  1. Notes: Unless stated otherwise, all values refer to yearly mean for period 2010–2014; 1 – values in Euro currency (€) calculated using constant average 2010–2014 exchange rate: 4.14 zlotys per €; 2 – real data is used for population insured in the Social Insurance Institution; for those insured in the Agricultural Social Insurance Fund the data is estimated; 3 – real value for year 2012 [30]; for other years the value was estimated; 4 – the average value based on [31,32,33]; 5 – due to a lack of BC-specific data, the rate refers to caregivers in all cancers in Poland [34] and the share of those with BC in total cancer patients is used to estimate the number of working caregivers for BC patients; 6 – due to an unavailability of BC-specific productivity reduction of caregivers, data for all cancers in Poland is used [34]; 7 – the timespan covers the period of potential economic activity of the youngest women who develop BC during the period investigated; based on [35]; 8 – the values show an equivalent of people who are completely unable to work assuming that a partial inability to work corresponds to 0.75 of complete inability to work
