[Carcinoma of the colon in La Rioja. Study of incidence in the period 1978-87]. / Carcinoma del colon en La Rioja. Estudio de la incidencia en el período 1978-87.

A study was made of the incidence of colonorectal tumors in the Autonomous Community of La Rioja (Spain) over 10-year period between 1978 and 1987, inclusive. An increased incidence of these tumors is confirmed, with no decline in the age of presentation or in the frequency of detection of early tumors, which suggests that this disease is on the rise. In view of these results, measures leading to the early diagnosis of colonic tumors are needed, such as screening of the general population, particularly groups at risk.
