogeaphic variations in invasive cancer incidence. Breast and prostate
cancer show moderate rates, while those for colon and rectum cancer are
low; increases in mortality rates for these sites are small, and involve
mainly the older age groups. In contrast, rates of lung cancer are
inaeasin ' g dramatically in both sexes. In the childhood age group, very
high incidence rates are observed for two neoplasms: Hodgkin's disease
and acute lymphocytic leukemia.Universidad de Costa Rica. Instituto de Investigaciones en Salud.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Instituto de Investigaciones en Salud (INISA
