Epidemiological aspects in breast cancer

Breast cancer represents one of the main public health problem, with a special epidemiological interest, both at the national and international level. A retrospective epidemiological study during the last 11 years (1990-2000) concerning new cases and incidence of the breast cancer at the national level, in Dolj county and in the 1st Surgical Clinic Craiova was made, by using of a comparative analyses which parameters were processed by modern statistic methods. Time evolution equation of the new cases all over the county showed us that more than 208.52 new cases than in the previous year appeared every year. If such an increased rhythm were held, about 6800 new cases would be every year up to 2100. As concerning breast cancer frequency, both at national and local level, a significant increase can be noticed during the last period. At national level the incidence increased from 3.3@100000 in female in 1950 to 29.2@100000 in 1990 up to 46.2@100000 in 2000. We noticed an increase of the incidence with 58.2% at the national level and 86% in Dolj county, in 2000 compared to 1990. By using a comparative analyses on age grouped we could establish a significant frequency of cancer in the patients of 40-49, 50-59 and 60-69 years old, with two frequency peaks for 45-49 and 60-64 subgroups, both at national and county level and also in 1st Surgical Clinic.
