[Incidence and mortality due to cancer in Navarre, 1998-2002. Trends in the last 30 years].

Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall.
