Incidence rate of breast cancer
Breast cancer is the most common cancer in women in the developed world. In total, it accounts for about 20% of cancers in women. It is one of the most important causes of premature mortality. Risk factors for the occurrence of breast cancer are: demographic factors, maternity factors, hormones, alcohol, obesity, ionizing radiation, mammographic breast opacity and heredity.
Women over the age of 50 get sick more often, about 20% are younger. The probability of an individual born in 2014 to get cancer by the age of 75 is 7.4%
In Slovenia, in the period 2010-2014, an average of 1,265 women were diagnosed with breast cancer annually, and 402 of them died. The relative five-year survival of breast cancer patients is improving and in the period 2010-2014 was 85.1% for women of all ages.
The chance of a cure is high if breast cancer is detected in time, when it is still in the early stages of development. For the purpose of early detection, the National Breast Cancer Screening Program DORA is organized in Slovenia, as part of which women aged 50-69 are invited to undergo screening mammography. Mammography is the most reliable and accurate method for identifying initial cancerous changes in the breast, which can detect cancer when it is not yet detectable.
Breast cancer can be prevented and its frequency reduced with appropriate preventive measures. Encouraging responsiveness to the screening program, raising awareness of the importance and education of self-examination and promotion of a healthy lifestyle - preventing the development of risk factors such as obesity, smoking, excessive alcohol consumption and exposure to harmful environmental factors.
The incidence rate of breast cancer shows the average annual incidence of breast cancer per 100,000 inhabitants during the observed five-year period. An age-standardized rate is calculated, which enables mutual comparison of populations with different age structures.
Age-standardized rate per 100,000 women.
The incidence rate of breast cancer is the ratio of the number of new cases of breast cancer in the observed population of women in one calendar year to the number of women in the observed population at the middle of the same calendar year, multiplied by 100,000.
The disease category according to the ICD-10 classification, which is included in the calculation, is C50.
New cases of breast cancer
The direct standardization method is used to calculate the age-standardized rate, where the Slovenian population from 2014 is used as the standard population. The incidence rate of breast cancer is shown as an average of five consecutive years.
